Profile: Clifford Springs Ltd. specializes in the manufacture of seal energizing springs. We manufacture a complete range of seal energizing products using CNC machines and supply to the seal industry. Our single height canted coil springs are used for their load characteristics. They are manufactured utilizing Hastelloy, Elgiloy, stainless steel and carbon based materials. Our peek springs are used in the high performance S seals as an anti extrusion device, replacing the Inconel or stainless steel spring. One of the characteristic of this polymer spring is as the seal wears and the spring comes into contact with the shaft the spring does not score the shaft. The peek spring when used in conjunction with a peek seal will also stop the issues of using some metals together and they also give a stable seal when used in temperature.
