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.
