The Asimeto Ring Gauge GO BSP/BSPP 6G from the 690 Series is a precision Go gauge designed for professionals who need reliable external thread verification on British Standard Pipe fittings. It ensures accurate checks for BSP and BSPP threads with industry-standard tolerance.

• Series & Tolerance: 690 Series Go gauge, built to the 6G tolerance class for consistent, repeatable measurements.
• Thread Compatibility: Designed to test external BSP and BSPP threads, ensuring proper engagement with standard fittings.
• Size & Orientation: Right-hand thread, Tol. A, 3/8 x 19 to match common BSP thread sizes used in fittings.
• Threaded Bore Design: Internal bore is threaded to the target profile, enabling precise go/no-go checks on the tested part.
• Material & Durability: Constructed with high-quality material to resist wear and maintain long-term accuracy.
• Ease of Use: Quick insertion and straightforward verification, ideal for routine QC checks in workshop or production environments.

Using this gauge, technicians can quickly confirm that a fitting’s external threads conform to BSP/BSPP standards, reducing guesswork and preventing mismatches during assembly. It supports reliable quality control, minimizes rework, and provides a clear pass/fail result for 3/8 x 19 fittings. This makes it a valuable tool for machinists, pipefitters, and service teams who require precise, durable thread verification in demanding settings.
