Storz couplings have an identical locking head with no separate male or female halves and are available with BSP male and female threads, or serrated hose tails for fitting into various types of hose. Blank caps are available for shutting off delivery when not in use. The maximum working pressure for this range of couplings is 16 Bar and they are stocked in aluminium alloy and brass with stainless steel units available upon request.
The Storz coupling locking head possesses 2 lugs. Any combination of female, male, hose tail or blanking cap can be secured together with the same lug dimension (this is sometimes referred to as The Ka distance and is expressed in millimetres). The common Ka distances are 31mm, 66mm, 89mm and 133mm although numerous other sizes are offered. We also offer storz reducers to convert from one Ka distance to another so any combination of sizes is possible making a quick & easy connection (eg 89mm x 66mm). Storz spanners are available which engage with the coupling housing to ensure a trouble free and leak proof seal is obtained. Storz fittings are suitable for water and a wide range of other fluids. Storz couplings are commonly used on tankers for powder blowing systems and fire fighting applications.
