Swagelok PGI-100C-PG200-LAP1 G.I. Gauge

The Swagelok PGI-100C-PG200-LAP1 G.I. Gauge is a 100 mm (4 in) dial industrial/process pressure gauge in Swagelok’s PGI series, engineered for precise pressure indication in demanding manufacturing and processing environments. It uses 316 stainless-steel wetted components and a case that can be glycerin-filled or left dry, with a socket restrictor for pulsation control and a crimped, tamper‑resistant seal between the case and lens. The gauge supports multiple mounting options and end connections, including center-back, lower-back, and lower-mount configurations and compatibility with Swagelok tube adapters for leak-tight installations. The PGI family is calibrated to ASME B40.100, EN837-1, and JIS B7505 standards and handles vacuum to high positive pressures up to 15,000 psi, making it suitable for both general industrial and process-monitoring applications. Dial sizes in the PGI lineup range from 40 mm to 160 mm, allowing this model to fit compact instrument panels as well as larger process enclosures, while offering filled or unfilled variants to suit system dynamics and visibility requirements. Common applications include process control, hydraulic and pneumatic systems, gas distribution, and other environments where reliable, easy-to-read pressure indication is essential.
