The JBO Thread Plug Gauge (NoGo) - BSP (G) - Right Hand - 5 x 11 is a precision inspection tool built to verify BSP (G) threaded pipe connections. It helps plumbers, engineers, and workshop technicians quickly confirm that threads meet spec, preventing leaks and misfits in fluid systems.

Designed for BSP (G) right-hand threads, this No-Go gauge features a dedicated No-Go end that makes non-conforming threads instantly identifiable. Its compact, hand-friendly design fits easily into tool kits and maintenance bays for fast checks on the shop floor.

• No-Go end for quick non-conforming detection: The No-Go end ensures threads that are out of spec cannot be threaded to full engagement, making rejected parts obvious and inspection faster.
• BSP (G) compatibility: Calibrated to standard BSP G dimensions to deliver consistent, reliable checks across pipe fittings, adapters, and connectors.
• Rugged, user-friendly construction: Knurled, corrosion-resistant body provides secure grip, accurate alignment, and durable performance in busy workshops—even with gloves on.

By using this gauge, you streamline quality control, reduce test time, and improve overall fit and seal performance in piping systems. It supports repeatable inspections, minimizes downtime, and gives your team confidence that every BSP (G) connection will seal correctly.
