Screwed Brass Reducing Hex Socket

Screwed Brass Reducing Hex Socket | No. 29 BSP/NPT Reducer for Oil, Fuel & Gas Lines

The Screwed Brass Reducing Hex Socket (Standard Brass No. 29) is a reliable fitting used to join two male threaded components of different sizes. Made from corrosion-resistant brass, this hex socket is built to withstand high-pressure applications in oil, fuel, water, gas, and lubrication systems.

With a robust hexagonal body for easy installation, the reducing socket supports both BSP and NPT thread standards — ensuring compatibility across a wide range of fluid and gas systems. It's a practical solution for system retrofits and upgrades requiring diameter transitions.
