Standard - Height and cross section are equal, thus giving a square seal. Utilizes type 'D' lip. Typical Part Number U25-2.50 |
 |
Deep - Utilizes the same 'D' lip, but the seal height is greater than the cross section, thus giving a rectangular shape. Typical Part Number U25-2.50-37D |
 |
Type SQB - Same dimensions as the Standard seal. Beveled lip design provides better film breaking. Utilizes type 'B' lip. Typical Part Number U25-2.50-SQB |
 |
Type B - Same dimensions as the Deep seal. Beveled lip design provides better film breaking. Utilizes type 'B' lip. Typical Part Number U25-2.50-37B |
Piston cups are constructed of rubberized fabric. Cups with no hole are center punched.
NOTE: If Product number ends in 'ED' the piston cups are specially sized for use in EDBRO Cylinders.

Our premium single-acting polyurethane rod seal incorporates an NBR energizer to seal at low pressures. The twin lip design provides stability and friction-reducing lube retention for dry rod sealing, and the included hard acetal backup ring resists extrusion. MRTUB is capable of pressures up to 10,000 psi in approved applications. Please consult Hercules Engineering for pressures above 6,000 psi.
One Piece Double Acting Piston Cups
This complete piston cup with a simple, one-piece construction serves the same purpose as a multi-assembly unit and is more economical with easy maintenance, dependability and long life. The unique piston cup consists of homogeneous rubber bonded to a zinc coated steel plate. The center hole may be enlarged to accommodate larger piston rods. Recommended for pneumatic and low-pressure hydraulic applications.
