Perma-Cal 4.5" Test Gauge | Direct Drive Pressure Instrument | Made in USA
Part Number: 101FTM18B21
Dial Size: 4.5"
Pressure Range: 0-15000 PSI
Accuracy: ±0.25% FS
Pointer Type: Test (knife-edge precision)
Case Type: Front Flange
Case Color: Blue
Connection: 1/4" NPT (Bottom (6 o'clock) position)

Perma-Cal pressure gauges use a helically-wound Inconel X-750 Bourdon tube as the only moving part—no gears, springs, linkages, or liquid fill to wear, break, or leak. Built to survive industrial environments, vibration, pulsation, and accidental drops.
One moving part—helically-wound Bourdon tube design
Inconel X-750 wetted parts with low coefficient of thermal expansion
316 SS standard connection material (Monel available)
300-series SS internal components
Internal pointer dampening—no liquid fill required
500% burst pressure / 150% proof pressure rating
Solid front case design for safety
NIST traceable calibration available on request
New, never used in service. Quantity 1 available at this price. Manufacturer MSRP: $399.10. Listed at distributor pricing—below MSRP.
Ships from Louisiana, USA. Same or next business day handling. Combined shipping available on multiple units. Questions about compatibility, calibration certificates, or specifications? Send a message—happy to help.
