In additional, we have 3 advantages on manufacturing rubber O-rings:
a. We can silk screen the letter on o-ring and never to be erased.
b. The rubber o-rings with colorful Teflon coated is available from us. The o-ring with PTFE coated will have good self-lube and rebound resilience, even at high temperature of 250°C (482°F).
c. Molding the o-rings with parting line at 45°disparting level. This kind of new technician improves the o-rings application so much, when it used as dynamic seals.
