China Omk-Mr OE Series NBR FKM+PTFE Glyd Ring Hydraulic Piston Seal Ring

Description
The NO profiles hydaulic seal ring are double acting composite piston seals composed of a filled PTFE friction ring and pre-tightened rubber O-ring. They can be assembled in grooves according to standard ISO 7425/1. Option of connecting the seal to 1 or 2 back-up rings.
Design standard
The series is in conformity with ISO 7425/I, GB/T15242.1-94 and GB/T15242.3-94. Reference can also be made to Busak+Shamba's GS55044 series, Merkel's OMK-MR,Trelleborg's YG4 series, AS's YB series and Parker's OE series.
