Air Compressor Pressure Switch 105-135 PSI Single Port Metal Housing 1/4"

Heavy-Duty Metal Housing 105-135 PSI Pressure Switch for Single-Stage Air Compressors

This is a brand-new heavy-duty pressure switch designed for single-stage air compressors operating within a 105-135 PSI range. Built to handle electric motors rated up to 24 amps, this switch features a durable metal housing ideal for industrial environments.

The unit includes a side-mounted unloader valve but does not come with an integrated on/off lever. To manually operate, a separate on/off switch must be installed upstream, or the circuit breaker can be used for power control.

This metal-style pressure switch is commonly found on older industrial compressors and industrial climate control systems. It’s also a great universal replacement option for users seeking a robust upgrade—just ensure the connection types and pressure settings match your application.

Its larger housing provides more internal space for wiring compared to standard plastic pressure switches.

Specifications:

• Preset ON/OFF Pressure: 105-135 PSI

• Tank Connection: ¼" Female NPT (Note: 1/4" NPT measures approximately 1/2" in diameter)

• Unloader Valve: ¼" Compression Fitting (Note: This accepts nylon, aluminum, or copper tubing with a 1/4" outside diameter)

• Overall Dimensions: 4" Height x 3.5" Width x 3.75" Depth

• Electrical Rating: Supports up to 24 Amp Electric Motors

This switch is an excellent solution for demanding shop or industrial applications where reliability and durability matter.
