The JBO Thread Ring Gauge (NoGo) is a precision inspection tool crafted for BSP (G) right‑hand threads. Sized for external thread diameters, it supports quick, reliable verification at the 2 1/2 x 11 dimension with Tol. A, helping plumbers, fluid-handling technicians, engineers, and maintenance teams confirm correct thread fit and sealing capability.

Designed with a clear NoGo limit, this gauge makes non‑conforming BSP (G) threads easy to identify—reducing guesswork and rework in both fieldwork and workshop settings. The tool’s robust construction and knurled outer edge provide confident handling in busy environments, even with gloves on.

• Go/No-Go verification for BSP (G): Enables rapid pass/fail checks on external threads, speeding inspections and improving consistency across jobs.
• Precisely sized for Tol. A 2 1/2 x 11 BSP (G) right‑hand threads: Ensures reliable, repeatable measurements aligned with standard workmanship practices.
• Rugged, easy-to-handle construction: Metal body with a knurled edge delivers durability and secure grip in demanding shop or field conditions.

Using this gauge helps you streamline threaded fitting inspections, minimize downtime, and verify that BSP (G) components will seal correctly when installed. It supports accurate quality checks across plumbing, fluid handling, and engineering applications, giving teams confidence in every connection.
