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.

Muff Coupling Hose
The FLSmidth® Ludowici® LUDOFLEXTM
muff coupling hose is purpose designed
to handle pressure or suction in the
transfer of the most abrasive material
including bulk, slurry and cement.

• Flexible configuration
accommodating split muff
coupling flanges
• Quick installation with ordinary
hand tools and no specialist
machinery required
• Easy field repair to reduce downtime
• Customised hose length cut on-site
to fit a variety of couplings and suit
any application
