Frequently asked questions

What sizes does it adapt between?

It adapts between 1/4in and 3/8in (3/8-1/4in), letting a 1/4 BSP hose fitting connect to a 3/8 BSP HD shank fitting.

Which thread direction should I choose?

It is available in left-hand (LH) and right-hand (RH) versions, for fuel gases and inert gases respectively. Select the thread direction that matches your gas.
