BSP Hose Fittings Manufacturers

Installation steps for BSP hose fittings
Preparation
Before installing the BSP hose fitting, first ensure that all connectors and hose components are not damaged or deformed, and the threaded part is clean and free of impurities. At the same time, the appropriate BSP fitting specifications should be selected according to the size and use requirements of the hose. The connector products provided by Ningbo Yinzhou Baige Machinery Manufacturing Co., Ltd. comply with the GB/T 19001-2016/ISO 9001:2015 quality management system, with precise product dimensions and easy selection.
Check the hose interface and connector threads
BSP hose fittings are generally divided into two types: parallel threads and tapered threads. Parallel threads generally require sealing washers or sealing rings, while tapered threads are sealed by the threads themselves. Be sure to confirm the connector type and the corresponding sealing method before installation. Ningbo Yinzhou Baige Machinery Manufacturing Co., Ltd.'s connector products are designed with full consideration of sealing performance to ensure that there is no risk of leakage after installation.
Lubricate threads and seals
When making threaded connections, a special anti-seizure lubricant or sealant should be applied appropriately to avoid thread seizure or leakage. This step is an important part of ensuring smooth and removable installation, especially in high-pressure systems. Baige Machinery's engineering team recommends using lubricating materials that meet industry standards to ensure that the joints are durable and have a long-lasting seal.
Tighten the joints manually
During the initial installation, the BSP hose fitting should be screwed into the corresponding interface by hand to ensure that there is no cross-threading or misalignment. If abnormal resistance is found during the hand-tightening process, stop immediately and check the status of the threads and seals.
Tighten with the right tools
Use a wrench of the right size to tighten the joint evenly to avoid excessive force that may cause damage or deformation of the threads. Baige Machinery's product design fully considers the convenience of installation, and the joint surface treatment process is excellent, which is easy to operate and wear-resistant.
Seal detection
After installation, an air-tight or hydraulic test should be performed to ensure that there is no leakage. Baige Machinery provides technical guidance to customers and recommends the use of industry-standard pressure detection methods to confirm that the joint sealing effect meets the design requirements.
Key points to note during installation
Correctly identify the type of joint
BSP threads are available in two types: parallel and tapered. Incorrect selection will result in sealing failure. Baige Machinery's technical support team emphasizes that customers must confirm the type of connector when purchasing and installing to avoid troublesome repairs later.
Avoid thread damage
The thread is the key part of the connector seal. Do not use inappropriate tools or excessive force during installation. The connectors produced by Baige Machinery use high-precision processing technology to maximize the integrity of the thread.
Use suitable sealing materials
For parallel thread connectors, it is recommended to use special sealing rings or gaskets. Conical thread connectors can rely on the thread itself to achieve sealing. Baige Machinery provides a variety of sealing material options to meet the needs of different working environments.
Keep the interface clean
The threads and sealing surfaces should be kept free of oil and dust to avoid affecting the sealing performance. Baige Machinery has strict control over the cleanliness of products and accessories to ensure that they are in the best condition when leaving the factory.
Environmental and medium adaptability
The material of the hose connector should be selected according to the use environment and the conveying medium to prevent chemical corrosion or aging caused by excessive temperature. Baige Machinery provides a variety of materials such as stainless steel and copper alloy to meet the diverse needs of industry.
Regular maintenance inspection
It is recommended that customers regularly check the tightness and sealing performance of hose connectors, and replace aging or damaged accessories in time to ensure long-term stable operation of the system. Ningbo Yinzhou Baige Machinery Manufacturing Co., Ltd. has a complete after-sales service system to support customer equipment maintenance.

