Product information

Description

Adapter Marcrist 1/2 BSP(M) to 1/4 UNC(M) is a threaded reducer coupling designed to join components with different thread standards. Manufactured for use in fluid, pneumatic and mechanical systems, this male-to-male adapter enables connection between a 1/2" BSP thread and a 1/4" UNC thread, allowing integration of fittings, hoses, valves and adapters that otherwise would be incompatible.

Advantages

The adapter provides a compact solution for converting between BSP and UNC thread types without requiring additional hose assemblies or custom machining. Its male-to-male configuration simplifies installation in confined spaces and reduces the number of connection points. Designed for durability, the coupling maintains thread integrity under standard operating conditions typical for hydraulic, pneumatic and general-purpose mechanical systems.

Suitable for

  • Connecting BSP-threaded hoses, valves or fittings to devices with UNC threads
  • Retrofit and repair work where mixed-thread components must be joined
  • Fluid and pneumatic lines in workshops and industrial installations
  • Mechanical assemblies requiring a male-to-male thread conversion

Key specifications

  • Thread A: 1/2" BSP male
  • Thread B: 1/4" UNC male
  • Function: reducer coupling / male-to-male thread adapter
  • Application: fluid, pneumatic and mechanical connections
  • Typical installation: fittings, hoses, valves and adapters

How to use

Select the adapter when a direct connection between a 1/2" BSP male thread and a 1/4" UNC female thread is required. Ensure mating threads are clean and undamaged, then engage the adapter by hand to align threads before tightening with appropriate wrenches. Use suitable thread sealant or tape when connecting fluid or pneumatic lines to ensure leak-free joints, following the sealant manufacturer's recommendations. Avoid over-tightening to prevent thread deformation.

Usage recommendations

Verify compatibility of materials and pressure ratings of the surrounding system before installation. For pressurized fluid or gas systems, perform a pressure test after fitting and re-check connections periodically as part of routine maintenance.
