Product Identity

This Legend Valve 800-665 is a 1/2" bottom-mount temperature and pressure gauge built for hydraulic system monitoring. It suits technicians and maintenance crews who need direct, local readings on fluid lines.

Installation Notes

The gauge threads into a 1/2" MPT port with a bottom-mounted stem for straight insertion. Misalignment during fitting can damage threads or cause leaks, so apply sealant carefully and avoid cross-threading.

Capacity and Limits

The unit displays both temperature and pressure on a single dial for combined system oversight. It is not intended for applications that require remote signalling, data logging or separate sensor outputs beyond the local indication.

Questions about this item

How do I confirm the 800-665 gauge is reading temperature and pressure correctly after installation?

Pressurise the hydraulic circuit to a known value and compare the needle to a calibrated reference gauge; the pointer should settle at the same mark without sticking or overshoot.

What comes with the 800-665 and what must I supply for a 1/2" MPT bottom-mount connection?

The box contains the gauge only; you must provide the 1/2" MPT pipe fitting, thread sealant and any required adapters for your hydraulic line.

Which Legend Valve model should I choose for a 1/2" bottom-mount temperature and pressure gauge?

The 800-665 is the sole model listed with a 1/2" MPT bottom mount for combined temperature and pressure indication.
