:: PTFE ENVELOPES ::

Envelope gaskets are produced with pure PTFE with a thickness of 0.5 mm. Envelope gaskets have become popular for their special features that enables them to be is used in severely corrosive services, excellent creep resistance and high deformability. The PTFE makes the envelope gasket suitable for use in the chemical, pharmaceutical and food industry.

PTFE Envelope Gasket is of two types:
1. Slit Type
2. Milled Type

Slit type Envelope: Slit type envelopes can be of different sizes according to the application and the customer's requirements. The gasket outer dimension normally rests within the bolt hole circle and the internal dimension is approximately equal to the nominal internal dimension of pipe. It resists sudden changes of temperature and possesses excellent dielectric characteristics that widens up its scope of application in varied industries. It is tailor made as per requirements of customers.
