Sioux Chief 9/16" x 3/4" x 3/32" Rubber O-Ring Seal

Sioux Chief 9/16" x 3/4" x 3/32" Rubber O-Ring

Sioux Chief's 9/16" x 3/4" x 3/32" rubber O-ring is a rough-in service and repair part sized for plumbing fitting, valve, and stop applications. Molded from rubber, this O-ring is designed to seat between two mating surfaces and compress slightly under clamping load to help maintain a tight, leak-resistant seal at threaded and compression-style connections. Because O-rings wear, harden, and take a compression set over time, keeping correctly sized replacement stock on hand lets plumbers and contractors restore a proper seal during a service call rather than replacing an entire fitting or valve assembly. This 9/16" x 3/4" x 3/32" size is intended for technicians who need an exact-fit replacement seal for fittings, stops, and valves installed behind the wall or under a fixture, and it is a handy part to keep stocked on the truck for routine rough-in service work.

Key Features

• Trade Size: Manufactured to an exact 9/16" x 3/4" x 3/32" dimension for a precise, drop-in fit in place of the original seal.
• Rubber Construction: Molded from rubber for the flexibility needed to conform to and seal against mating fitting surfaces.
• Compression Seal: Compresses slightly under clamping load to help maintain a leak-resistant seal at threaded and compression-style connections.
• Wear Replacement: Suited for swapping out an original O-ring that has hardened, cracked, or taken a compression set over time.
• Service/Replacement Part: Useful for maintenance and repair of plumbing fittings, valves, and supply stops during rough-in service calls.
• Single-Size Seal: A dedicated 9/16" x 3/4" x 3/32" O-ring rather than a mixed assortment, so the fit matches the original part.
