Everything you need to know about BSPP threads in hydraulics

BSPP threads are an important component of hydraulic fittings and are used in various applications to establish a safe and reliable connection between hydraulic lines. The abbreviation "BSPP" stands for "British Standard Pipe Parallel" and refers to a thread that is common in the United Kingdom and many other countries.

BSPP threads have a taper angle of 60 degrees and are cylindrical pipe threads. The taper is typically used as a sealing surface, while the flanks of the thread serve to screw and secure the two threaded parts together. Due to their construction and thread design, BSPP threads are a popular choice for hydraulic applications.

Hydraulic fittings are available in many different designs, including weld-on fittings, screw-on fittings, double connectors, screw-in fittings, thread reducers, straight connectors, bulkhead fittings, elbow connectors, and couplings. There are also various types of screw-in fittings, including pre-assembled variants.

Choosing the right thread is important to ensure a secure and tight connection between the hydraulic lines. BSPP threads are a popular choice for hydraulic fittings due to their reliability, availability, and wide range of applications.
