Hydraulic Seals | Rod Seals | Merkel U-Ring Seal Set 0214 Merkel U-Ring Seal Set 0214 Back-up ring Back-up ring <300 mm Material Back-up ring >300 mm Material Two-piece Merkel seal set comprising an elastomer U-ring with an elastomer sealing edge, fabric reinforcement on the contact area and an active back-up ring. Product description U-Ring Code Cotton fabric Product advantages Other materials like PTFE bronze back-up ring on enquiry. Single-acting rod seal for use in hydraulics and pneumatics. Operating conditions ■■ ■■ ■■ ■■ ■■ ■■ Low friction due to fabric reinforcement Large range of dimensions Protection against extrusion through activated back-up ring Low deformation value (not suitable for sealing systems) Easily installed in non-axial housings From 100 mm diameter Iron and steel technology Presses Marine hydraulics Scrap cutters Injection moulding machines Steel hydraulics engineering Special cylinders * Max. pressure depends on the profile. Medium/­ Temperature HEES (synthetic ester) HEPG (glycol) Mineral greases For Merkel U-Ring Seal Sets 0214, if long strokes are traversed, the max. pressure should only be applied to the last part of the stroke (closing pressure); during the stroke max. 16 MPa.
