Unidelta PP Compression Fittings | Connection Guide

Unidelta PP Compression fittings are designed for connecting polyethylene pipes with an outside diameter from 16 to 110mm (200mm for clamp saddles). These fittings ensure a perfect hydraulic seal in the construction of pressurised distribution systems. They are fully compatible with all PELD, PEHD, PE40, PE80 and PE100 pipes. Normally they are used to convey drinking water and fluids at pressures up to 16 bar for generic application. The material used makes these fittings resistant to etching by numerous chemical substances and UV-rays.

The Unidelta Universal Fitting can be used to connect systems using PE metric piping with existing pipes made of any material, with external diameters of 15-34mm.

How to install Unidelta PP Compression Fittings

1. Cut the pipe squarely using pipe cutting tools or circular or band saw. It is advisable to use a guide box to ensure a square cut.

2. Eliminate any burrs and bevel the end of the pipe to facilitate easy assembly and to prevent damage to the fitting gasket. The outer surface of the pipe must be free from imperfections or indentations where the body of the fitting makes contact with the pipe.

3. Unscrew the blue nut and put it onto pipe followed by the white clamping ring. Make sure the clamping ring is in the correct position, with the largest diameter facing the fitting.

4. Press the pipe axially into the fitting, past the gasket, until it touches the internal register inside the fitting body.

5. Tighten the ring nut by hand and then use the torque wrench provided. The ring nut must be tight, but it does not need to reach the end of the fitting body.

Advantages of Unidelta PP Compression Fittings     

• It is faster to install
• It is easier to install, even in difficult working conditions
• 100% safety that pipe has reached internal fitting stop as it is possible to see it
• The best hydraulic seal resulting from the usage of the o-ring typical of the Unidelta compression fitting that is safely pushed in its right position
• The best mechanical seal resulting from the peculiar design and the mechanical pushing system of the fitting internal rings that allow a perfect grip on the pipe in whichever position.
