Doc. 138/15 PTFE Used as a Sealant for Cylinder/Valve Connections

The most common method of ensuring a gas-tight seal at the cylinder valve/neck interface, is to use polytetrafluoroethylene (PTFE) tape.

This EIGA publication describes the use of such tape whilst outlining other potential sealant materials.
This publication covers the gas-tight sealing of conical threads used on gas cylinders and cylinder valves through the use of PTFE and gives practical guidance on how to achieve a gas tight connection on the cylinder valve/gas cylinder interface.
It is intended for those who are involved in the selection and application of sealing materials for cylinder valve/neck interface.
