Mantek’s premium quality O-ring cords are extruded from low compression set compounds. Low compression set is one of the most desirable physical properties when selecting a material for seals. Seal materials with a high compression set can fail after only a few hours of use. Our cords were developed for their low compression set and suitability for the method of manufacture used. The manufacturing system employs a ‘closed loop’ control system where laser micrometers feed-back to a computer which controls the extruder.
