The JBO Thread Plug Gauge (GO) for BSP (G) left-hand threads is a precision go gauge designed to quickly verify BSP G threaded pipe fittings meet standard tolerances. Sized at 2 1/4 x 11, it helps ensure proper engagement and sealing in plumbing, fluid handling, and engineering applications.

Ideal for plumbers, engineers, inspectors, and field technicians, this gauge supports reliable quality checks in both manufacturing and on-site installations, helping you confirm correct thread conformity before assembly.

• Precise BSP G Go Verification: meticulously machined to the BSP (G) go dimensions so you can quickly confirm proper thread engagement and sealing without guesswork.
• Left-Hand Thread Design: specifically matched to left-hand BSP threads, reducing the risk of misreads in reverse-threaded applications and improving inspection accuracy.
• Durable, Ready-to-Use Construction: built for repeated use in workshops and field service, preserving tight tolerances for consistent, reliable results over time.

This go gauge helps streamline inspections, reduce workflow bottlenecks, and deliver confident pass/fail decisions, ensuring your BSP G fittings perform as intended in every application—from maintenance pits to high-demand fluid systems.
