Frequently asked questions

What does a flame trap do?

It is a vital item of gas safety equipment that helps prevent dangerous back-feeding of gases. It must be used at the torch end of a hose.

Where should the flame trap be fitted?

Fit it at the torch end of the hose, fastened inside the hose using hose clips. This position is important for it to work as intended.

Which thread direction should I choose?

It is available in left-hand and right-hand versions. Match the thread direction to your gas line and equipment; left-hand threads are used for fuel gases and right-hand for oxygen and similar gases.

Which sizes are available?

It comes in 1/4-1/4in, 3/8-1/4in, 3/8-3/8in and 3/8-5/16in size combinations, so you can match or convert between common hose fittings.

How is it secured?

It fastens inside the hose using hose clips, which are supplied separately. The clips crimp over the hose to hold it firmly and create a gas-tight seal.
