Product Overview
Description:
This gasket style is comprised of a polytetrafluoroethlyene, a high molecular weight polymer, commonly referred as PTFE. PTFE is best known for its extreme low coeffient of friction, excellent resistance to high temperatures and corrosive materials. Virgin PTFE boasts a resiliency to virtually all chemicals within the 0-14 pH scale.
When it comes to sealing flanges, whether raised or flat face flanges, there are two type of gasket shapes - ring gaskets and full face gaskets. Ring Gaskets are positioned inside of the flange holts and around the pipe bore. They can also be used within a raised face design, where it sits on the raised surface. Ring Gaskets reuqire less material and less cutting and can be installed without completely dissembling the joint. The disadvantage is the gasket can be harder to align and clamp.
Applications:
Virgin PTFE gasket sheet material is recommended for applications where high-purity materials are required and in processes where contamination or discoloration is unacceptable, such as the food and beverage industries.
Typically Used Within:
1. Food and Beverage processes and industries
2. Essentially within any chemical application
