This is a 52-C Storz coupling with a lug distance of 66 mm and 50 mm hose pillar connection. It is made of brass with an NBR (nitrile rubber) seal. The maximum operating pressure is 16 bar (232 psi). The coupling is suitable for temperatures between -40 to 110 °C (-40 to 230 °F).
Storz couplings are used in fire protection systems and industrial applications. Both parts of the Storz coupling have the same head structure, so couplings with the same lug distance can be buckled together.
Note: The hose assembly is carried out using shell hose clamps to EN 14420-3 (DIN 2817)
Pros:
- It is easy to connect a hose to the Storz coupling
- Quick connection and release by twisting 120°
- All couplings with the same lug distance and nominal size are compatible with one another
- It has a rotatable connection, which prevents any twisting of the attached hose
- Suitable for safety clamp connection
Cons:
- Storz couplings have no shut-off function
