Tri-Clamp Envelope Gaskets PTFE/EPDM


The envelope gasket has a Teflon exterior and an EPDM interior. These gaskets give you the chemical resistance of PTFE (Teflon) and the sealing characteristics of EPDM.  They are commonly used in combination with swivel joint tri-clamps.  Sizes 1" through 4" are listed but we can special order sizes for you up to 12".
