RUKO HGB DIN 5157 HSS 55° Rp 2 inch Thread Plug Gauge

Verifying internal parallel pipe threads to DIN 5157 demands a gauge that holds its accuracy over thousands of checks. The RUKO HGB-DIN5157-HSS-55°-Rp-2 thread plug gauge provides a precise go/no-go test for Rp 2" internal threads, eliminating the uncertainty of visual inspection or makeshift measurement methods.

Who is it for

Quality control technicians, machinists, and maintenance engineers who work with BSPP (British Standard Pipe Parallel) threaded components in hydraulic, pneumatic, and general pipefitting applications. It suits both production floor inspection and incoming goods verification.

Tips

Clean the gauge and the workpiece before testing to avoid false readings. Apply a light oil film to the gauge threads to reduce friction and prevent galling. Store the gauge in its protective case when not in use to preserve accuracy.
