The Castair G201420U is a 1/4-inch NPT bottom-mount pressure gauge with a 2-inch dial face, reading 0 to 200 PSI. Priced at $11.86, this is the bottom-mount version of the G201420B — same connection, range, and dial size, with the port exiting from the base of the gauge housing for upright installation off horizontal fittings.
The 2-inch dial and 1/4-inch NPT connection make this gauge suitable for compressor tank ports and manifold installations where readability matters. Bottom-mount gauges are the natural choice for most compressor tank gauge ports, where the port is drilled horizontally in the tank shell and the gauge is expected to stand upright with the dial reading toward the operator.
