Storz couplings have an identical locking head with no separate male or female halves. The locking head is comprised of 2 lugs and comes equipped with serrated hose tails, female BSPP, male BSPP or blanking caps on the reverse side. They have a maximum working pressure of 16 Bar (232 psi) and are available in a range of materials including aluminium alloy, brass or stainless steel.
Storz couplings are secured together with an identical sized fitting with the same lug dimension (sometimes referred to as the Ka distance in millimetres). The most common size distances are 31mm, 66mm, 89mm and 133mm, but many other size variations are available. If there is a mismatch in coupling size between two fittings, we offer a range of reducers that provide a conversion from one Ka distance to another (e.g. 89mm x 66mm).
Our range of Storz couplings are commonly used to convey a wide range of fluids and are popular in firefighting applications or on tankers for powder blowing systems. We can also combine Storz coupling x hose tails with layflat fire hose to create assemblies if required.
