X-Ring Low Friction Seal

A4 Engineers offers X-Ring Low Friction Seal in four lobed design. These X-quadrings provide twice the sealing surface of a standard O-ring. Because of the double-sealing action, fewer squeezes are required to maintain an effective seal. The reduction in squeeze means less friction and wear which will increase seal life and lower maintenance costs. Unlike an O-ring where the parting line is found on the sealing surface, the X-ring seals' parting line is located between the lobes away from the sealing surface. The four-lobed configuration of the X-ring resists distortion called "Spiral Twist" that is sometimes encountered by an O-ring. The grooves on the inside and outside diameter of the X-ring retain lubricant thereby lowering friction and extending packing life. The X-ring fits into grooves designed for an O-ring so there should be limited problems retrofitting the seal. The size range includes ASTM, BS, ISO and IS standards. A4 Engineers is a distinguished manufacturer and exporter of rubber and PTFE components. The comprehensive range includes gaskets, PTFE tubings and gaskets, sanitary gaskets, tri-clamp sanitary gaskets, O-rings, silicone sponge gaskets, hydraulic seals, pneumatic seals, rubber mouldings and extrusions and others.
