Oatey PP80080 Basin Coupling Nut Chrome 2 Pack

Product Description

The OATEY PP80080 is a chrome-plated basin coupling nut set used to secure supply line connections at faucet shanks and shutoff valve outlets beneath sinks and lavatories. Each nut features a chrome finish for a clean, corrosion-resistant appearance that holds up in exposed under-sink installations. The set includes two nuts sized at 1/2 inch and 3/8 inch, covering the two most common supply line termination points on a standard faucet or basin installation. Plumbers and pipefitters install these during faucet replacement, rough-in finishing, or supply line upgrades where original nuts are damaged or missing.

These coupling nuts are suited for residential and light commercial plumbing applications involving lavatory faucets, kitchen faucets, and similar basin fixtures. They are commonly used during faucet installation or replacement when connecting flexible supply lines to faucet inlet shanks or compression-style shutoff valves. The two-piece set addresses both the faucet-side and valve-side connections in a single package, reducing return trips to the supply house.

Key Features

• Chrome-plated finish resists corrosion and suits exposed under-sink installations
• Includes one 1/2 inch nut and one 3/8 inch nut for dual-connection coverage
• Two nuts per card for a complete supply line coupling solution
• Compact profile fits standard faucet shanks and shutoff valve outlets

Compatibility

Designed as a replacement coupling nut set for standard residential and light commercial basin faucet supply line connections requiring 1/2 inch and 3/8 inch nut sizes.

Installation Notes

Shut off the water supply at the angle stop or main before removing existing supply lines or coupling nuts. A basin wrench or adjustable pliers is typically used to access nuts in confined under-sink spaces. Hand-tighten first, then snug with a wrench - avoid over-torquing chrome-plated nuts to prevent cracking or stripping. Work must comply with applicable local plumbing codes referencing IPC standards.
