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.

Toilet Sealing Rings

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

For Floor-Mount Toilets


Wax	Wax with Flange

Wax—Wax rings are the most common, but they can only be used once. If you change the position of the toilet 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.

Clean-Away Protective Coatings for Metal


Aerosol Can	Jug

Protect metal parts from corrosion. Also known as rust-inhibiting film, these coatings can be removed with a simple degreaser or mineral spirits.

Wax—Wax coatings meet MIL-C-16173 for corrosion-resistant compounds that dry to thin, easily removable films.

Jug—Coatings in a jug can be dipped, brushed, or sprayed.

MIL-C-16173 Grade 2—Grade 2 coatings dry to a slightly tacky, self-healing film that lubricates as it protects.

MIL-C-16173 Grade 4—Grade 4 coatings dry to a nontacky finish that’s suitable for environments exposed to high humidity and chemicals.

Cannot Be Sold To—Coatings that cannot be sold to the regions listed are restricted by product labeling requirements or exceed local regulatory limits on VOCs (volatile organic compounds).

Low-Odor Abrasion-Resistant Clean-Away Protective Coatings for Metal

These low-odor coatings form a waxy film similar to lube oil, so parts can remain coated for assembly. They can be dipped, brushed, or sprayed onto surfaces and then removed with an alkaline cleaner.
