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.

About Product Overview

Secure, leak-free seals for reliable faucet performance — with the Danco 1 in. OD x 3/4 in. ID Rubber O-Ring (20-pack). This practical bundle is built for DIY repairs and professional use, delivering dependable sealing power across a variety of popular faucet brands.

Why this matters: a worn or damaged O-ring is the #1 culprit behind stubborn leaks and drip-prone faucets. With the right size and durable rubber formulation, these O-rings restore tight seals and help you avoid costly replacements or water waste.

  • Precision sizing: Exterior diameter 1", interior diameter 3/4", wall thickness 0.125" ensures a snug fit in standard faucet stems and valve assemblies.
  • Material you can trust: Rubber construction provides solid, flexible seals that resist compression over time and handle typical household water temperatures and pressures.
  • Broad compatibility: Designed to fit a wide range of brands, including Kohler, American Standard, Speakman, and Symmons faucets, making this a versatile addition to any repair kit.
  • Convenient bulk pack: Pack of 20 O-rings in a polybag—perfect for ongoing maintenance, multiple fixtures, or stocking your toolbox for future projects.
  • Round, proven design: Simple, classic O-ring geometry that slides into place and creates a reliable seal at the gasket groove.

Ideal use cases: replace worn seals during faucet rebuilds, fix minor leaks around stems and spouts, or keep a ready supply on hand for quick repairs in kitchens, bathrooms, and laundry areas. The 1" outer diameter and 3/4" inner diameter sizing makes it a practical choice for many common valve assemblies and stem seals.

How to install:

  1. Turn off the water supply and drain the faucet.
  2. Identify the correct O-ring size by measuring the groove or checking compatibility with Kohler, American Standard, Speakman, or Symmons fixtures.
  3. Gently remove the old ring and clean the groove.
  4. Lightly lubricate the new O-ring with a silicone-based plumber’s grease to ease installation and improve efficiency.
  5. Insert the O-ring into the groove, reseat the component, and restore water supply.

Pro tips for best results: - Always confirm outer and inner diameters before pairing with a fixture—a proper seal depends on correct sizing. - Store spare O-rings in a cool, dry place to preserve elasticity and prevent cracking.
