Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

This size-specific O-ring addresses common wear points in faucet cartridges and valve seals, offering a readily available replacement that reduces the risk of leaks after maintenance or cartridge replacement. The #29 designation helps you quickly identify the right fit for many Delta and Symmons components, so you don’t have to guess when shopping for repair parts.

Ideal use scenarios:

  • Replacing worn or damaged O-rings in Delta and Symmons faucet cartridges
  • Valving and seal repairs where a 1-1/8 in ID, 1-1/4 in OD rubber ring is specified
  • Routine maintenance kits for bathroom and kitchen fixtures to prevent ongoing leaks

Why choose this Danco O-ring kit:

  • Durable rubber construction designed to resist common household water minerals and standard household temperatures
  • Specific size match (ID 1-1/8 in, OD 1-1/4 in, 1/16 in thick) ensures a reliable seal without over-compression
  • 20-pack value means you have spares on hand for multiple repair projects or future replacements
  • Compatibility with popular Delta and Symmons fixtures makes it a practical addition to any homeowner’s repair kit

Practical installation tips:

  • Shut off the water supply and drain the lines before starting. Remove the old O-ring and clean the groove thoroughly.
  • Lightly lubricate the new O-ring with a silicone-based lubricant to ease installation and improve seal longevity. Avoid petroleum-based lubricants, which can degrade rubber over time.
  • Gently seat the O-ring in its groove without twisting. Ensure there are no debris or nicks in the groove that could compromise the seal.
  • After reassembly, test for leaks at the faucet or valve to confirm a proper seal before normal use.

Tip for longevity: store spare O-rings in a cool, dry place away from direct sunlight to prevent drying or hardening. Replace O-rings in pairs when servicing a valve or cartridge to maintain symmetrical sealing and optimal performance.
