The JBO Thread Ring Gauge (GO) for BSP (G) right-hand threads is a precision tool designed to verify external BSP (G) threads quickly and reliably. Sized for 3/8 x 19 with Tol. A tolerance, it provides fast go/no-go verification that a threaded connection will fit and seal as intended.

Designed for a wide range of users—from plumbers and pipefitters to engineers and quality inspectors—it streamlines inspection of threaded fittings, helping you avoid misfits and rework. Use it in construction, maintenance, or manufacturing environments to ensure every BSP (G) connection meets the expected standard before assembly.

• Accurate BSP (G) go gauge for 3/8 x 19: Precisely checks external thread diameter against BSP (G) standards, enabling fast confirmation of proper fit and sealing before assembly.
• Durable, knurled ring design: Rugged metal body with a knurled edge provides a secure grip and long service life in busy workshop environments, reducing downtime.
• Right-hand orientation with Tol. A tolerance: Specifically designed for standard right-hand threads with tight Tol. A tolerance to deliver consistent, repeatable measurements across multiple checks.

With the JBO Thread Ring Gauge (GO), you gain confidence in every threaded connection. It speeds up quality checks, minimizes guesswork, and helps ensure fittings will thread smoothly and seal reliably in plumbing and fluid-handling systems. The durable construction stands up to daily use, making it a dependable addition to tool kits for workshop, field service, or manufacturing environments.
