Sealon™ For Oxygen Service

Gasket Materials Approved For Oxygen Service
The following materials have been approved for gaseous and liquid oxygen service by the L’Aid Liquid Laboratory at Blane Mesnil:

FAWN GYLON #3502, a product of Garlock®, available in sheet form 1/16" and 1/8" thick.

SEALON™, a product of Ameraflex Sealing Products, Inc. of Deer Park, TX, available in 1/32", 1/16", and 1/8" thick.

GORE-TEX® JOINT SEALANT, a product of W. L. Gore & Assoc.®, Elkton, MD, available as a tape, strip or round extrusion from a little more than 1/32" to 3/4" thick.

Fawn Gylon® #3502 is a fawn colored sheet material that is primarily PTFE that is filled with an inert solid. The #3502 must be specified as it is specially formulated from materials that are suitable for oxygen. They also sell a Fawn Gylon® #3500 that is not to be used with oxygen. It is fairly expensive and is usually only sold by the 5' x 5' sheet.

Sealon™ is also a filled PTFE material with a salmon color, with properties very similar if not the same as Gylon®. It is said to be less expensive than Gylon® and can be bought and cut to size standard pipe gaskets or smaller than the 4' x 4' or 4' x 8' standard sheet.

Gore-Tex® ribbon is 100% PTFE, white in color, and can be used to seal some flanges and for some valve stem or similar packing applications.

The testing lab warns that if any of these materials are to be used where there is likelihood of adiabatic compression with oxygen, additional tests should be conducted under specific conditions before use is approved.
