Thread Gauges for Whitworth Pipe Threads EN 10226 / ISO 7 | ULTRA Shop

Buy thread gauges for R, Rp & Rc threads (EN 10226 / ISO 7) 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 DIN EN 10226 and ISO 7 are utilized for the reliable inspection of joints where pressure-tight joints are made on the threads. Particularly in high-pressure systems, gas and water installations, and industrial apparatus and plant engineering, these inspection instruments ensure the absolute tightness and fit of pipe fittings. Due to the tapered thread geometry, the plug gauges and ring gauges feature only a single side. The go/no-go evaluation is performed precisely via the integrated tolerance step, which must align flush with the workpiece surface under axial screw-in force. Our portfolio seamlessly covers the common nominal size range from 1/16" to 6". You receive these wear-resistant measuring bodies manufactured from premium, hardened gauge steel. All gauges guarantee traceable calibration through optional factory or DAkkS certificates for your quality assurance.
