Ashcroft 451279SS04LXLL200 Pressure Gauge
The Ashcroft 451279SS04LXLL200 is a process pressure gauge with a 4 1/2 inch dial and a primary range of 0 to 200 psi. It suits technicians and plant operators who need accurate local pressure indication on compatible process lines. The phenolic case and glass lens are built for industrial environments where durability matters. Its bottom-mounted male NPT connection fits standard 1/2 inch female ports.
PLUS! Performance Dampening Feature
The dry PLUS! Performance dampening feature resists vibration without liquid fill, so the needle stays readable on pulsating lines. Because the case is not field fillable, there is no option to add glycerine or silicone later. The white dial with black markings supports the stated accuracy of +/- 0.5 percent across the full scale. Vibration resistance is achieved through the dry case design alone.
Check Connection Size and Mounting Orientation
Verify that your process piping has a 1/2 inch female NPT port at the intended instrument location. The gauge mounts with the connection at the bottom, so ensure there is clearance for the 4 1/2 inch dial face. Confirm the media is compatible with the wetted materials implied by the standard construction. The phenolic case is black and the unit measures 6.500 by 6.300 in overall footprint.

Questions about this item
Will the phenolic case or glass lens of the Ashcroft 451279 gauge need replacement after extended service?
The phenolic case and glass lens are built for durability; no scheduled replacement interval is defined by the manufacturer.
What pressure limit stops the gauge from reading higher during sustained use?
The primary range tops out at 200 psi, so sustained pressure above that value exceeds the calibrated span.
Does the dry PLUS! Performance dampening add noticeable heat or vibration noise when the gauge runs continuously?
The dry vibration-dampened case produces no fan noise or measurable heat rise during all-day operation.
