The VÖLKEL Precision Dưỡng kiểm ren trong G (BSP) 1" × 11 is your reliable and precise instrument for inspecting British Standard Pipe Parallel threads. Whether you’re in quality assurance, production, or maintenance, this GO/NO-GO gauge provides a fast and clear assessment of thread accuracy in accordance with DIN ISO 228.
The plug gauge combines two essential functions in one tool: The GO end must screw smoothly into the ren trong by hand, proving that the minimum dimension is within tolerance. The NO-GO endmarked with a red ringmust not enter more than two turns – ensuring the upper limit of tolerance isn’t exceeded. This simple test guarantees reliable results without requiring advanced metrology equipment.
BSP threads (British Standard Pipe) are commonly used in fluid and pneumatic systems. They differ from metric threads by their 55° Whitworth angle and inch-based sizes. While metric threads often seal along the flanks, BSPP threads (G type) seal at the face, typically using washers or O-rings. Ensuring the thread dimensions are correct is crucial for leak-free connections – and that’s where this precision gauge delivers consistent accuracy.
Each gauge is manufactured to the highest standards of dimensional stability. On request, VÖLKEL provides a factory calibration certificateconfirming compliance with the required international standards and traceability through independent measurement using IAC thread scanners.

What is the difference between BSP and metric threads?
BSP threads are inch-based and have a 55° flank angle, while metric threads are measured in millimetres with a 60° angle. BSP threads are used in pipe and hydraulic systems; metric threads are used in general mechanical applications.
Can I use this gauge for BSPT (tapered) threads?
No, this gauge is designed for parallel BSPP (G-type) threads only. Tapered BSPT threads require a different plug gauge type.
How often should I recalibrate the gauge?
Depending on frequency of use, recalibration every 12–24 months is recommended for reliable accuracy.
What happens if the NO-GO end goes in more than two turns?
The thread is oversized and out of tolerance. This usually indicates tool wear or incorrect drilling dimensions.
Can I request a calibration certificate?
Yes. VÖLKEL offers a factory calibration certificate on request. Calibration is performed independently according to DIN, ISO and ANSI standards.
