90° Female-Female PVC-U screw-in elbow PN16: The high pressure right angle

The 90° threaded PVC-U elbow is the essential connection for structuring your piping networks and making perpendicular changes of direction with maximum reliability. Designed for demanding installations, this screw-in female-female (FF) model supports a pressure rating of 16 bar (PN16). It offers a robust and above all dismountable solution, ideal for circuits where maintenance and modularity are priorities.

A reinforced structure for PN16 safety

The high-density PVC-U (unplasticized polyvinyl chloride) construction gives this elbow exceptional rigidity. Its PN16 certification guarantees resistance to the high operating pressures common in pumping systems and water distribution networks. Unlike conventional drain fittings, this pressure elbow is designed to absorb hydraulic stresses without deformation, ensuring a long-lasting seal at the heart of your installation.

The advantages of the screw-in threaded connection

Opting for a 90° elbow to be screwed rather than glued offers incomparable flexibility in the management of your infrastructures:

• Easy maintenance: Allows a section of piping or equipment (pump, filter, valve) to be dismantled without cutting the tubes.

• Total chemical resistance: Insensitive to corrosion, chlorine, fertilizers, and light acids, making it perfect for harsh environments.

• Mounting versatility: Gas pitch tapping (BSP) allows a direct connection to nipples, valves or outlets of metal or plastic tanks.

Installation and professional sealing advice

To ensure a watertight connection under 16 bar of pressure, the installation of this 90° elbow must comply with a few simple rules. PVC-U is a precise material that does not require excessive tightening to be effective.

1. Thread preparation: Wrap PTFE (Teflon) tape around the male thread (in the direction of screwing).

2. Commitment: Initiate the screwing by hand to avoid any thread shift.

3. Final tightening: Use a strap wrench to lock the fitting without marking the material. A good seal ensures that there are no leaks even in the event of network vibrations.

Areas of application: Swimming pool, Irrigation and Industry

This 90° elbow is the centrepiece of the pool technical rooms for the connection of collectors and filtration units. It is also widely used in automatic sprinkler systems and agricultural water supply networks to bypass wall angles or structural obstacles. Its food neutrality also allows it to be used in the transport of fluids in industrial and agri-food environments, where hygiene and sustainability are critical.
