The JBO Thread Ring Gauge (NoGo) for BSP (G) threads is a precision inspection tool designed to verify external thread diameters on fittings and pipework. Tailored for left-hand BSP (G) connections, it helps engineers, plumbers, and workshop teams quickly determine if a threaded component will thread correctly and seal reliably.

Featuring a no-go profile and a size specification of 2 3/4 x 11 with Tol. A tolerance, this gauge provides a clear pass/fail measurement during routine quality checks, assembly, or field service.

• NoGo profile for rapid conformance checks: The NoGo design lets you instantly identify undersized or oversized threads, speeding inspections and reducing downtime on job sites.
• Precise BSP (G) left-hand thread verification at 2 3/4 x 11: Uses the exact external thread geometry to confirm fit and sealing capability before assembly, helping prevent leaks and cross-threading.
• Durable, user-friendly ring gauge for daily use: Built for frequent handling in plumbing, fluid handling, and engineering environments, it maintains accuracy over time and integrates smoothly into existing inspection workflows.

This gauge supports faster, more reliable inspections, helping teams reduce rework and ensure every BSP (G) connection threads smoothly and seals properly. By clarifying pass/fail early in the workflow, it streamlines procurement, quality control, and field service, delivering consistent results across projects.
