Swagelok PGI-115P-PG1000-LAPX-JQ Pressure Gauge

Swagelok PGI-115P-PG1000-LAPX-JQ is a 4.5-inch (115 mm) industrial process pressure gauge from the PGI series, engineered to measure system pressures from 0 to 1,000 psi with a secondary bar scale. It uses a 1/2 in. NPT male connection and is configured for lower-mount (LM) installation, ideal for compact panel or cabinet layouts. The gauge features a Bourdon-tube sensing element housed in a stainless-steel case (with PGI variants also offered in reinforced thermoplastic construction) and is available in unfilled or liquid-filled configurations to suit pulsation-prone lines. Swagelok PGI gauges deliver ASME B40.100‑level accuracy and are offered with a variety of end connections, including Swagelok tube adapters, plus mounting options such as center-back and lower-back to fit different panel builds. This LAPX-JQ variant is tailored to a lower-mount arrangement with standard Swagelok end connections, providing a rugged readout for process panels, industrial instrumentation, and equipment monitoring in manufacturing, chemical processing, and energy sectors where reliable 0–1,000 psi measurement is required.
