Test Couplings with Plug-In System - SMK10
Test Couplings with ball check for normal hydraulic applications and hydraulic applications with high-viscosity fluids.
Area of Application
▪ Monitoring and control of pressure
▪ Venting
▪ Sampling in high- and low-pressure systems
Advantages
▪ Coupling at system pressure level
▪ Leakproof connection before ball check is open
▪ Simple connection to measuring, control
and switching devices
Media
▪ Suitable for hydraulic oils and other mineral oil based fluids
(Check compatibility of sealing material)
▪ For use in conjunction with other liquid media please
consult STAUFF
Working Pressure
▪ Max. working pressure 400 bar / 5801 PSI
For SMK style G and K the recommended working
pressure of fitting manufacturer has to be applied.
Materials
Metal parts made of:
▪ Steel, zinc/nickel-plated = C6F (CrVI-free)
Ball made of Stainless Steel
Sealings made of:
▪ P = NBR (Buna-N®)
Temperature range -20 °C ... +100 °C / -4 °F ... +212 °F
▪ V = FPM (Viton®)
Temperature range -20 °C ... +200 °C / -4 °F ... +392 °F
▪ E = EPDM (Ethylene Propylene Diene Rubber)
for brake fluid,
Temperature range -40 °C ... +150 °C / -40 °F ... +302 °F
