Urinal Sealing Rings

Seal urinals to their mounting flanges—these rings create a watertight, odor-free barrier.

For Wall-Mount Urinals

Wax

Wax—Wax rings are the most common, but they can only be used once. If you change the position of the urinal after setting it down, the ring will become deformed.

High-Pressure Leather Stackable V-Ring Packing Seals


Five V-Rings Stacked		Profile

These leather V-ring packing seals handle over twice the pressure as PTFE. Leather is tough, pliable, and wear resistant, so it flexes to fit uneven surfaces and fill voids. Stack as many V-rings as you need to fill grooves in valves, pumps, and cylinders—each additional ring adds to the sealing force.

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

High-Pressure U-Cup Seals


Side 1	Side 2	Profile


Rod Installation	Piston Installation

Rated for pressure up to 10,000 psi, these leather U-cups handle over 80 times more pressure than our Buna-N U-cups. Leather is tough, pliable, and wear resistant, so it flexes to fit uneven surfaces and fill voids. U-cups can be used for rod and piston sealing. Pistons require two seals—install one facing in each direction.

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Water- and Salt-Water-Resistant Packing Seals

Made of flax fiber, these seals are excellent for marine applications since they resist salt water. Cut them to size with a knife; then pack them into place.
