🔁 Valterra F02-2103 Flexible Coupler - 3" for Enhanced Pipe Connection Efficiency Review

Does not fit Valera's 3" drain valve or my 3" tank drain. I assumed it was meant to bypass the drain valve but it is exactly the same size so it's unsuitable for that I would have to glue an internal hard coupling to the tank and valve just to use this which almost defeats the purpose.

Replaced 17 year old flex couplings on 2004 Winnebago litter bins. The old clutches cracked and leaked after I installed the new bypass valves. Tip: If you plan to install new bleed valves, disconnect these couplings to allow for more piping and flange movement and to avoid damaging the couplings. This greatly simplifies valve installation. Disconnecting the valve flange from the coupling also makes it easier to screw in the new valve.

The 3 inch fitting on our gray Navion RV tank started to leak. This 3" jack plug fits perfectly and seems high quality. When I removed the original plug you could see why it was leaking. Looks like the Winnebago overtightened the screw terminal and popped into the rubber. (See 2. Image for split size!) I wasn't sure if it was the right length or not but compared to the original and after fitting it is the perfect size Highly recommended if you need to replace the rubber connector.
