Polyurethane scraper

Used in conjunction with rod seals, Repack-S scrapers are optimised for high performance, low-friction service, preventing contaminants entering the hydraulic system. The Repack-S range include polymer and metal scrapers. Danawiper is available as single and double acting scrapers comprising filled PTFE, modified PTFE, Polyurethane, and UHMW-PE and outer energisers: NBR, FKM and EPDM. The scrapers can be used with all hydraulic fluids in the temperature range -50 oC up to + 200 oC. Single material O-rings (HRDA range) use customised profles to provide a double acting scraper effect. Availble in NBR, FKM and polyurethane, the scraper is ideal for hydraulic oils and air, within the temperature range: -30 oC up to +100 oC.
