Pressure Gauge 4-1/2 Inch Diaphragm Seal

The Ashcroft 451259SD04L/50312SS04TXCG60#/VAC is a new electronic pressure gauge with a 4-1/2 inch nominal size and diaphragm seal. It is built for technicians and engineers who need reliable pressure measurement in test and measurement applications. The gauge suits industrial and automotive diagnostic work where a sealed sensing element is required.

Diaphragm Seal Isolation Limits

The diaphragm seal protects the gauge internals from corrosive, viscous or particulate media that would damage a direct-mount instrument. It also prevents process fluid from entering the gauge cavity, which matters for sanitary or hazardous installations. Users must verify that the seal materials and fill fluid are compatible with their specific process conditions and temperature range.

Model 451259SD04L/50312SS04TXCG60#/VAC Specification

Questions about this item

What does the 4-1/2 inch nominal size mean for readability?

The 4-1/2 inch dial provides a large, clear face that makes pressure readings easy to see from a distance or in low-light conditions, reducing the chance of misreading critical vacuum levels.

How does the diaphragm seal protect the gauge in vacuum service?

The diaphragm seal isolates the measuring element from the process media, preventing contamination and corrosion while ensuring accurate vacuum readings down to the 60 range indicated by the model code.

What connection standard does the 04TXCG60 fitting use?

The 04TXCG60 designation indicates a 1/4 inch connection with a specific thread and seal configuration designed to mate securely with compatible process ports for leak-free vacuum measurement.
