Male PVC-U screw-in spline socket PN16: The perfect junction between rigid and flexible tube

The male PVC U threaded barbed socket, also known as a barb fitting or hose holder, is the indispensable technical part for connecting a flexible (flexible) hose to a rigid screw-on installation. Designed to provide a secure connection under pressure, this screw-in male model is certified to withstand a pressure rating of 16 bar (PN16). It is the ideal accessory for sprinkler systems, pump outlets or filtration circuits that require a removable connection or flexible termination.

A robust link for hybrid networks

The manufacture of this PVC-U (unplasticized polyvinyl chloride) sleeve guarantees excellent mechanical strength and stability against vibrations induced by the passage of water. Its PN16 certification makes it suitable for professional pumping and water treatment installations. Unlike standard plastic fittings, the PVC-U barbed sleeve provides superior rigidity that prevents crushing or deformation when tightening the clamp on the hose.

Spline design and modularity of the gas thread (BSP)

The screw-in male barb fitting is distinguished by its specific profile optimized for tightness and versatility:

• "Fir" profile: The successive splines ensure maximum grip inside the flexible hose, preventing any tearing under the effect of hydraulic pressure.

• Anti-corrosion resistance: Completely insensitive to limescale, salt and chemicals (fertilizers), it outperforms brass or galvanized steel sockets, avoiding any risk of oxidation that could damage the pipe.

• Standard thread: The Gas Screw Thread (BSP) allows the socket to be screwed directly into a sleeve, tee or threaded valve without gluing.

Installation and professional sealing advice

To guarantee a PN16 performance without any leakage at the junction, the installation must be carried out methodically on both parts of the fitting:

1. Thread side: Apply PTFE (Teflon) tape or a specific sealing wire to the male thread before screwing it into the rigid element. Tighten tightly but not excessively.

2. Spline side: Push the hose along the entire length of the socket. To make insertion easier, you can soak the end of the hose in hot water.

3. Safety: It is imperative to use a stainless steel hose clamp (Serflex type) to block the hose on the splines. Position the collar between two notches for optimal effectiveness.

Areas of application: Irrigation, Basin and Industry

This male spline socket is a standard for connecting lift pumps, water jet systems and pond waterfalls. In the agricultural sector, it allows drip lines or mobile garden hoses to be connected to fixed water inlets. Its food neutrality and structural robustness also allow it to be integrated into industrial fluid distribution networks where the flexibility of a flexible hose is required for filling tanks or cleaning process areas.
