25-D (31 mm) Stainless Steel Storz Coupling DN 25 Flange

This is a 25-D Storz coupling with a lug distance of 31 mm and DN 25 flange connection. It is made of stainless steel with an FKM seal. The maximum operating pressure is 16 bar (232 psi). The coupling is suitable for temperatures between -15 to 200 °C (5 to 392 °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:

• Quick connection and release by twisting 120°
• All couplings with the same lug distance and nominal size are compatible with one another
• Stainless steel couplings have excellent corrosion resistance
• This coupling has a DN 25 flange connection

Cons:

• Storz couplings have no shut-off function
