The NPT Female to BSP Male OneXtreme Adapters are precision-engineered conversion fittings designed to connect NPT (National Pipe Taper) threaded systems to BSPP (British Standard Parallel Pipe) connections in high-pressure hydraulic and fluid power applications. The NPT side features a tapered thread design that creates a seal through thread interference and requires the use of a high-quality PTFE tape and/or thread sealant, while the BSPP side utilizes straight (parallel) threads that seal via a cone, gasket, O-ring, or dowty seal, depending on the mating connection. 

Manufactured from cold worked 316 stainless steel, these adapters provide exceptional strength, corrosion resistance, and durability in demanding environments, with special materials available upon request to meet specific application requirements. NPT connections are capable of handling pressures up to 15,000 psi (1034 bar) and temperatures up to 400F (204C), though performance can vary based on size, media, and installation conditions; when combining connection types, overall system capability must always be based on the lower-rated side and associated components. 

NOTE: Proper thread identification and sealing method are critical. NPT threads require sealant and are prone to galling if improperly installed, while BSPP threads rely on correct sealing interfaces. Repeated assembly and disassembly can degrade sealing performance, and mismatched threads or improper installation can result in leaks or catastrophic failure.
