19935TS
This is a 4-inch Teflon-encapsulated silicone (Tef-O-Sil) main seat O-ring for Betts internal air emergency valves. It provides a resilient, chemical-resistant seal on the valve's main seat, preventing product leakage when the valve is closed. Commonly used on crude oil and gasoline tank trailers, this O-ring is replaced when it becomes worn, cut, or if the valve fails to seal properly.
Specifically fits Betts 4-inch internal air-operated emergency valves, typically installed on MC/DOT tank trailers for crude, gasoline, and other petroleum products. Not a universal automotive air system part.
