PRODUCTS WE OFFER
O-ring is the most common type of rubber sealing. Despite the comparatively straightforward design of groves, engineers need to pay close attention to some well-established design rules to optimize the overall performance. Ascend Sealing stocks most of the popular standard O-ring sizes, including SAE AS-568, BSI BS 1806, and JIS B 2401. We also offer Metric O-rings and custom-sized O-rings upon request. Please contact us for custom sizes not listed on the standard size chart.
X-rings, named according to their shape, are an alternative to O-rings. Unlike the curved and sleek feature of O-rings, X-rings have two separated sealing surfaces, making subtle defects less detrimental. Furthermore, given the shape of X-rings’ cross section, they have better resistance to coiled twisting with periodical pressure. Given the above features, X-rings achieve superior results than O-rings do in certain conditions. Ascend Sealing offers standard AS-568 size X-rings. If the X-ring you are looking for is not listed in the standard X-ring size chart, please contact us for more information.
Backup rings are designed to reduce the risk of extrusion in high pressure sealing applications. They reduce the expensive metal works on the groove and improve the alignment for mating components. Ascend Sealing offers a wide variety of materials for backup rings. Please contact us for more information.
ED ring or ED seal is a profile ring in accordance with DIN 3869. ED rings are axially static seals that are used in fastener applications with threaded elements. While tightening the screw,ED ring converts the tightening force into inward radial compression, achieving the sealing function. ED ring is widely used in many industrial applications, including construction machinery, injection molding machinery, hydraulic valves and fittings. Ascend Sealing offers a Nitrile/NBR Rubber for general purpose applications. We also provide Fluoroelastomers (FKM) for higher temperature applications and harsh chemical applications.
