Envelope Type III PTFE Gasket with FIllers 

Overview 

Type III envelope gaskets are the perfect solution if you need the chemical resistance of PTFE and the "squish" or compression of elastomers like Viton or EPDM.

 

To determine which insert is right for you, we suggest using the temperature range of the insert. They are as follows: 

EPDM: -30 F to 300F (-34 C to 149 C)

FKM: -30 F to 400F (-34 C to 204 C)
