X-Ring Seals

X-Rings Available in Buna-N, FKM, EPDM  or Custom Compounds

The four-lobed design with a specially developed sealing profile of these seals provides twice the sealing surface of ordinary O-rings. The four-lobed design not only provides lower fiction than an O-ring, but also, due to its square cross section, it resists spiral twist. X-Rings are available in a wide range of elastomer materials for both standard and special applications. Their dimensions are specified with the inside diameter "d1" and the cross-section "W." X-Rings are supplied to the American Standard AS-568A and are completely interchangeable with O-rings in these sizes. They can be used in a variety of static and dynamic sealing applications including rotary, reciprocating or oscillating motion.

Features:

  • There are two sealing surfaces to give a positive seal with less friction. Due to an improved pressure profile over X-Ring Seal cross-section, a high sealing effect is achieved.
  • The recessed mold parting line provides no flash or parting line on the surface of the seal and ensures "zero leakage." What's more, a lubricant reservoir formed between the sealing lips improves performance at start-up.
  • The X cross-section resists spiral twisting and extrusion. Due to its special profile, the seal does not tend to twist in the groove during reciprocating movement
  • Twice the sealing surface means less radial squeeze is needed to create an effective seal resulting in less friction, less wear and longer service life.

The O-Ring Store LLC, We make getting o-rings easy!!

The O-Ring Store LLC began in 2007 supplying O-Rings primarily to the large Paintball industry including our own shop and field. Over the last decade we have been fortunate enough to supply O-Rings and Hydraulic Seals to tens of thousands of customers in every industry. The crew is comprised of friends and family that work hard for each other and everyone that relies us to be their O-Ring supplier. Outside a select few, the big O-Ring brand service levels have became counterproductive to real customer service so we have been developing a network of partners with unique capabilities that allow us to provide a multitude of products, materials, and production capabilities to ensure our customers receive the best product and service options possible. This has allowed us our own line of branded materials which utilize the same raw polymers and contract manufacturers as the big brands, but without the overhead, complications and attitudes that result in high prices in lead times. Currently we stock over 50,000,000 O-Rings and Seals . Due to customer requests and to better our processes, we have begun the process to be ISO 9001 Certified in the first quarter 2020. It has been and will continue to be a wonderful journey with challenges and rewards. Thank you for your support and confidence.
