Clamp Unions

BS4825 Pt 3 Clamp unions – These hygienic unions use two ferrules clamped together with a sealing ring to form a hygienic union. The two ferrules have a tapered flange which when compressed by the clamp forms a tight hygienic seal. Clamp unions are ideal for hygienic applications and are widely used within the food and beverage industries. BDE keeps large stocks and can be supplied next day either as complete union or individual components.

The clamp can be removed by hand using the wing nut, no spanners required.
This is particularly useful where the product line needs to be checked frequently.
