F02-3303 – The Valterra EZ Coupler system provides a convenient solution for connecting an RV sewer hose to a waste outlet. This three-piece set includes a valve/hose adapter, a hose coupler and a 90-degree universal sewer adapter. Its threaded twist-on connections eliminate the need for hose clamps and help create a secure, leak-resistant connection. The red fittings are made of durable polypropylene and include a drip cap for cleaner storage between uses.
