JBO Thread Plug Gauge (GO) - BSP (G) - Left Hand - 1 1/2 x 11

The JBO Thread Plug Gauge (GO) is a precision tool for verifying BSP (G) threaded pipe connections. It’s designed for a wide audience—plumbers, engineers, technicians, buyers, and tradespeople—who need fast, reliable confirmation that fittings will seal correctly.

This GO gauge is sized 1 1/2 x 11 and configured for Left Hand BSP threads, enabling quick validation of left-handed fittings and preventing mismatches in critical piping systems.

• Go Gauge Design for Quick Conformance Checks: The GO orientation lets you rapidly confirm that threads meet BSP (G) standards, speeding up inspections and reducing rework by clearly indicating when a fit is correct.
• Precisely Machined BSP (G) Size 1 1/2 x 11: Meticulous dimensions deliver repeatable measurements across fittings, helping ensure reliable sealing and consistent test results.
• Left-Hand Thread Compatibility: Specifically built for left-handed BSP threads, expanding your testing coverage and preventing mismatches in specialty piping applications.

Using the JBO Thread Plug Gauge (GO) streamlines threaded-pipe inspections, reducing downtime by quickly identifying conforming threads and supporting quality control across plumbing, fluid handling, and engineering workflows. With its precise dimensions and targeted left-hand BSP compatibility, you can trust every test to indicate accurate fitment and sealing capability, helping you deliver reliable assemblies and faster project turnaround.
