Pneumatic Threshold Sensor 1/4 NPT

The Legris 7808 04 14 is a pneumatic threshold sensor designed for compressed-air systems. It monitors pressure and triggers a signal when the set threshold is reached. The unit accepts a 1/4 in NPT female inlet and a 5/32 in tube connection. It suits maintenance engineers and automation technicians who need reliable pressure sensing.

Replaces worn or out-of-calibration sensors

Swap this unit in when an existing sensor drifts, leaks or fails to actuate at the correct pressure. The jump is worth it if the current device cannot hold the 43.5 psig minimum or 116 psi maximum operating range. A fresh sensor restores accurate switching without redesigning the pneumatic circuit.

Suits polymer-body NBR-sealed applications

This sensor fits systems that operate between 5 °F and 140 °F with a polymer body and NBR seals. It is not for buyers who need metal-bodied construction, higher temperature ratings or different seal materials. Installers requiring other thread types or tube sizes should look at alternative models.

Questions about this item

What thread size and tube diameter does the 7808 04 14 sensor need for mounting?

It requires a 1/4 in NPT female inlet and accepts a 5/32 in tube connection.

How is the sensor installed and which step is often missed?

Thread the 1/4 in NPT inlet into the port, push the 5/32 in tube fully into the connector, then verify supply pressure reaches at least 43.5 psig.

When will the NBR seals on this sensor need replacement?

Replace the NBR seals if leakage appears or after prolonged exposure near the 140 °F maximum operating temperature.
