Why this bonnet packing matters
Bonnet packing is the crucial seal just under the faucet bonnet. When it wears or hardens, you may notice dripping, loss of compression, or a faucet that won’t shut off cleanly. This Danco bonnet packing provides a resilient rubber seal that compresses evenly to maintain a tight, leak-free connection, helping you extend the life of your faucet without a full replacement.
Ideal for DIYers and professionals
- Households with American Standard or Grand Haven fixtures that require bonnet packing with a 3/4" outer diameter and 3/8" bore.
- Maintenance pros looking for a ready-to-use, targeted replacement part that reduces downtime and simplifies repairs.
- Projects where restoring original valve performance without disassembly of larger components is preferred.
Easy installation and practical tips
- Shut off the water supply and relieve pressure at the faucet.
- Disassemble the faucet to access the bonnet area and remove the old packing.
- Clean the seating surface to ensure a crisp, even seal.
- Place the new bonnet packing onto the stem with the rubber facing the seating surface, ensuring a centered, straight fit.
- Reassemble, turn the water back on, and test for leaks. If a minor drip remains, re-torque lightly and recheck after a short pressurization period.
Maintenance tips for longevity
To maximize the life of this bonnet packing, avoid overtightening the bonnet and periodically inspect for wear or mineral buildup. In mineral-heavy water areas, a quick wipe-down after use helps maintain a clean seating surface and reliable seal over time.
Designed to fit American Standard and Grand Haven faucet models that use bonnet packing of these exact dimensions, this Danco part provides a targeted, reliable replacement option that keeps your faucet performing as it should. Ready for quick installation, bagged for secure packaging, and trusted for durability—it's a straightforward fix that delivers real, lasting results.
