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

Manufactured from cold worked 316 stainless steel, these adapters provide excellent strength, corrosion resistance, and durability in demanding 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 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 threads, and mismatched or improperly installed components can result in leaks or catastrophic failure.
