The JBO Thread Plug Gauge (NoGo) for BSP (G) Right-Hand threads is a compact, precision inspection tool built for plumbers, engineers, and maintenance teams. Sized for BSP (G) connections (6 x 11), it quickly verifies that threaded fittings conform to the No-Go limit, helping you confirm proper fit and reliable sealing before assembly.

• No-Go Limit for Quick Conformance Checks: Quickly confirms that a thread is within tolerance by preventing over-threading; if the gauge seats, it’s out of spec, signaling the need for a corrective part or rework. This reduces misfits and leak risks in plumbing, fluid handling, and equipment installations.
• Rugged Knurled Steel Body for Durable Use: The textured, knurled surface provides a secure grip in tight spaces and protects against dropped gauges, delivering long-lasting accuracy in workshop and field conditions.
• BSP (G) Right-Hand Compatibility: Specifically designed to test BSPG threads, ensuring accurate, repeatable checks for common plumbing and fluid-system fittings with reliable results.

This No-Go plug gauge helps you streamline your QC workflow, cut down inspection time, and reduce the risk of improper fittings that can cause leaks or downtime. By delivering clear, quick pass/fail feedback, it supports confident decision-making during installation, servicing, or QA checks—whether you're on a job site, in a workshop, or in a quality lab.
