The JBO Thread Plug Gauge is a precision tool for verifying BSP (G) left-hand pipe threads. Sized at 7/8 x 14, it provides fast, reliable checks for fittings, adapters, and connectors used in plumbing, fluid handling, and engineering applications.

With its go/no-go design and two-ended construction, this gauge lets technicians quickly identify conforming and non-conforming threads, reducing trial-and-fit time and helping ensure proper seal and fit.

• Go/No-Go Verification for Quick Conformance: Effortless pass/fail checks let you confirm tolerance compliance at a glance, speeding inspections in workshops and field service.
• Left-Hand BSP (G) Compatibility: Specifically tuned for left-hand BSP (G) threads, ensuring accurate engagement and reliable measurements for these specialized fittings.
• Durable, Ergonomic Construction: Knurled grip and color-coded end markers provide a secure handling experience and easy orientation in busy environments, with long-lasting performance.

Using the JBO Thread Plug Gauge helps streamline quality checks, reduces downtime from ill-fitting fittings, and supports consistent, reliable results across plumbing and industrial fluid systems. Its rugged construction is built to withstand daily use in both field and workshop settings, giving you confidence with every measurement.
