AirComParts Air Compressor Pressure Gauge, 1.5 in. and 2 in. Dial, 1/8 in. and 1/4 in. NPT
A tank gauge is a ten dollar part that tells you whether a three thousand dollar compressor is doing its job. When the needle sticks, reads twenty PSI low, or the lens fogs with oil, you stop trusting it. An untrusted gauge is the same as no gauge at all.
What is in this listing
Five dry (non liquid filled) gauges covering the two dial sizes that turn up on reciprocating compressors and shop air headers.
- 1.5 in. dial, 1/8 in. NPT, center back mount, 0 to 160 PSI (S2805)
- 1.5 in. dial, 1/8 in. NPT, lower mount, 0 to 160 PSI (S2830)
- 2 in. dial, 1/4 in. NPT, center back mount, 0 to 160 PSI (S2800)
- 2 in. dial, 1/4 in. NPT, center back mount, 0 to 300 PSI (S2820)
- 2 in. dial, 1/4 in. NPT, lower mount, 0 to 300 PSI (S2810)
Center back or lower mount
Center back mount puts the stem out of the rear of the case, which is what you want when the gauge drops into a panel cutout or threads into a manifold boss. Lower mount brings the stem out of the bottom at six o'clock, the usual arrangement on a tank nipple or a regulator body. The two are not interchangeable, so match whatever came off.
Picking the range
Size the range so normal running pressure sits near the middle of the dial. A single stage machine cutting out at 125 PSI reads well on the 0 to 160 gauge. A two stage at 175 PSI belongs on the 0 to 300. A gauge run pinned near full scale wears its movement and loses accuracy exactly where you need it.
