Mountain Plumbing MT957/ULB Air Switch Unlacquered Brass

Product Description

The MOUNTAIN PLUMBING MT957/ULB is an air switch finished in unlacquered brass, designed for pneumatic activation of garbage disposals or other sink-mounted appliances without the need for a direct electrical connection at the countertop. When the button is pressed, a burst of air travels through a tube to a remote power module that completes the electrical circuit. Licensed plumbers and kitchen installers typically handle the countertop and under-sink components of this type of installation. The unlacquered brass finish delivers a raw, natural metal look that develops a patina over time, making it a common choice for period-appropriate or custom kitchen designs.

This air switch is suited for residential kitchen installations where a countertop-mounted activation point is preferred over a wall switch. It is typically deck-mounted through a standard sink or countertop knockout and connects to a separate pneumatic power unit located in the cabinet below. The unlacquered brass finish is appropriate for installations where the fixture finish will age naturally alongside other unlacquered brass hardware.

Key Features

• Pneumatic activation eliminates direct electrical contact at the countertop switch point
• Unlacquered brass finish ages naturally to develop a patina over time
• Deck-mount design fits standard sink or countertop knockouts
• Compatible with remote pneumatic power units for garbage disposal or similar appliance control

Compatibility

Designed as an OEM-style countertop air switch for use with pneumatic power units in residential sink and disposal installations.

Installation Notes

Installation is typically performed by a licensed plumber or experienced installer. Shut off power to the disposal or connected appliance at the breaker before working on the under-sink power module. The pneumatic tubing connecting the countertop button to the power unit should be routed without sharp kinks that could restrict airflow. Follow all applicable local plumbing and electrical codes during installation.
