The JBO Thread Plug Gauge (NoGo) is a precision tool designed to verify BSP (G) threaded pipe connections. It’s ideal for plumbers, fluid-handling technicians, engineers, and workshop teams who need quick, reliable checks to ensure fittings meet BSP G standards and seal properly. Sized at 2 3/4 x 11 and featuring a textured knurled grip, this Left Hand gauge is built to perform in busy environments where accuracy matters.

• No-Go inspection design: The NoGo feature provides an immediate pass/fail indication, helping you quickly identify non-conforming threads and prevent mismatched fittings in assemblies.
• Left Hand BSP (G) compatibility: Specifically tuned for left-hand BSP (G) threads, ensuring correct fit verification and reducing guesswork during installation or maintenance.
• Durable, easy-grip construction: Knurled, textured handle offers a secure grip and easy handling in wet or oily conditions, supporting fast, repeatable checks in the field or shop.

Using this gauge helps streamline your workflow by delivering consistent, reliable thread verification, reducing rework, and improving confidence in every BSP (G) connection you install or inspect.
