Lordahl SG-1 Seat Gauge

Product Description

The LORDAHL SG-1 is a seat gauge used to measure and verify valve seat dimensions during service and repair work. Seat gauges give technicians a reliable reference for checking seat depth, width, or profile to ensure proper valve seating before reassembly. This type of tool is commonly used by licensed plumbers, HVAC technicians, and mechanical contractors working on valve bodies, faucets, or similar serviceable components where seat condition directly affects leak-free performance.

The SG-1 is suited for service environments where valve seat inspection or measurement is part of the standard repair workflow. It is a bench or field tool typically used alongside seat dressers or reamers during valve overhaul procedures in both residential and light commercial applications.

Follow applicable plumbing or mechanical codes for the jurisdiction where service is performed.
