Rod Installation	Piston Installation

In addition to providing excellent sealing performance at low pressure, these seals withstand a wider range of temperatures and chemicals than U-cup seals. They’re also known as spring-energized seals. They have a sealing lip on both the inside and outside edges, so they 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.

Graphite Filled—Graphite-filled seals have greater wear resistance and strength than seals without a filler.

PTFE—PTFE seals withstand a wider range of temperatures and chemicals than UHMW seals.

UHMW Polyethylene—UHMW seals are good for sealing out water and hydraulic fluid in environments where chemicals and high temperatures are not a concern.

PTFE Stackable V-Ring Packing Seals


Male and Female Adapters Stacked with Five V-Rings	Profile

Made of PTFE, these V-ring packing seals have excellent chemical resistance and withstand a wide temperature range of -110° F to 500° F. Stack as many V-rings as you need to fill grooves in valves, pumps, and cylinders.

Begin with a male and female adapter, then add V-rings between them to fill the space. Each V-ring adds to the sealing force; the female adapter also has a sealing edge. For a complete seal, you need male and female adapters (sold together) and at least one V-ring (sold in packs of 5).

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

Cartridge Mechanical Shaft Seals

Install these seals faster and with less technical expertise than other mechanical shaft seals that come in two pieces. They come with their seal and seat already assembled. All have a carbon washer that is self-lubricating. However, this means their washer is too soft to be used with abrasive liquids and liquids with harsh additives.

Fluoroelastomer Diaphragm—Seals with a fluoroelastomer diaphragm can be used with a wider range of chemicals than EPDM diaphragms, including benzene, butyl alcohol, and fuels.

EPDM Diaphragm—Seals with an EPDM diaphragm won’t break down from exposure to water and steam. However, they are for use with fewer chemicals.
