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

Prevent drips and leaks with the Danco Rubber O-Ring 20-pack, a focused, ready-to-use seal solution designed for real-world plumbing fixes. This set centers on a precise, durable rubber O-ring that fits a variety of popular fixtures, making it an essential stocking staple for DIY homeowners, pros, and property managers alike.

  • Interior diameter 1-3/16 in, exterior diameter 1 in, wall thickness 3/32 in. Each ring is perfectly round for a consistent, even seal.
  • Rubber provides reliable compression and resistance to typical household fluids, helping to seal faucets, valves, and small fittings where a tight, long-lasting seal is needed.
  • 20 O-rings per polybag package—great for stock, multiple fixtures, or ongoing maintenance without frequent repurchases.
  • Designed to fit a range of common fixtures and brands, including American Standard, Alamark, Eljer, Jameco, Speakman, and Aqual Seal, so you’re not stuck hunting for a single-specific seal.
  • Round, uniform O-rings that install quickly and evenly, reducing the risk of mis-seating and leaks.

Why this matters for you

Leaks often start with a worn or mis-seated O-ring. The Danco 20-pack offers a precise, dependable rubber seal that restores watertight performance for everyday fixtures—faucets, valves, and other connection points that rely on a tight, durable seal. With a compact 1-inch exterior diameter and a generous interior diameter, these rings are well-suited for standard valve seats and cartridge assemblies found in many homes.

Who should consider this set

  • DIY homeowners tackling slow drips or small leaks in kitchen and bathroom fixtures
  • Maintenance teams stocking a versatile, ready-to-use seal kit
  • Renters or property managers who want a practical, economical spare parts option

Practical tips and use cases

  1. Shut off the water supply and drain the line before beginning any O-ring replacement.
  2. Remove the old O-ring carefully. Clean the groove with a soft cloth to remove debris and mineral buildup.
  3. Lightly lubricate the new O-ring with a silicone-based plumber’s grease or compatible lubricant to aid installation and extend life.
  4. Gently seat the new O-ring in the groove, ensuring it lies evenly without twists or pinches.
  5. Reassemble the fixture and slowly turn the water back on. Check for leaks and reseat if necessary.

Enhance reliability, reduce recurring leaks, and keep essential fixtures performing at their best with this versatile Danco O-ring set. The polybag packaging makes it easy to store and access whenever maintenance is due, and the compatibility with multiple popular brands means it’s a smart, universal addition to any toolbox or maintenance closet.
