180966 - Miller 180966 Quad-Ring Seal .926 ID x .070 CS (5-Pack)

Genuine Miller Quad-Ring Sealing Solution

The Miller 180966 O-Ring is a specialized Quad-ring (also known as an X-ring) designed for specific sealing applications within Miller welding equipment. Unlike traditional circular O-rings, this component features a four-lobed cross-section. This unique profile provides two sealing surfaces per side, effectively doubling the sealing reliability compared to standard O-rings. With an Inner Diameter (ID) of .926 inches and a Cross Section (CS) of .070 inches, this seal is precision-engineered to fit tight tolerances, ensuring leak-free operation in your industrial machinery.

Manufactured with a 70 Durometer hardness, this seal strikes the perfect balance between flexibility and durability. It is tough enough to resist extrusion under pressure while remaining pliable enough to conform to mating surfaces. The Quad-ring design is particularly advantageous in dynamic applications where standard O-rings might be prone to rolling or twisting in the groove, which can lead to premature failure. By using this genuine Miller part, you ensure that the material composition is compatible with the fluids or gases used in your specific welding system.

This product is sold as a package of 5, providing excellent value for maintenance teams and repair technicians. Having spares on hand is critical for minimizing downtime during scheduled service or unexpected repairs. Whether you are sealing coolant lines, gas pathways, or hydraulic components within your power source, the Miller 180966 offers the OEM quality required to maintain factory performance standards.
