Test 20 Type SKK Connection Thread M 16 x 2
Fast Coupling for:
• Monitoring and control of pressure
• Venting
• Sampling Fluids
Advantages:
• Coupling at system pressure level
• Connection is leakproof before piston valve is open
• Simple connection to measurement,
control and switching devices
• Self locking metal protective cap
• Minimizes introduction of contamination
to hydraulic systems
STA
Working Pressure:
• Max. working pressure 9000 PSI (630 bar)
For SKK type G, K and S the recommended working
pressure of fitting manufacturer should be noted
• Connection under pressure up to 5800 PSI (400 bar) max.
Materials:
• Metal parts: Steel, Stainless Steel on request
• Seals:
