Male-Female PVC-U Screw-in Reduction PN16: The compact high-pressure adapter

The Male-Female Threaded PVC-U Reduction, often referred to as MF Reduction or Thread Reduction, is the essential precision fitting for switching from one diameter to another in a tight space. Designed to fit directly into a tapped element (female) to provide a smaller diameter outlet, this model is certified to withstand a pressure rating of 16 bar (PN16). It is the ideal solution for adapting manifold outlets, filter housings or valves without increasing the size of your piping.

A robust transition for optimized hydraulic networks

The manufacture of this reducer in PVC-U (unplasticized polyvinyl chloride) guarantees perfect structural stability under high hydraulic load. Its PN16 certification makes it suitable for professional pool, irrigation and water treatment installations. Unlike larger reduced sleeves, the Male-to-Female reduction allows for an almost instantaneous diameter transition at the outlet of a piece of equipment, thus providing valuable compactness in cramped technical rooms or sprinkler manholes.

Gas Thread Modularity (BSP) and Chemical Resistance

The MF screw-in reducer is particularly popular for its ability to serve as a direct adaptation interface between different components:

• Maximum space saving: The male part is screwed entirely into the larger diameter fitting, leaving only the reduced female outlet visible.

• Anti-corrosion resistance: Completely insensitive to limescale, pool salt and chemicals (fertilizers, light acids), it ensures a much longer lifespan than brass or galvanized steel reductions.

• Versatility: Allows small diameter accessories (pressure gauges, probes, injectors) to be easily mounted on larger main pipes.

Installation and professional sealing advice

To guarantee a PN16 performance without any leakage, the installation of this reducer must be carried out with particular attention to the threads:

1. Preparing the Male Thread: Fill the outer thread with PTFE (Teflon) tape or a specific sealing wire before inserting it into the destination female element.

2. Screwing and Centering: Engage the reduction by hand to check the correct alignment of the threads. The female part of the reduction will then receive the element with a smaller diameter, which has also been sealed beforehand.

3. Controlled tightening: Use a suitable open-end wrench or strap wrench on the hex drive provided. A firm clamp is required to compress the joint or tape, but never overforce the receiver connection should be cracked.

Areas of application: Swimming pool, Watering and Industry

This Male-Female reduction is a standard for the integration of control accessories into swimming pool filtration circuits. In the agricultural sector, it allows micro-sprinklers or drip lines to be connected directly to master lines. Its sanitary neutrality and structural robustness also allow its integration into industrial fluid distribution networks where precise calibration between measuring instruments and piping is common.
