55.4 x 63.4 x 2.85 Polyurethane Flange Seal Metric

In many cases standard o-rings are not suitable for flange sealing due to marginal conditions such as high pressures or unsuitable surface finish of the flanges. As a result the new polyurethane flange seal profile OV was developed especially for SAE flanges. The particularly low compression set ensures dimensional stability of the seal over a large temperature range. Its high extrusion resistance prevents gap extrusion even if the flanges breathe under pressure. Due to the good abrasion resistance less gland preparation is necessary on the surface finish of the sealing area of the flange. The frequently occuring pumping phenomenon of close fitting o-rings is prevented by the shape of the new flange seal profile OV.
