Coated O-Rings are standard elastomer O-rings that are specially coated with a thin, uniform layer of low-friction or protective material to enhance their performance and service life. The coating improves lubricity, reduces installation force, and minimizes friction during dynamic or sliding applications, helping to prevent twisting, tearing, or damage during assembly.

In addition to easing installation, the coating provides improved resistance to wear, abrasion, and chemical attack, and can act as a barrier against sticking, extrusion, or degradation caused by aggressive media. Coated O-Rings are widely used in automotive, hydraulic, pneumatic, oil & gas, chemical processing, and industrial equipment applications where smooth operation, reliable sealing, and extended durability are critical.
