The JBO Thread Ring Gauge (GO) is a precision gauge designed to verify external BSP (G) threads. With a size specification of 2 3/4 x 11 and Tol. A, it’s an ideal tool for plumbers, engineers, buyers, technicians, and workshop staff who need reliable, quick confirmation that fittings meet BSP G standards.

• BSP (G) GO accuracy: Quickly determine if external threads conform to BSP (G) standards, enabling fast pass/fail checks and reducing guesswork during assembly or quality audits.
• Left-hand orientation: Configured specifically for left-hand thread applications, ensuring correct gauge fit and efficient inspection in projects with left-handed BSP fittings.
• Precise tolerance and durable construction: Maintains consistent measurements across multiple uses, delivering dependable results in busy workshops and field environments.

Using this gauge helps you accelerate inspections, improve reliability of connections, and maintain high-quality outcomes across plumbing, fluid handling, and engineering applications. Its clear GO indication supports confident decision-making, minimizes downtime, and promotes consistent performance throughout your workflow.
