Danco 9D00010712 Rubber O-ring Kit Medium

Product Description

The DANCO 9D00010712 is a medium rubber O-ring kit designed for sealing applications in residential and light commercial plumbing systems. O-rings in this size range are commonly used to prevent leaks at valve stems, faucet cartridges, supply line connections, and other threaded or slip-fit plumbing joints. The kit format provides multiple rings in a single package, making it practical for service calls where having the right size on hand matters. Plumbers and experienced DIYers rely on rubber O-rings as a first step in diagnosing and repairing dripping faucets and leaking valves without full component replacement.

This kit is suited for general plumbing repair and maintenance work. Typical applications include faucet stem rebuilds, cartridge replacements, shutoff valve service, and fixture repairs in kitchens, bathrooms, and utility areas. The medium sizing targets mid-range fitting diameters most frequently encountered in standard residential plumbing configurations. Keeping a rubber O-ring assortment on the service vehicle reduces repeat trips and speeds up common repair jobs.

Installation Notes

Installation is typically performed by a licensed plumber or qualified DIYer familiar with basic plumbing repair. Always shut off the water supply and relieve line pressure before disassembling any faucet, valve, or fitting. Lubricate O-rings with a plumbing-safe grease prior to seating to reduce the risk of tearing during assembly. Work should conform to local plumbing codes and applicable IPC guidelines.
