These Hytrel® rings are supplied solid and are normally used to backup 8400 series U-Cups. They are highly extrusion resistant and are compatible with water and petroleum based fluids up to temperatures of 275° F. Unlike PTFE, they can be stretched over larger diameters and will quickly return to their original size. Temperature: -40° to 275°F

2.5 x 2.875 x 0.312 Polyurethane Double Lip Rod U-Cup Inch

The BS series hydraulic rod seal is ideally suited for heavy-duty mobile and stationary service where leakage must be held to an absolute minimum. This unique geometry is highly resistant to side loading and insensitive to pressure spikes. The BS profile reduces or eliminates leakage under severe operating conditions. It also reduces wear and dry run. Rod lubricant is retained in the cavity formed by the secondary lip providing exceptionally low running friction even at low velocities. Sealing performance is outstanding, even at 0 PSI.
Temperature: -50°F to 230°F