The thread type and sealing principle of BSP fitting
First of all, understanding the thread type of BSP fitting is the basis for answering whether sealant or gasket is needed. BSP threads are mainly divided into two types:
BSP parallel thread (BSPP)
The thread is parallel. When connected, the thread itself does not have a sealing function. The sealing is achieved by gaskets or sealing rings (such as rubber gaskets and metal gaskets). This type of connector is common in low-pressure systems or places that require strong disassembly.
BSP tapered thread (BSPT)
The thread is tapered, and the metal seal is achieved by the mutual engagement of the tapered surface of the thread. This sealing method itself has certain sealing performance, but in actual use, sealant may still be required to enhance the sealing effect, especially in high-pressure or leak-prone media environments.
The BSP hose fittings produced by Ningbo Yinzhou Baige Machinery Manufacturing Co., Ltd. are manufactured strictly in accordance with international standards, with high thread precision to ensure tight connection and reduce the risk of leakage.
Professional judgment on whether sealant or gasket is needed
Parallel thread BSPP connector
Since the thread itself is not sealed, it must be used with a gasket. Commonly used gasket materials include rubber, fluororubber, PTFE (polytetrafluoroethylene), etc., which can effectively prevent medium leakage. In the products of Ningbo Yinzhou Baige Machinery Manufacturing Co., Ltd., the matching gaskets are made of high-quality materials, corrosion-resistant and aging-resistant, suitable for a variety of industrial environments.
Tapered thread BSPT connector
In theory, the tapered thread is sealed by thread bite, but the actual working conditions are complicated, and there are inevitably small gaps on the metal contact surface, especially under high pressure or vibration conditions, which are prone to leakage. At this time, sealants (such as sealing tape and sealing paste) can fill small gaps and improve sealing and vibration resistance. Baige Machinery engineers recommend using sealants in high-demand systems to ensure safety.
Sealing selection under special working conditions
In high temperature, high pressure, corrosive media or flammable and explosive environments, the selection of sealing materials and methods is particularly critical. Baige Machinery provides a variety of materials and sealing solutions, and cooperates with professional engineering teams to tailor the best solutions for customers to ensure the safety and stability of the system.
Application tips for sealants and gaskets
Sealing tape (PTFE tape)
When using, it should be evenly wound 2-3 times along the thread direction, avoiding too much or too little winding, ensuring sealing and not affecting the thread bite. Baige Machinery recommends the use of high-quality PTFE tape, which is heat-resistant and corrosion-resistant and suitable for a variety of working conditions.
Sealing paste
Apply evenly to cover the entire thread, especially tapered threads, which can enhance metal bite seals and is suitable for high-pressure systems. The company recommends the use of sealing paste that meets industry standards to ensure no pollution and easy removal.
Gasket
The gasket should be kept clean and intact during installation to ensure a close fit with the end face of the joint. The gaskets manufactured by Baige Machinery have been strictly tested, with stable materials and reliable sealing effects.

The importance and use environment of BSP hose fittings
BSP hose fittings are widely used in hydraulic, pneumatic, chemical, cleaning machinery and other industries, and are often used to connect high-pressure hoses to equipment interfaces. Due to its compact structure, easy installation and good sealing performance, BSP hose fittings have become the preferred connectors in many systems. However, long-term operation in an environment of high pressure, high temperature, chemical corrosion or frequent vibration will inevitably cause problems such as wear, corrosion, and sealing failure. If not maintained and replaced in time, it is very easy to cause leakage or even equipment failure.

Maintenance cycle of BSP hose fittings
The maintenance cycle is affected by many factors. Baige Machinery recommends that customers develop a scientific maintenance plan based on actual working conditions:
Daily inspection frequency
It is recommended that users conduct a visual inspection of BSP hose fittings at least once a month, focusing on thread wear, seal aging, surface corrosion and tightening status. If looseness, deformation or leakage is found, it should be repaired or replaced immediately.
Regular disassembly and maintenance
For continuous high-pressure working environments, it is recommended to disassemble once every 6 months, clean the inside and threads of the connector, and check whether the seal and gasket are damaged. Baige Machinery's engineers emphasized that timely removal of dirt and corrosion can effectively extend the service life of the connector.
Professional testing
In key application areas, professional pressure testing and sealing performance testing are recommended every year. The company provides technical support and can assist customers in developing testing plans to ensure that the connector is in the best condition.
Replacement cycle of BSP hose fittings
The replacement cycle of BSP hose fittings also depends on factors such as the use environment, material, and working pressure. The following are Baige Machinery's recommended guidelines:
Conventional industrial environment
In general industrial applications, high-quality BSP hose fittings can be safely used for an average of 3-5 years. After this period, even if there is no obvious damage to the appearance, it is recommended to replace it to prevent potential risks.
High-pressure and high-temperature environment
In an environment where the high pressure exceeds 20MPa or the high temperature exceeds 120℃, the fatigue and aging of the joint material are accelerated, and the replacement cycle should be shortened to 1-2 years. Baige Machinery provides a variety of high-temperature and corrosion-resistant material joints, which can be customized according to needs to improve durability.
Corrosive media working conditions
When using strong acid, strong alkali or organic solvent media, the surface of the joint is prone to chemical corrosion. It is recommended to replace it every year or maintain it more frequently. The company uses high-quality stainless steel and copper alloy materials to effectively resist chemical corrosion and extend the service life.
Frequently disassembled equipment
For systems that require regular disassembly and maintenance, the joint threads and sealing rings are easily damaged. It is recommended to shorten the replacement cycle to less than 1 year. The joints designed by Baige Machinery take into account the characteristics of easy disassembly and assembly, which is convenient for customers to maintain and operate.
