Collection: Major Components - Gauges

Cast Air pressure gauges cover both tank-side and line-side monitoring needs for compressor installations. These are OEM-spec replacements from Cast Air, a family-owned manufacturer out of Spicer, MN building all-cast-iron compressor components since 1991. Thread sizes and pressure ranges match original equipment specifications, so you're not adapting or guessing at fitment.

Whether you need a back-mount tank gauge rated to 300 PSI or a lower-range line gauge for regulated output, the correct specification is what matters — not a close substitute. As authorized Cast Air dealers, we stock gauges sized for their piston compressor lineup and can confirm compatibility before you order.

If you're not certain which gauge your unit requires, call us at 866-217-0063 and we'll match you to the right thread size, pressure range, and mount configuration.
