SPEC SHEET

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

The BT series rod seal is a premium hydraulic 90A polyurethane seal. Using Parker's® 4300 proprietary compound, this profile provides shock load resistance and increased sealing performance, even at zero pressure and with one of the highest temperature ranges available in a polyurethane seal. A knife trimmed beveled sealing lip does an excellent job wiping excess fluids from the rod while a secondary sealing lip, located at the base, ensures a stable fit in the gland while providing an enhanced seal.

UNP series urethane u-cups are non-symmetrical in design and are meant only to be used for reciprocating hydraulic piston applications. They are manufactured slightly smaller in diameter than nominal dimensions. This ensures a tight fit when installed in the groove. Good stability and decreased heel drag, resulting in lower friction, are the prime features of this seal.
