British Thread Adapters Hollow Male Adapters BSP BSPT UNF Thread

Targeting cost-sensitive British-thread connection scenarios, this adapter integrates external thread fastening and hollow fluid passage functions. Manufactured from carbon steel (Q235/45#), it delivers high cost-effectiveness and superior strength for dry/low-corrosion environments, addressing economic connection needs for British-standard interfaces.

• Base Material:
  • Q235: General-purpose grade, cost-effective for low-pressure (≤80bar) and dry scenarios
  • 45# Steel: Quenched-tempered, with tensile strength ≥600MPa, suitable for high-pressure (≤200bar) and impact-prone scenarios

• Thread Standards:
  • Pipe Threads:
    • BSPP (parallel, 55° thread angle): For low-pressure water/gas (requires gaskets)
    • BSPT (tapered, 55° thread angle): Self-sealing for medium-pressure hydraulics
  • Fastening Thread: UNF (fine thread, 60° thread angle): For precision gas circuits (requires face seals)
• Hollow Design: Through-hole diameter matches thread specifications precisely. Roller-burnished inner walls eliminate burrs, ensuring smooth fluid flow (pressure drop ≤8%)

• Cost Leadership: 30-50% cheaper than stainless steel equivalents for mass industrial procurement
• Strength Customization: Quenched 45# steel replaces some alloy steel joints, reducing cost while maintaining strength
• Protection Flexibility: Choose surface treatments to balance cost and service life
