Is the Quick Connector Plug for Injection Molds, GW Thread, No Valve – DYROS 90 Series suitable for coolant and compressed air up to 15 bar?

Yes. The Quick Connector Plug for Injection Molds, GW Thread, No Valve – DYROS 90 Series is suitable for coolant and compressed air up to 15 bar. It is brass-made, valve-free, and rated for a working pressure up to 15 bar, making it appropriate for cooling liquids in plastic processing and compressed air systems.

Can the Quick Connector Plug for Injection Molds, GW Thread, No Valve – DYROS 90 Series be used with aggressive cooling fluids or only with standard water-based coolants?

Quick Connector Plug for Injection Molds, GW Thread, No Valve – DYROS 90 Series is manufactured from high-quality brass and is described for use with cooling liquids, compressed air, gases and other technical installations up to 15 bar. Brass offers good general corrosion resistance and mechanical durability, so the coupling is suitable for standard water-based coolants and many common non‑aggressive fluids. However, the product description does not specify chemical compatibility with aggressive or corrosive cooling fluids (strong acids, alkalis, halogenated solvents, or highly chlorinated glycols). For aggressive media, brass can suffer dezincification or corrosion over time, compromising performance and safety. Therefore, do not assume compatibility—consult the coolant manufacturer’s chemical compatibility data and the coupling supplier for confirmed suitability, or choose materials specifically rated for aggressive fluids (e.g., stainless steel or specialty alloys) if needed.
