KR Hydraulic Piston Seals
KR is an energized double-acting piston seal installed in IS07425/1 installation grooves, and its applicable pressure range can reach up to 300bar. It consists of a sliding ring made of newly developed polyurethane and an expansion element with square cross section, made of NBR rubber. It has extremely high dynamic and static sealing performance, excellent wear resistance, can maintain low friction operation during the entire working time, and has extremely high anti-extrusion performance. It can be mounted directly on the integral piston as the installation groove complies with the IS07425/1 standard, and the axial installation length is short.
