Why Choose the 2" Uniseal Grommet?
Traditional threaded tank fittings can crack, leak, or fail over time due to vibration and thermal expansion in RV applications. The 2" Uniseal Grommet solves these problems with a flexible, compression-based seal that adapts to movement and temperature changes. Unlike spin-weld fittings that require specialized equipment, Uniseals install in minutes with just a drill and hole saw. The white color blends seamlessly with most RV tanks while providing UV resistance for long-term durability. Whether you're building a custom fresh water system, repairing a holding tank, or upgrading your RV plumbing, this grommet delivers professional-grade performance without the professional installation cost.

Frequently Asked Questions
How do I install a 2" Uniseal grommet in my RV tank?
Installation is simple and requires no special tools beyond a drill and 3" hole saw. Drill a clean 3" hole in your tank wall, insert the Uniseal grommet from the outside, then push your 2" PVC Schedule 40 pipe through the grommet using soapy water as lubricant. The compression seal is immediate and watertight.
Is this compatible with my 2" PVC pipe?
Yes, this grommet is specifically designed for 2" PVC Schedule 40 pipe, which has an outer diameter of 2.375". It will NOT fit 2" nominal pipe with different wall thicknesses or non-standard dimensions. Always verify your pipe is Schedule 40 before ordering.
What's the maximum tank wall thickness this grommet supports?
The 2" Uniseal grommet works with tank walls up to 3/8" (9mm) thick. This covers most RV holding tanks, fresh water tanks, and polyethylene storage tanks. For thicker walls, contact us for alternative fitting solutions.
Do I need to use sealant or adhesive with this grommet?
No adhesives, sealants, or clamps are required. The Uniseal creates a watertight compression seal through its flexible design. Using soapy water during installation helps the pipe slide through easily, but the seal itself requires no additional products.
Can I remove and reuse this grommet if I need to replace the pipe?
Yes, one of the major advantages of Uniseal grommets is that they're reusable. You can pull the pipe out and insert a new one without damaging the grommet or needing to replace it, making repairs and modifications much easier than permanent fittings.
Will this work with my black water or grey water holding tank?
Absolutely. Uniseal grommets are chemical-resistant and work perfectly with fresh water, grey water, and black water applications. The white color is UV-resistant and won't degrade from exposure to tank chemicals or sunlight.
