Threaded connectors
Threaded connectors are an integral part of hydraulic systems, providing safe and reliable connections between different parts. Threaded fittings are trusted for their versatility and reliable performance in high pressure environments. To guarantee top performance, attention must be paid to threading properties and sealing methods.
First, let's look at the thread properties. They specify thread size, pitch and type, which are essential for compatibility and leak prevention. The most common thread types are NPT (National Pipe Thread), BSP (British Standard Pipe) and metric thread. Each type has its own characteristics, and choosing the right one depends on the requirements of your system. For example, NPT threads are tapered, which promotes a tighter seal under pressure, while BSP threads can be either parallel or tapered, depending on the application.
Sealing methods are equally important. They ensure that the joint remains leak-free under different operating conditions. Threadlockers, such as PTFE tape or liquid threadlocker, are usually used in threaded fittings. PTFE tape, often called Teflon tape, is wrapped around the threads to fill the gaps and create a seal. Liquid twist locks harden after application, providing a more permanent solution.
Another sealing method is the use of O-rings or tied pins. These are used in conjunction with threaded fittings to improve sealing efficiency. O-rings are installed in the groove of the connector and are compressed when tightened to seal the joint.
