E-Z Coupler RV Sewer kits have the convenience of RV standard bayonet fittings. A quick twist is all that's needed for simple and secure RV-to-sewer connections. Now changing hose lengths can be made without removing and reattaching any fittings! The kits include the new EZ Coupler 90 degree bayonet sewer fitting and 10 feet of hose. The 20' deluxe kit has two 10' hoses. Both kits feature factory installed standard bayonet fittings including the new rotating fitting to ensure your hose lays flat after twisting fittings into place.
