871 Gravity Coupler
Civacon's Gravity Couplers are used in the unloading process to connect the 4" API adaptor to 3" or 4" hose connections. One handed operation frees up the operators second hand for maneuvering hoses around. They mate with 4" API RP-1004 tank truck adaptors.
The Gravity Couplers come standard with aluminum bodies and Nitrile seals and hose connections which angle 15° downward for better drainage. If you want safer, faster unloads, you want Civacon Gravity Couplers.
