Frequently asked questions

What is a straight adaptor for?

It converts the thread size of 1/4 BSP hose fittings so they can be connected to 3/8 BSP HD shank fittings. It consists of a 1/4 BSP threaded male nipple passed through a 3/8 BSP female nut.

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.

How does the straight adaptor differ from the bent version?

This is a straight adaptor for an inline connection, whereas the bent version changes the angle of the connection. Both convert between 3/8 and 1/4 BSP fittings.
