Parco, Inc.

Founded in 1941, Parco was the first manufacturer to specialize in O-rings, still one of our primary products. Today, Parco has four modern facilities manufacturing O-rings, custom-molded elastomeric seals, rubber-to-metal bonded parts, and machined metal parts. Our 154,000 square-foot facility in Ontario, California is one of the largest plants in the world making molded rubber seals. Our three other facilities in Texas and Louisiana specialize in complex custom-molded elastomeric products, machined metal parts, and machined plastics.
