Competitive Comparison

Test couplings from the STAUFF Test 20 series with connection thread M16 x 2 and ball valve (type SMK) and poppet valve (type SKK) impress in a large-scale competitive comparison with a total of 11 comparable products from international manufacturers. These manufacturers represent an estimated 80 per cent of the global production volume for hydraulic test couplings.

Particular attention in the competitive comparison, which was carried out with real samples at the STAUFF Technology Centre in Werdohl-Ehrenfeld (Germany), was paid to the criteria:

• General design of the test couplings
• Pressure resistance
• Impulse resistance
• Dimensional accuracy and ISO 15171-2 conformity
• Surface coating

The overall assessment of the test results from the in-house test laboratory also included catalogue data.
