Quick-connect coupling I.D. 7.2, nickel-plated brass, Hose 10x8 - Riegler 107293

Quick-connect coupling I.D. 7.2, nickel-plated brass, Hose connection 10x8, Operating pressure 0 - 35 bar, Temp. -20 °C to 100 °C Universal, one-hand quick disconnect couplings, one side sealing, suitable for a wide range of tasks and applications! The closed sleeve protects the coupling from dirt. To prevent injuries or a whiplash effect, we recommend that the plug-in nipple is held with one hand during uncoupling. These quick disconnect couplings are not suitable for direct attachment to pulsating tools. We recommend using our vibration dampers, according to ISO 6150 § 7.1. Areas of application: Pneumatic system, machine and plant engineering, measurement, monitoring and control systems, manufacturing industry, medical technology, chemical / pharmaceutical industry, workshops, automotive.

About Standard couplings

Quick-connect couplings separate and reconnect compressed air lines with one hand and without tools. The single shut-off design keeps the supply side closed while uncoupling, so the line does not empty. The range holds 232 items with an operating pressure starting at 0 bar and reaching 12 or 35 bar depending on the version.

What matters when choosing

• Connections run from M5 through G 1/8, G 1/4 and G 3/8 up to G 1/2, each as male or female thread. That choice is made by the mating part, not by the coupling.
• The body material governs corrosion behaviour and weight. Bright and nickel-plated brass for standard compressed air work, stainless steel 1.4305 and 1.4404 for aggressive surroundings, glass-fibre reinforced PA6 GF 30 for a non-metallic version.
• Seal material is available in NBR and FKM or FPM and, together with the body, defines the temperature window. Documented limits are -20 °C to 0 °C at the low end and 70 °C to 200 °C at the high end.
• Check the operating pressure against the application. The series are rated at a maximum of 12 to 35 bar.
• The version decides how the coupling handles in place. Rigid and 360° rotating variants are available, and individual items come without a through thread.

Typical applications

• Connecting air tools to preparation units and hose reels
• Assembly and repair benches with frequent tool changes
• Test rigs where lines are reconnected regularly
• Cleaning and wet areas using the stainless steel version
• Machine modules that are disconnected for changeover

The manufacturer recommends holding the plug nipple with one hand while uncoupling, to avoid injury from hose whip. Production takes place in Germany, Greece and China.
