X6H06J15 : OneXtreme Adapter, 0.375 (3/8") Male HP x 0.375 (3/8") Male JIC, 15,000psi

The High Pressure Male to JIC Male OneXtreme Adapters are precision-engineered conversion fittings designed to connect coned-and-threaded high pressure systems to JIC 37° flare connections in demanding hydraulic and fluid power applications. The high pressure side utilizes a 60-degree cone and thread connection to create a dependable metal-to-metal seal for applications up to 60,000 psi (4136 bar), while the JIC side features a 37-degree flare seat that provides a reliable seal without the need for additional sealing compounds and is commonly used in systems up to 15,000 psi (689 bar).

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. Because this adapter bridges two connection types and pressure classes, the overall system capability must always be based on the lower-rated side and associated components.

Warning: Proper thread identification, flare compatibility, and installation practices are critical—mismatched components, damaged sealing surfaces, or improper torque can result in leaks or catastrophic failure; always verify compatibility with mating components and follow recommended assembly procedures before use.
