This part works just fine. E-Trailer has been a good source for the occasional trailer part when I need something.

Ive been camping all my life.. From childhood camping with my parents . I enjoyed camping so much i now live in a huge 5th wheel camper. Ive tried numerous rv sewer attachments and after a year they start to wear and leak especially during dumping your rv grey and black tanks. Trust me you do not wont any leakage during this process.. After owning this coupler for a year and dumping waste never has leaked one single time. Awesome product

The is the best fitting to get if you have an older rig. My 3" hose only fits in the rear bumper. I carry this fitting along with the drain receptacle in the storage compartment and screw them on when I hook up. George charged a fair price and the shipping was reasonably fast.
by:
These fittings actually work the way they're supposed to. Much higher quality than most other sewer hose fittings. Very easy to install and they seal up tightly without clamps. Shipment from etrailer was prompt and their price was much better than the average rv ripoff store.
