Frequently asked questions

What is the cylinder nut for?

It is a regulator nut, 5/8 BSP, used to connect the regulator to the cylinder. It secures the regulator's bullnose to the bottle.

Why would I need to replace it?

Regulator nuts can become damaged over time from the wear and tear of changing bottles, and that damage can cause leaks at the bullnose. Replacing the nut restores a sound seal.

What size are these nuts?

They are 5/8 BSP, available in left-hand (LH) and right-hand (RH) versions. Choose the thread direction to match your gas.

Which version do I need?

Choose LH or RH to match your gas and regulator; left-hand threads are used for fuel gases and right-hand for oxygen and similar gases.
