F02-3102 by Valterra is a red EZ Coupler connector designed to join two RV sewer hoses together and extend their reach when connecting to a campground sewer outlet. Its self-threading design allows for quick twist-on installation without hose clamps. The connector is compatible with 3-inch sewer hoses designed for the EZ Coupler threaded system. It is a practical accessory for recreational vehicle waste-water management and can be stored with your sewer hose when not in use.
