Ashcroft pressure gauge with diaphragm seal

The Ashcroft 451259SD04L/50312HH04TXCF600# is a pressure gauge with diaphragm seal designed for pressure washer systems. It provides direct visual indication of operating pressure for operators and maintenance staff. The unit is supplied new and ready for integration into compatible equipment.

Threaded connection simplifies mounting

The gauge installs by threading the 1/2In process connection into the matching port on the pump or manifold. Use the correct sealant and torque to avoid leaks. Over-tightening can damage the diaphragm seal and affect calibration. Ensure the gauge face remains visible after installation for easy reading.

Verify port size and pressure range first

Confirm the equipment has a 1/2In threaded port that matches the gauge connection. Check that the system operating pressure falls within the gauge range marked on the dial. Review the diaphragm seal material compatibility with the fluid being measured before ordering.
