Calvana (2-Pack 1-1/2" RV Rubber Grommet (12483), RV Water Tank Fittings Holding Tank Fitting - Seals Securely, Black

Good quality and durable. They fit nice and tight, even a bit difficult to install which is a good thing. You know the seal will be tight.

Ok, they work great, though I split one because I didn't figure out the trick until the second one. On the second one, I used the edge of a flat screwdriver to slowly push the edge into the hole as I went around. The first one I was able to fix by gluing the crash with 3M 5200. I used 3M 5200 on the inner groove of each grommet, and on the 1.5 inch ABS pipe that slide into the grommet.

Worked well. A bit stiff and had to muscle in the hole. I almost put a hole through when using a screw driver. I would only recommend using hands to install. I think it will make a good pipe connection in the long run. I used a a flexible sealant inside the groove and on outside of tank to ensure leak free fit. It is a double flanged fitting so it should seal better. If you can't fit the item inside the hole, you can cut off the back flange and glue in place.

good produck

Product was exactly as described, and what I ordered. Shipment was late. Free 1 day prime, doesn't mean when you get enough orders in my zip code then deliver.

dont know, havent used yet but they are strong in the package and are as described

Havr not use yet.

Way too hard of rubber that rips when you deform it to put it into the tank hole. Do not buy!

Good quality, does what ut has to do
