Shop High Pressure Adapters, Male Medium Pressure x Female Medium Pressure

The Medium Pressure Male to Medium Pressure Female OneXtreme Adapters are precision-engineered fittings designed to connect medium pressure coned-and-threaded components in hydraulic, chemical injection, and fluid power systems requiring reliable, leak-free performance. These adapters utilize a 60-degree cone and thread connection to create a secure metal-to-metal seal, making them ideal for applications with working pressures up to 20,000 psi (1379 bar). 


Manufactured from cold worked 316 stainless steel, these fittings provide exceptional strength, corrosion resistance, and long-term durability in harsh and high-cycle operating environments. OneXtreme medium pressure adapters are precision machined for consistent sealing integrity and dimensional accuracy, with special materials available upon request to meet specific application or environmental requirements. 


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