End Connections

Fixed (Integral) Rubber Flanges

Fixed Flanges provide quick, economical and hard-wearing connections in medium to high pressure applications. The reinforcing plies and tube liner are melded to the outer diameter of the steel flange to securely seal connections between the hose and other fittings. The flange can also be enclosed with reinforcing ply and rubber as a safeguard in corrosive applications.

Beaded (Rotating) Flanges

Beaded Flanges allow the flange or hose to be rotated in situ. This allows ease of bolt hole alignment and better management of abrasive wear to optimize hose life.

Spigot Flanges

Reinforced Spigot Flanges are especially suited for high pressure, heavy duty applications in mining and dredging. They consist of an in built tail over in which the tube liner, reinforcing and outer cover are vulcanized so that the hose is able to withstand substantial end pull and movement.

Double Flanges

The Double Flange comprises twin steel flanges at each end of the hose and incorporates rubber mouldings to ensure a secure seal from hose to fittings. Stronger than a standard fixed flange, the double flange is the ideal solution for hoses subject to significant movement.
