Before buying, measure the current part with calipers and match it against the specification table: inner diameter (ID) at the shaft contact surface, outer diameter (OD) at the housing seat, and thickness (height) measured perpendicular to these two diameters. If you're unsure about the size or lip type, send the old part's code or a photo of it to IranSeal's sales team so they can find the exact match.
The K76 spiral guide is designed for use on both rods and pistons in hydraulic applications.
