X Rings / Four Lobed Rings


X Rings also known as four Lobed rings are used in a variety of static & dynamic sealing applications.

The four lobed design provides twice the sealing surface in comparison to a standard
O-rings. The double seal action requires less squeeze reducing friction & improving seal life.

outperform standard o rings in rotary seal applications. The four lobed configuration avoids spiral twisting.

It allows the use of a more narrow groove width than a standard o ring groove but works fine even in a standard O-Ring groove.

Construction Materials

X Rings Four Lobed are Manufactured from over 15 different Polymers which include, Nitrile (NBR), Fluorocarbon (Viton®), Silicon (VMQ), Fluorosilicone (FVMQ), Polyurethane, PTFE (Teflon®), Natural Rubber (NR), Ethylene Propylene (EPDM), Hydrogenated Nitrile Rubber (H-NBR), Carboxylated Nitrile Rubber(X-NBR), Styrene Butadiene Rubber (SBR), Perfluoroelastomer (FFKM), Chloroprene (Neoprene®).
