The NPT Male to JIC Male OneXtreme Adapters are precision-engineered conversion fittings designed to connect NPT (National Pipe Taper) threaded systems to JIC 37-degree flare connections in demanding hydraulic and fluid power applications. The NPT side features a tapered thread design that seals through thread interference and requires the use of high-quality PTFE tape or thread sealant, while the JIC side utilizes a 37-degree cone seat to create a reliable metal-to-metal seal without additional sealing compounds. 

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

NOTE: Proper thread identification and sealing method are critical. NPT threads require appropriate sealant and are susceptible to galling, while JIC connections rely on clean, undamaged flare surfaces. Repeated assembly can degrade NPT thread integrity, and mismatched or improperly installed components can result in leaks or catastrophic failure.
