The requirement for low coefficients of friction, less than .08, temperatures ranging from -300F to +550F, pressures in excess of 5000 psi, the need to seal a corrosive acid …..These are the typical kinds of factors that tell you that an elastomeric seal probably wont fit your application.
Seal Science Teflon® Seals and Seal Science Perflex perfluoroelastomer are often the answer. Possibly something as simple as a Teflon O-Ring, or a Teflon compound cap to protect the elastomer will do. Or maybe, spring energized Teflon U-Cups, like those in our Polyspring line might be needed. Many of the possible solutions can be found in our Polyking catalog. Whatever the appropriate choice may be, our Teflon engineers will be able to quickly offer you a recommendation and a quote. Check our how competitive we can be!
