O-Ring-Loaded U-Cup Seals


Side 1	Side 2	Profile


Rod Installation	Piston Installation

Also known as loaded-lip seals and PolyPaks, an O-ring secures these U-cups to the rod or piston for better sealing performance at lower pressures than unsupported U-cup seals. Because U-cups have a sealing lip on both the inside and outside edges, 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.

High-Stability O-Ring-Loaded U-Cup Seals


Side 1	Side 2	Profile


Rod Installation	Piston Installation

Also known as Type B seals, loaded-lip seals, and PolyPaks, these U-cups are wider than our other O-ring-loaded U-cup seals for better stability. An O-ring secures them to the rod or piston, preventing leaks at low pressure and as the seal wears. Because U-cups have a sealing lip on both the inside and outside edges, 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.
