The JBO Thread Ring Gauge (GO) is a precision inspection tool designed to verify external BSP (G) threads. Sized for right-hand, 1/4 x 19 BSP G fittings, it helps plumbers, engineers, and quality teams quickly determine if a thread is within tolerance and ready for assembly. Its Go design provides an immediate, clear indication of conforming threads, helping you speed up inspections and reduce guesswork in your workflow.

• Go Gauge Design for Fast Conformity Checks: Enables quick pass/fail verification of BSP G external threads, shortening inspection time and minimizing rework by clearly showing which fittings meet specifications.
• Size-Specific BSP G 1/4 x 19 Verification: Precisely tuned to the 1/4 x 19 right-hand BSP (G) standard, delivering reliable diameter checks and improving fitting compatibility in plumbing and fluid handling.
• Rugged, Precision-Machined Construction: Made for durability with a knurled outer edge for a secure grip, providing long-lasting performance in busy workshops and resisting wear in daily use.

This gauge helps streamline quality control and maintenance tasks by delivering clear, actionable results. By confirming proper thread engagement and sealing capability, it supports faster assembly decisions, reduces downtime, and enhances overall accuracy across plumbing, hydraulic systems, and engineering applications.
