45° Female-Female PVC-U screw-in elbow PN16: Modular hydraulic precision

In the design of a pressure piping system, changes in direction are not always at right angles. The 45° threaded PVC-U elbow is the essential accessory for achieving smooth angular deflections, thus reducing turbulence and pressure drops. Designed to withstand a pressure rating of 16 bar (PN16), this screw-in female-to-female (FF) fitting offers a robust and removable technical alternative to traditional glued installations.

Smooth diversion to optimize flow

The 45° angle is particularly popular in hydraulic installations where maintaining a constant flow is critical. By avoiding a sharp 90° turn, this bend limits the friction of the fluid against the walls, thus preserving the power of your pump and the overall efficiency of the system. Its high-density PVC-U construction guarantees perfect structural strength, capable of absorbing water hammer and pressure variations up to 16 bar without the risk of cracking or deformation.

The advantages of screw-in threaded mounting

The use of PVC-U screw-on fittings provides flexibility that gluing does not allow. This 45° female-to-female elbow makes it possible to build fully removable networks, facilitating maintenance, cleaning or circuit modification operations.

• Chemical resistance: Unalterable against corrosion, salts and water treatment products (chlorine, fertilizers).

• Modularity: Ideal for connection to threaded equipment (valves, pumps, filters) or for seasonal installations such as irrigation.

• Waterproofing: Gas pitch threads (BSP) ensure a precise and secure junction when combined with PTFE tape or a suitable seal.

Installation and sealing tips

For a successful implementation on a PN16 network, the quality of the connection is essential. Although PVC-U is extremely rigid, it is still susceptible to over-tightening with metal tools.

1. Preparation: Apply 5 to 10 turns of PTFE tape in the direction of the male thread.

2. Screwing: Initiate the screwing by hand to check the alignment of the threads.

3. Tightening: Finish the tightening with a strap wrench or claw wrench, without overstraining. The geometry of the elbow allows for easy grip for precise angular alignment.

Areas of application: Swimming pool, Watering and Industry

This connection is a standard in swimming pool technical rooms to avoid obstacles or optimise the space around the filter units. It is also widely used in automatic sprinkler systems to adjust the inclination of pipes according to the topography of the land. Its sanitary neutrality makes it perfectly compatible with the transport of drinking water and food fluids, while being robust enough for industrial environments handling aggressive liquids.

Durability and maintenance of PVC-U

PVC-U PN16 is designed for an exceptional longevity often exceeding 30 years under normal conditions of use. It can withstand fluid temperatures between 0°C and 60°C. Unlike metal bends, it is not afraid of electrolysis or limescale. When needed, its screw-on design allows for quick disassembly for unclogging or network inspection without having to cut or replace sections of pipe.
