Storz coupling sealed cap

The most common is the Storz Coupling Sealed Cap made of aluminum (cast or forged). Cast couplings have lower material strength and are more susceptible to casting flaws. They are only suitable for low working pressure (up to 6 bar) and less demanding applications. We supply high quality forged couplings with working pressures up to 16 bar as standard, but we also stock less expensive cast couplings.
