Thread Gauges for Whitworth Pipe Threads DIN 2999 | ULTRA Shop

Buy thread gauges for Rp internal & R external threads (DIN 2999) from 1/16" to 6" online. ULTRA taper gauges with tolerance step for pressure-tight joints.

Thread gauges for tapered Whitworth pipe threads according to the classic DIN 2999 standard are used for the process-secure inspection of pressure-tight pipeline connections in traditional piping, heating, and plumbing installations. Due to the tapered thread system, the plug gauges for checking the cylindrical Rp internal thread and the ring gauges for checking the tapered R external thread naturally feature only a single side. The evaluation is performed via the integrated tolerance step, which must align completely flush with the workpiece surface under standard screw-in force. You receive these wear-resistant measuring bodies from the premium ULTRA brand, manufactured from high-grade, hardened gauge steel. All gauges guarantee traceable calibration through optional factory or DAkkS certificates for your quality assurance.
