It features a molded rubber gasket for a liquid-tight seal and may include a pressure-sensitive check valve that allows controlled air exchange to balance tank pressure. Manufactured to GM tolerances, the GT360 cap helps maintain fuel system integrity and the fitment you expect from factory parts.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this fuel cap keep fuel and contaminants out?\u003c\/h3\u003e\n\u003cp\u003eThe GT360 uses a precision-threaded design plus a resilient rubber sealing gasket that compresses against the filler neck to prevent liquid and debris intrusion.
