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.

Flexible Leather Strips

Because these cow leather strips are mineral tanned, they are tougher yet more supple than vegetable-tanned leather. Use as seals and gaskets. They have one smooth side and one rough side.

Synthetic Leather

With the look and feel of real leather, this synthetic leather is durable as well as abrasion and stain resistant. It’s often used for finishing, lining, and upholstering. Compared to real leather, which is made using harmful chemicals, this synthetic leather is an eco- and animal-friendly alternative. It also resists bacteria, mold, and odors.
