![]() ![]() This will help prevent the X-ring from spinning with the rod and staying in the groove. Quad Rings are a unique o-ring with a unique X style profile, doubling the sealing surface if a traditional o-ring. ![]() In rotary seals it is also important to make sure the surface finish of the spinning rod is smoother than the groove. ![]() Due to the symmetrical shape, the X-ring can withstand stresses from multiple. A custom backup must be used if it is required for an application. The X-ring is a symmetrical four lobe seal, with a square fitting cross section. o-rings, caps, ferrules and seals compatible with PerkinElmer, EuroVector, Thermo Fisher Scientific. Since the groove is designed deeper than an O-ring groove, standard backup rings will not work in an application with X-rings. While X-rings do have many advantages in dynamic applications, there are some cautions to using X-rings in dynamic applications. No need to try to find difficult sizes near you, simply order online. We offer metric and standard sizes, large and small diameter, plus no minimum order required on all in stock items. X-rings in rotary seals should also be made of 80 or 90 durometer material. Easily find Viton/FKM, Silicone, EPDM and NBR, and all other types of rubber o-rings. X-rings work best if the rotational speed is kept below 6.5ft/s, the pressure is below 150psi, and temperatures are within -30☌ – 100☌.

Check out our popular line of AS568 o-rings below. Explore Quad-Ring and X-Ring Seals for Reduced Friction Applications Recommended for low speed reciprocating or oscillatory motion if O-Rings twist. Find the best o-ring for your application and order online today. Whatever your o-ring requirements, Ace Seal has got you covered. When designing an X-ring in a rotary gland, just like with O-rings, it is always recommended to design the X-ring as a female seal.

X-rings can also be used in rotating glands, even though reciprocating glands are where their advantages really shine. An X-ring is designed to fit between two parts to fill the gap between them once compressed, whereas an O-ring sits in a groove and compresses when assembled in. This allows for sealing in a much wider range of dimensional variation in both the mating hardware and the X-ring. For one, it is recommended to use the largest possible cross section of X-ring due to the fact that larger cross sections can handle a wider range of tolerance variance. In addition to what was previously mentioned, there are some additional design considerations when creating a reciprocating gland for an X-ring. This is the largest advantage X-rings have compared to O-rings in dynamic applications.
