Boshart PG25-WTG300 2.5" Water Test Gauge, 0-300 PSI

Boshart PG25-WTG300 2.5" Water Test Gauge, 0-300 PSI

The Boshart PG25-WTG300 is a 2.5" water test gauge with a 0-300 PSI range, built for plumbers and contractors who need a fast, reliable way to pressure-test rough-in systems before they're closed up behind a wall or under a slab. This gauge attaches directly to hose bibbs, boiler drains, and lawn faucets, giving you an immediate visual read on system pressure so you can catch leaks before final inspection. It is commonly paired with rubber test caps to fill and pressurize sewer, drain, and waste water lines during rough-in testing, making it a go-to tool for verifying DWV and water line integrity on new construction and renovation jobs. The connection swivels, which means you can thread the gauge onto a fitting and rotate the dial face to a readable position without twisting or loosening the connection itself — a small detail that saves real time when you're working in a crawlspace or tight mechanical room. Sold in cartons of 50, the PG25-WTG300 is a practical stock item for shops and service trucks that run pressure tests on a regular basis.
