Value Brand
Measures 0-300 psi with a 2 1/2 in dial and 1/4 NPT bottom connection in a 304 stainless steel case
This Value Brand commercial pressure gauge measures from 0 to 300 psi with a 2 1/2 in dial. It features a 304 stainless steel case, acrylic lens and a 1/4 in male NPT bottom connection. The white dial offers +/-3-2-3 percent accuracy and the unit is liquid-filled for vibration resistance.
This gauge suits technicians who need a bottom-mounted, liquid-filled instrument for steady readings in vibrating environments. It is not for buyers who want a field-fillable case or a gauge with an IP or NEMA rating for sealed protection. It also does not suit applications that require a connection size other than 1/4 in NPT.
The liquid-filled design comfortably handles pressure cycles up to 300 psi while damping pointer flutter from pump or line vibration. The 304 stainless steel case resists corrosion in typical commercial settings. It runs out of headroom for processes exceeding 300 psi or for installations that demand a rated environmental seal.

The gauge has a 1/4 in male NPT process connection at the bottom, so the mating port must be female 1/4 NPT.
Yes, the gauge case is also 304 stainless steel, so it is metallurgically compatible with your current piping.
Apply a known reference pressure within the 0 to 300 psi range and confirm the pointer stays within the stated +/-3-2-3 percent accuracy band.
