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.

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.
