The manufacturing methods and working parameters are different. The cast couplings can only be used for low working pressure (max. up to 6 bar) and for less critical applications due to the brittleness of the components. The forged couplings are designed for more critical applications and can operate at a maximum working pressure of 16 [...]
As standard, STORZ couplings come with a vacuum resistant lip seal designed for suction-delivery hoses. The couplings for delivery hoses (with a short hose tail) have a seal that is not resistant to vacuum. Aluminium STORZ couplings are fitted with a standard white nitrile rubber seal (NBR), brass couplings with a black NBR seal and [...]
STORZ couplings can be classified by the type of connection and material. The most common connection ends: STORZ coupling with a tail for suction-delivery hoses, STORZ coupling with a tail for delivery hoses, STORZ coupling with a smooth tail to mount a safety clamp, STORZ coupling with a female thread, STORZ coupling with a male [...]
The size of a STORZ coupling can be verified by measuring the distance between lugs (measured on the inside). Distance between the lugs: 31 mm, 44 mm, 51 mm, 66 mm, 81 mm, 89 mm, 105 mm, 115 mm, 133 mm, 148 mm, 160 mm, 188 mm, 220 mm, 278 mm. The most popular sizes: [...]
STORZ couplings are couplings designed for fluid and bulk transfer systems. They are used in firefighting, irrigation systems, chemical industry, food industry, agriculture, etc. The couplings feature symmetrical locking heads (no male/female difference) Therefore, they can be easily connected by turning them by 22°, either manually or with a spanner. It is important to connect [...]
