38 (51 mm) Forged Aluminum Storz Coupling 25 mm Hose Pillar Rotatable with Lock

This is a 38 Storz coupling with a lug distance of 51 mm and 25 mm hose pillar connection. It is made of forged aluminum 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.

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
• Aluminum couplings are lighter in weight than stainless steel
• It has a rotatable connection, which prevents any twisting of the attached hose
• Locking device to prevent accidental decoupling

Cons:

• Storz couplings have no shut-off function
