Brass Self-Closing Faucet 08540

The Zoro Select 08540 is a brass faucet designed for plumbing systems requiring a 1/2-20 UNF thread. Its self-closing mechanism stops flow automatically when the handle is released, suiting industrial wash stations or mobile equipment where hands-free shut-off is preferred.

Thermals Noise and Power Draw

This mechanical valve has no electrical components, so it produces no heat, draws no power and operates silently. Performance depends entirely on the supply pressure and temperature of the fluid being controlled.

Build Quality and Connections

The all-brass body resists corrosion in water and mild chemical service, while the 1/2-20 UNF male thread allows direct installation into matching ports without adapters. Self-closing action reduces waste and prevents accidental flooding if the valve is left unattended.

Questions about this item

How do I install the 1/2-20 UNF thread on this brass faucet, and what step is often missed?

Thread the 1/2-20 UNF connection into the matching port by hand first, then tighten with a wrench; the step often missed is starting it straight to avoid cross-threading the brass.

What maintenance will the self-closing mechanism need over time?

The internal spring and seal in the self-closing cartridge should be inspected periodically and replaced if the faucet drips or fails to shut off cleanly.

What limit appears first when the faucet runs continuously?

The brass body handles sustained flow, but the self-closing spring can fatigue first, causing slower shut-off or incomplete closure after extended use.
