+ O-Rings

Packing Seals & Engineering has been providing O-rings to our customers since 1959. O-rings are much more than a black and round sealing product. They are a critical part of any component and it is important that the correct compound is chosen for YOUR application. Our application engineers welcome the opportunity to help you select the right size and material for YOUR needs.
