The JBO Thread Plug Gauge (NoGo) for BSP (G) left-hand threads is a precision inspection tool designed for plumbers, engineers, and quality inspectors. This compact gauge helps ensure threaded pipe connections meet BSP (G) standards and will seal reliably, making it a trusted addition to any workshop or field kit. Model: 2 x 11.

• Fast No-Go Verification: Quickly identify out-of-tolerance threads with a single check, reducing inspection time and preventing incorrect fittings from progressing into production or fieldwork.
• Left-Hand BSP (G) Compatibility: Precisely matched to BSP (G) left-hand thread profiles, ensuring accurate assessments for common piping systems and preventing mismatches in assemblies.
• Rugged, Easy-To-Handle Design: Textured knurling and a compact grip provide secure handling in tight spaces, while the overall build supports repeated use in busy workshop or field environments.

This plug gauge helps you streamline inspections, saving time and reducing costly rework. By validating BSP (G) left-hand threads at the critical no-go limit, it provides clear pass/fail results for every connection. Built for durability and comfortable handling, it supports consistent, leak-free fittings across plumbing, fluid handling, and engineering applications.
