Equal tee 90° PVC-U female to screw PN16: The modular high-pressure bypass

The 90° PVC-U Threaded Tee is a key piece for hydraulic installations requiring modularity and high strength. Unlike glue-on fittings, this screw-in female-female-female (FFF) model allows for quick assembly and disassembly of your pressurized circuits. Designed to withstand a nominal pressure of 16 bar (PN16), it is the ideal ally for irrigation, water treatment and swimming pool networks where the maintenance or replacement of components must remain simple and efficient.

PN16 robustness and thread accuracy

Made of high-density PVC-U (unplasticized polyvinyl chloride), this fitting is designed for maximum durability. The thread (inner thread) is precision machined to ensure perfect alignment with your male bits. The PN16 certification ensures resistance to a working pressure of 16 bar at 20°C. Its rigid structure does not undergo any deformation under hydraulic load, and its triple female design allows flows to be divided or collected with a net 90° angle, thus limiting internal turbulence.

An ideal alternative to corrosion and bonding

The main advantage of screw-on PVC-U is its complete chemical neutrality. It does not oxidize, does not rust and is resistant to corrosive agents (chlorine, fertilizers, treatment products). Compared to gluing, screw mounting offers valuable flexibility: it allows you to upgrade your system or replace a valve without cutting the pipework. It is the perfect junction connection for connecting pool pumps, filters or tanks whose outlets are often in "Gas" thread (BSP).

Installation and waterproofing: Best practices

To guarantee a perfect seal at 16 bar of pressure, screwing on PVC requires special attention. It is strongly recommended to use PTFE (Teflon) tape or a plastic-compatible sealant on the male threads.

• Expert tip: Screw in by hand first to engage the threads well, then tighten moderately with the wrench (a strap wrench is ideal for PVC to prevent scratches). Over-tightening could crack the tap; the precision of the PVC-U thread ensures a compression seal without the need for forcing.

Applications: Swimming Pools, Watering and Industry

This 90° equal tee is ubiquitous in swimming pool technical rooms for the connection of pressure gauges, probes or injectors. In the agricultural sector, it facilitates the branching of underground or above-ground irrigation networks that must be drained or dismantled for the winter. Its versatility also allows it to be integrated into aggressive industrial fluid transport processes where rapid maintenance is a production imperative.

Thermal resistance and durability

The PVC-U used can withstand fluid temperatures ranging from 0°C to 60°C. Its outer wall is treated to resist common environmental aggressions. By opting for a PN16 screw-in fitting, you are investing in a future-proof part whose mechanical characteristics remain stable over several decades. It is an economical and technical solution for all installers who prioritize the safety of pressurized networks without sacrificing ease of maintenance.
