The JBO Thread Plug Gauge (NoGo) for BSP (G) right-hand threads is a precision inspection tool designed for plumbers, engineers, and workshop technicians. With a size of 1 3/4 x 11, it helps you quickly verify that BSP threaded fittings will seal properly by exposing non-conforming threads before assembly.

Designed around a NoGo profile and calibrated to BSP (G) standards, this gauge delivers reliable go/no-go results that reduce guesswork and rework in quality control and field installations.

• Precise BSP (G) NoGo dimensions: Calibrated to BSP (G) right-hand threads, this gauge provides clear pass/fail readings at 1 3/4 x 11 to ensure only compliant threads are used, helping prevent leaks and mismatches.
• Durable, knurled construction: Rugged metal body with a textured, knurled surface offers a secure grip and long life in busy workshops and on-site environments, even when wearing gloves.
• Fast go/no-go verification: The NoGo design allows instant confirmation of thread conformity, speeding up inspections and reducing downtime during assembly and maintenance.

Using the JBO NoGo BSP gauge translates to faster, more reliable inspections, fewer rework events, and smoother installation workflows. Its durable construction and precise dimensions help ensure consistent results across operators and environments, giving you confidence in every threaded connection.
