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.

Why this O-ring matters

In plumbing, a precise seal is everything. The #89 size is tailored to the common seating dimensions found in many American Standard faucet assemblies, delivering a durable, leak-resistant fit that stands up to regular use. Rubber construction provides a reliable compressive seal that remains effective across temperature swings and routine wear, reducing the risk of costly water damage and annoying drips.

Ideal use cases

  • Replacing worn or burned-in O-rings during faucet maintenance to restore a tight, leak-free seal
  • Sealing valve stems and supply-line connections where a 2-3/16 in outer diameter, 2 in inner diameter O-ring is required
  • Stocking a ready-to-go spare kit for households with frequent faucet upkeep or rental properties where quick service matters
  • Conversions or repairs on older fixtures that still rely on standard #89 O-ring sizing

Installation tips for best results

  • Before installing, shut off water and relieve any pressure. Remove the old O-ring and debris from the groove.
  • Clean the groove thoroughly to ensure a smooth seating surface for the new O-ring.
  • Lubricate the new O-ring lightly with silicone-based plumber’s grease for easier seating and a longer seal life—avoid petroleum-based lubricants.
  • Seat the O-ring evenly in the groove to prevent twisting or pinching during assembly.
  • Gently tighten connections to the recommended torque; overtightening can damage the O-ring and fixture.

Who benefits most

  • DIY homeowners undertaking faucet maintenance or minor repairs
  • Property managers and maintenance teams needing reliable, ready-to-use O-rings
  • Anyone replacing aging seals in American Standard faucets to ensure a durable, long-lasting seal

In short, this Danco O-ring kit is a practical, misplacement-resistant solution for keeping American Standard faucets running smoothly. With a precise #89 sizing, robust rubber construction, and a convenient 20-pack, it’s a dependable choice for timely repairs and ongoing faucet care.
