X4H04B30 : OneXtreme Adapter, 0.25 (1/4") Male HP x 0.25 (1/4") Male BSP, 30,000psi

The High Pressure Male to BSP Male OneXtreme Adapters are precision-engineered conversion fittings designed to connect coned-and-threaded high pressure systems to BSPP (British Standard Parallel Pipe) connections in demanding hydraulic, chemical injection, and fluid power applications. The high pressure side utilizes a 60-degree cone and thread connection to create a reliable metal-to-metal seal for applications up to 60,000 psi (4136 bar), while the BSPP side features straight (parallel) threads that seal via a cone, gasket, O-ring, or dowty seal depending on the mating configuration, and may also include an external cone.

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, sealing method selection, and installation practices are critical—mismatched threads, damaged sealing surfaces, or improper assembly can result in leaks or catastrophic failure; always verify compatibility with mating components and follow recommended installation procedures before use.
