PTFE Envelope Gasket

PTFE Envelope Gasket is a Non-metallic Gasket, Generally Composed of Two Parts: the Envelope and Insert. the Envelope Layer Mainly Plays a Role in Corrosion Resistance and Usually Made of Polytetrafluoroethylene. the Insert (Filler) is a Non-metallic Sealing Material with or Without a Metal Reinforcement Layer with Good Elasticity.

The Envelope Gasket is Divided into V Type, U Type, and L Type According to the Different Inner Core Structures. Some Containers, Pipes, and Valves in the Petroleum, Chemical, Pharmaceutical and Food Industries Are Often Connected with PTFE Gaskets to Ensure Clean Materials. PTFE Envelope Gaskets Are Widely Used in the Sealing of Various Strong Acids, Strong Alkalis, Strong Oxidation, Chlorine and Non-contaminated Media

Temperature

Up to +250oc (depending on the Gasket Material Used).

Applications

Glass-lined Pipe Systems, Distillation Columns and

Reactor Vessels Where Non-contamination is Essential.

Type A

Item No.: JSG-PT131

Made in the Material Forming a "V" Shape Space for One Filler.

The point of the "V" Protrudes Slightly into the Pipe Causing Slight Flow Turbulence.

Type B & C

Item No.: JSG-PT32 & JSG-PT33

Material is Milled or Machined out Between Leaves to Form a U or Square Shaped Space for the Filler.

the Filler is Flush with the Envelope Which Is Flush with the Pipe, Permitting Free Flow.

Gasket Material Filler

Non-Asbestos, EPDM, Reinforced Graphite, Etc.
