HBVC Series Vapor Caps – Protect Your Vapor Recovery System from Dust, Debris, and Leakage

Available in orange or black, the caps feature a lockable lever to prevent unauthorized access and ensure operational safety. All models are compatible with standard 4-inch male Camlock connections, and the push-pull locking mechanism allows for quick and easy installation or removal, saving time during routine operations.
