Description

The vapor dust cap is installed on the oil vapor recovery adaptor of tanker trucks. It can serve as

a secondary seal to prevent oil vapor leakage and stop dust and debris from entering the valve.

The evenly tensioned sealing gasket is compressed to ensure a complete and tight seal between

connections. It has high load-bearing capacity and corrosion resistance, thereby extending its service

life. It is suitable for 4-inch grooved adapter valves that meet the API 1004 standard. The cam structure

makes the opening and closing of the cover quick and convenient. The orange-red color helps prevent misuse.
