This series separates digital inflator gauges from handheld digital pressure-checking tools. Each configuration combines an electronic pressure reading with an air-supply connection, but display units, batteries, hoses and working limits vary. The GC02 includes an LED work light and rechargeable battery; other models use AAA batteries or a CR2450 cell. Choose by the actual pressure parameter shown in the table and confirm the air connection for the workshop system. STG-14, STG-15 and STG-18 list 0–100 PSI measuring ranges. STG-21 extends the stated measuring range to 255 PSI. STG-22 adds vacuum, inflation, deflation and pressure-measurement functions, with its range to be confirmed because the catalogue entries differ. STG-25 has a dual-foot chuck and 13.4 in (340.4 mm) hose; STG-26 has a T-type clip-on chuck and 20 in (508 mm) swivel hose.
Model Differences
- GC02 lists a 0–150 PSI LED display, a work light, a G 1/4 inlet and a 13 in (330 mm) PVC hose.
- The 230 PSI model lists a 3–230 PSI measurement range and 0.1 PSI resolution; the heavy-duty model lists a 5–250 PSI inflation range.
- The two 145 PSI configurations have the same stated maximum working pressure but different handle design and weight.
- STG-13 has conflicting range entries in the catalogue; its supplied scale requires confirmation.
- STG-14, STG-15 and STG-18: 0–100 PSI LCD configurations. STG-14 and STG-15 separately list a 150 PSI maximum pressure.
- STG-21: 0.35–255 PSI detailed range with two LR03 batteries. STG-22 adds vacuum and deflation functions; confirm the supplied pressure range.
- STG-25: 0–200 PSI, dual-foot chuck and 13.4 in / 340.4 mm hose. STG-26: 0–174 PSI, T-type clip-on chuck and 20 in / 508 mm swivel hose; confirm the inlet.
Applications
Workshop tire inflation
Compare digital displays and pressure limits for use with a compatible external compressed-air source.
Low-light valve access
Consider the GC02 work-light configuration where additional illumination at the valve is useful.
Distributor assortments
Specify inlet, hose, display units, battery preference and quantities for the selected models.

* Confirm STG-13 and STG-22 pressure ranges and the STG-26 inlet because catalogue entries conflict; see the notes beside each model. Configurations without published SKU codes use their existing descriptive names. Hose dimensions include inch/mm equivalents; nominal G/NPT sizes are thread designations.

Frequently Asked Questions
Does the battery inflate the tire?
The battery powers the electronic display and, where fitted, the light. These inflator gauges require an external compressed-air supply to add air.
Which model has an LED work light?
GC02 is the listed LED work-light configuration, with a 0–150 PSI display, rechargeable battery and 13 in (330 mm) PVC hose.
Can the digital inflators use the same air connector?
Connections vary. GC02 lists G 1/4, while other models list NPT threads or quick-connect plugs. Confirm thread standard and plug profile for the selected model.
Which catalogue specifications need confirmation?
STG-13 is listed at 0–255 PSI in the table but 0–100 PSI in its description. STG-22 is listed at 0–255 PSI in the table, while the detailed page gives positive pressure of 0.35–250 PSI and a vacuum range. STG-26 is listed with a 1/4 in plug in the table and 1/4 in FNPT in the detail. Confirm these entries for the supplied configuration.
Can I request different models in one quotation?
Yes. Select the required models, enter the quantity for each and use Request Quote for Selected Models. Include your delivery country and any branding or packaging requirements.
