Midwest Sealing Products is an authorized fabricator and distributor of Garlock Sealing Technologies Gylon materials.
Gylon is one of the most popular flat PTFE gasketing materials available, and comes in a wide range of styles. All Gylon styles have the following characteristics:
- Color-coded material for quick and easy identification of style
- Intended to stand up against severe chemical service
- Excellent sealability, leading to a reduction in media loss
- Reduced creep
Creep is one of the common problems that has to be dealt with when using PTFE materials. However, in the case of Gylon, those concerns are significantly decreased. The method in which Gylon is produced works to limit the creep relaxation problems that you may have dealt with when using other products.
