  • Water filtration systems and irrigation setups

Frequently Asked Questions

Can I use this gauge for oil pressure measurement?

Yes, provided the media is compatible with brass internals. Avoid corrosive fluids.

What’s the difference between glycerin-filled and dry gauges?

Glycerin-filled models dampen vibration for steadier readings, while dry gauges are maintenance-free.

How do I calibrate a 1.5-inch pressure gauge?

Use a certified pressure source and adjust the calibration screw (if available) or seek professional service.

Top Picks for Reliable Performance

After testing multiple brands, we recommend GC Instrument’s stainless steel series for its balance of affordability and durability. Their spiral tube technology ensures long-term stability even in high-vibration environments.

Maximize Efficiency with Proper Maintenance

Regular inspection and calibration extend your gauge’s lifespan. Avoid over-pressure conditions and ensure threads are properly sealed during installation.
