Jacket Materials:

Ultra Seal offers a wide choice of seal jacket materials, mainly based on PTFE resins.

PTFE is resistant to most chemicals except chlorine trifluoride/fluorine gas at high temperatures and molten alkali metals. However, as many sealing applications use filled PTFE resins to improve performance, care should be taken that the filler will not be attacked by the sealed medium.

Stainless Steel and NACE approved springs are available as is a range of elastomeric energizers.

When using elastomers, consideration of temperature/chemical compatibility and life should be accounted for.

At temperatures below -40. C. PTFE and many other jacket materials will harden and shrink. This feature imposes higher loads on the energizer and may compromise sealing efficiency. Face seals (Axial Seals) are less affected than Radial Seals but we recommend our technical department be consulted for seal designs working at -40 deg. C and below.
