Is the Twisted Quadrant Connector for Pneumatic Hoses, Type C11 compatible with soft plastic hoses up to 18 bar working pressure?

Yes. The Twisted Quadrant Connector for Pneumatic Hoses, Type C11 is specifically designed for hoses made of soft plastics and is suitable for use up to a working pressure of 18 bar. It provides a secure push-on connection secured with a screw-on nut, and its nickel-plated brass construction ensures durable, corrosion-resistant performance in demanding applications.

Can the Twisted Quadrant Connector for Pneumatic Hoses, Type C11 be used with fluids other than air (e.g., water, oil, chemicals) without compromising its nickel-plated brass construction?

The Twisted Quadrant Connector for Pneumatic Hoses, Type C11 is made of nickel-plated brass and is primarily described for pneumatic (air) systems with hoses of soft plastics and a working pressure up to 18 bar. Nickel-plated brass provides good general corrosion resistance and mechanical durability, so the fitting can tolerate exposure to water and many non-aggressive oils under similar pressure and temperature conditions. However, suitability for specific fluids (hydraulic oils, fuels, aggressive chemicals, solvents, acids, alkalis) depends on compatibility with both the brass plating and the hose material and seals (if any). Some chemicals can cause dezincification or attack the plating; certain oils or solvents may degrade soft-plastic hoses or their nut/fastening components. Pressure, temperature, and long-term exposure also affect performance. Conclusion: For water and many non-aggressive oils the Type C11 connector will likely perform adequately, but for aggressive chemicals, fuels, or demanding hydraulic fluids you must verify chemical compatibility of nickel-plated brass and the hose material (and any seals) with the specific fluid, and confirm pressure/temperature limits. When in doubt, consult the manufacturer or select fittings and hoses rated explicitly for the intended fluid.
