## Summary description

Thread adapter from Marcrist that converts a 1/2"x20 UNF female thread to a 1/2" BSP male thread. Designed for joining tools, hoses or fittings with differing thread standards, it ensures mechanical connection between UNF and BSP systems. Suitable for workshop, industrial and maintenance use where compatible sealing and proper thread engagement are required.

## Long description

Marcrist adapter 1/2"x20 UNF female to 1/2" BSP male provides a mechanical transition between two common thread standards. It enables connection of tools, hoses or fittings with a 1/2"x20 UNF female interface to equipment using a 1/2" BSP male thread, maintaining correct thread engagement and sealing when used with appropriate sealing material or gasket. The adapter is intended for workshop, industrial and maintenance environments where mixed-thread systems must be joined.
Advantages
The adapter offers a compact and durable solution for joining UNF and BSP components without modifying existing parts. Its precise thread cutting ensures consistent engagement and reduces the risk of cross-threading. The simple, single-piece design minimizes leak points and supports repeated assembly and disassembly. It is compatible with common sealing methods for threaded connections, allowing reliable mechanical and fluid-tight joints when installed correctly.
Suitable for
Connecting pneumatic or hydraulic hoses with different thread standards
Adapting hand tools or power-tool fittings to workshop equipment
Temporary or permanent joins in maintenance and repair tasks
Prototyping and test setups that combine UNF and BSP components
Key specifications
Thread conversion: from 1/2"x20 UNF (female) to 1/2" BSP (male)
Material: metal suitable for mechanical and fluid connections
Form factor: single-piece threaded adapter
Intended environments: workshop, industrial, maintenance
How to use
Ensure both mating threads are clean and free of debris or damage. Apply an appropriate thread sealant, tape, or gasket according to the fluid type and operating pressure; then hand-start the adapter into the UNF female thread to avoid cross-threading. Tighten using an appropriate wrench until a secure fit is achieved without over-torquing. Verify the connection for leaks under low pressure before placing into full service, and re-check thread engagement after initial operation.
Usage recommendations
Use thread sealants compatible with the working fluid and temperature. Do not exceed the pressure or temperature limits of the connected components. Inspect threads regularly for wear or damage, and replace the adapter if any deformation or excessive corrosion is observed.
