Industries where these type of seals have been used to great effect are the food industry, the chemical and petrochemical industries, as well as within pharmaceutical companies. It can be used within a range of applications within these industries also, covering a wide number of issues.

Over the years we have developed our service to provide a high standard of production and supply, with careful monitoring and inspection of all products to ensure that only the highest quality and reliability of product is supplied to our customers.

A PFA o-ring brings with it a number of benefits, these include:

  • A cost effective alternative to traditional, standard PTFE o-ring.
  • High levels of resistance to gas permeability
  • Comes out with top marks in keeping out potentially aggressive chemicals
  • Low friction levels, which promotes longer-term use of applications and equipment due to reduced wear and tear
  • A resistance to issues such as cold flow and compression that has been noted with solid o-rings
  • An adaptive force of sealing application

The encapsulation of a PFA o-ring has the same properties as an FEP, but there are a number of variations. The first difference is that it has greater heat resistance properties when working with applications over a temperature of 205°C. A PFA seal also offers a greater level of resistance to chemicals, keeping out the majority of chemicals, due to a seamless join that is completed through a heat moulding process that is quite advanced in the industry.
