Frequently Asked Questions
What hole saw size do I need for the U050-W Uniseal Grommet?
You'll need a 1-1/4" (32mm) hole saw to cut the correct opening in your tank for the U050-W grommet. After cutting, smooth any rough edges for the best seal.
Is the U050-W compatible with PVC Schedule 80 pipe?
The U050-W is designed and rated for PVC Schedule 40 pipe. While it may physically fit Schedule 80 pipe (which has the same OD), we recommend using it as specified with Schedule 40 for optimal sealing performance.
How do I install a Uniseal grommet?
Cut a 1-1/4" hole in your tank wall, smooth the edges, insert the grommet into the hole, then push your PVC pipe through the grommet. The compression seal forms automatically — no glue or sealant needed. Measure twice before cutting!
What is the maximum tank wall thickness for the U050-W?
The U050-W Uniseal Grommet accommodates tank walls up to 3/8" (9mm) thick, which covers the vast majority of RV polyethylene holding tanks.
Can I use this grommet for fresh water and waste water tanks?
Yes — the U050-W is suitable for use with both fresh water and waste/holding tanks. The UV-resistant thermoplastic elastomer material is safe for potable water applications.
