Mixed elbow for gluing and threading 45° female / male in PVC

Mixed elbow for gluing and threading 45° female / male in PVC (Reference: 5044)

The Ezfitt mixed elbow represents a major innovation in PVC PN16 fittings. This hybrid piece intelligently combines two connection technologies: gluing according to EN 1452 standard and threading compliant with ISO 228-1 standard. This dual functionality makes it an essential element for professionals and individuals wishing to carry out complex installations with a single reference.

Applications and use cases

This 45° mixed elbow finds its place in many industrial and domestic configurations. It is particularly appreciated in water treatment installations, swimming pool circuits, agricultural irrigation systems and industrial networks. Its mixed design allows easy connection of a glued PVC pipeline to equipment with male threading, thus avoiding the use of multiple adapters.

Plumbing professionals frequently use it for pump connections, valves, flow meters or to connect temporary equipment to permanent installations. The 45° angle allows creating smooth derivations that minimize pressure losses and optimize hydraulic flows.

Technical characteristics and materials

Manufactured in PN16 quality PVC-U, this elbow offers exceptional pressure resistance up to 16 bars at 20°C. The PVC-U material (unplasticized Polyvinyl Chloride) guarantees excellent chemical resistance and optimal durability over time. The service temperature ranges from 0°C to 60°C, thus covering the majority of common applications.

The female side is designed for gluing connection complying with EN 1452 standard, ensuring a permanent and watertight bond with PVC pipes. The male side features an ISO 228-1 gas thread (cylindrical thread) that guarantees reliable connection with standard market equipment. This dual certification ensures compatibility with all European components.

Available in 50mm, 63mm diameters, this elbow adapts to the most commonly used pipelines in medium and large installations. The precise geometry of the 45° angle is obtained by high-precision molding, guaranteeing smooth flow and perfectly repeatable dimensions.

Installation and implementation

Installing the Ezfitt mixed elbow requires following specific procedures for each type of connection. For the gluing side, use an EN 1452 approved PVC cement. After chamfering and degreasing the surfaces, apply the cement uniformly and proceed with fitting by making a quarter turn to distribute the adhesive.

For the threaded side, use an O-ring or PTFE tape to ensure sealing. Tightening must be progressive and moderate to avoid deformation of the PVC thread. Excessive tightening torque could damage the fitting. It is recommended to use appropriate wrenches and avoid impact tools.

Before commissioning, always perform a progressive leak test. Build up pressure gradually and visually check for the absence of leaks. The ambient temperature during installation must be between 5°C and 35°C to optimize the properties of PVC and adhesives.

Expert advice and optimization

To maximize your installation performance, combine this mixed elbow with other components from the Ezfitt range. PVC repair couplings, eccentric reducers and branch tees from the same series guarantee perfect homogeneity of your network.

In outdoor installations, protect the fitting from direct UV rays with a sheath or anti-UV paint. Although PVC-U is naturally resistant, this precaution considerably extends the installation's lifespan. For industrial applications, provide a thermal expansion system adapted to temperature variations.

Professional tip: when replacing a traditional elbow with this mixed model, take the opportunity to integrate a drain point or a control point on the threaded part. This simple modification greatly facilitates future maintenance of your installation. Avoid multiple closely spaced elbows that create significant pressure losses; favor large curves when space permits.
