Williams Comfort Products 7-1C Drive O-ring

Product Description

The WILLIAMS COMFORT PRODUCTS 7-1C is a replacement O-ring sized for a 1-inch drive application with an outer diameter of 2-7/8 inches. O-rings in this category provide a compressible seal between mating components, preventing fluid or gas leakage at connection points. This part is sold individually and is suited for use by licensed plumbers, HVAC technicians, and mechanical contractors performing maintenance or repair on compatible drive fittings and assemblies. At 0.02 pounds, the 7-1C is a lightweight, single-piece consumable typically kept as a standard service item on the work truck.

This O-ring is used in applications where a 1-inch drive fitting requires a sealing element. It is commonly installed during routine maintenance, leak repair, or component replacement on mechanical systems that utilize drive-style connections. The 2-7/8-inch diameter makes it appropriate for standard-sized drive fittings found in residential and light commercial service environments. Technicians performing teardowns and reassembly on relevant equipment should replace this O-ring any time the connection is broken to ensure a proper seal on reassembly.
