Compatible Models

We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.

Compatible equipment / model
  • Small electric air compressors using LF10-1H
  • Compressors requiring a single-port 1/4-inch NPT 95-125 PSI switch
  • Systems using a 1/4-inch compression unloader tube and matching motor amperage

Product Overview

A compressor that will not start, will not stop at pressure, or struggles against trapped head pressure may have a failed pressure switch after the motor, wiring, check valve, and unloader system are tested. The LF10-1H controls the motor and vents the pump discharge line at shutdown.

This listing is for the single 1/4-inch female NPT tank-port style. Verify electrical rating, port arrangement, lever, unloader tube, and pressure range before wiring.

Compatibility Notice

Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.

Match LF10-1H, single-port configuration, NPT thread, unloader tube size, motor voltage/amperage, and safe pressure range. Do not exceed the compressor tank or pump rating.

Frequently Asked Questions

Q: What does 95-125 PSI mean? A: The switch is listed to start the compressor near 95 PSI and stop it near 125 PSI.

Q: What does the unloader do? A: It vents trapped pressure from the pump discharge line so the motor can restart without a heavy load.

Q: Is this the four-port version? A: No. This listing is for the single 1/4-inch NPT tank-port LF10-1H configuration.

Q: Can I use it on any compressor? A: Only when the motor rating, pressure limits, port, unloader, and wiring match. Qualified electrical service may be required.
