Teflon® Encapsulated O Rings
Solid Ptfe
  • Solid PTFE O Rings enjoy true chemical inertness. Ptfe is unaffected by all known chemicals but this is its only advantage. Ptfe sufferers badly from 'cold flow' and as such is really not suitable for use as a compression seal.

PTFE Coated
  • O-Rings coated with acrylic or latex suspended Ptfe dispersion do give some low friction properties but the coating is very easily removed. The method of manufacture is extremely low cost but coated O Rings offer no chemical protection.
