Quad Lobe X-Ring Seals

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.

O-Rings and Seals are very important to us and as part of our effort to "Make getting o-rings easy!", we have improved several areas of our business for 2020 and beyond. We needed more space for our expanding inventory so we added and additional 5,000 square foot warehouse space. We added several key people, Gary in our sales department, Savanna and Macey to our warehouse crew, Julian in our kit department and Steven to assist in the O-Ring Vulcanizing department. ISO Certification is underway and Melissa should have it completed early in 2020. Shipping department is reducing costs and increasing service by adding a defualt 2-Day Air Shipping Service for as low as $6.99. We make getting o-rings easy!

As a family-owned business we enter our 13th year of business in 2020 with great excitement. We have added additional inventory, product offering and great new staff members that not only make it easier to get o-rings, but for us it makes it great to come to work. Our plan is to continue adding new product and services to enhance our current offerings. Adding The O-Ring Store LLC as your O-Ring and seal supplier will improve your ability to repair or build your products and service. We know how hard it is just to get the product you need, by having a shop account and registering you will receive the appropriate business discounts, permanent cart, address book, and order history.

A sincere "Thank You" from my family and my work family, Marty C Frostad, GM and Owner.
