Rod-Piston Seal RP1

DESCRIPTION

UThe RP1 seal is a single-acting seal with a symmetrical profile. It is used in hydraulic cylinders to seal piston rods by mounting them in a guide or to seal cylinders by mounting them on the piston in a back-to-back manner.
U-Ring RP1 has obvious advantages: Simple design, inexpensive groove and easy instalation without tools
