The Asimeto Plug Thread Gauge (D/E) from the 690 Series is a precision tool built for professionals who work with British Standard Pipe fittings. Designed for right-hand BSP/BSPP threads, this 6H plug gauge provides accurate internal-thread verification to ensure reliable mating before assembly.

• Series and purpose: 690 Series plug gauge for BSP/BSPP internal threads, calibrated to 6H tolerance.
• Thread compatibility: Internal BSP and BSPP (G) threads, right-hand configuration for standard piping applications.
• Size: 1-1/8 in diameter x 11 TPI, matching the tested thread size and pitch.
• Dual-end design: Dual-threaded ends allow easy insertion and cross-checking of internal threads.
• Construction: Durable metallic body with a knurled grip and a red orientation band for secure handling and end identification.
• Durability: Built to withstand repeated use in demanding workshop environments while preserving measurement accuracy.

Using the gauge delivers precise, on-the-spot verification of BSP/BSPP internal threads, helping you confirm correct thread engagement before assembly. This reduces the risk of cross-threading and leaks, minimizes downtime, and supports consistent quality across pipe fittings, hydraulic lines, and pneumatic connections. The robust build and exact 6H tolerance ensure reliable performance across daily maintenance, fabrication, and field service tasks.
