Female/Male Union Fitting in HDPE

The Female/Male Union Fitting in HDPE (Reference: 4730A) from Multitanks represents the ideal solution for all your connection needs in professional and domestic irrigation systems. This specialized fitting allows efficient connection of equipment with different thread diameters, providing maximum flexibility in hydraulic installation design.

Versatile applications for all your projects

This union fitting proves useful in numerous irrigation configurations. It particularly excels when connecting surface pumps to pipes of different diameters, enabling perfect adaptation without flow loss. Professional gardeners appreciate it for connecting drip irrigation systems with traditional watering networks.

In the agricultural sector, this fitting facilitates integration of water meters, filters, or pressure regulators into existing circuits. Its design also enables efficient repair of damaged pipeline sections, avoiding complete system replacement.

Landscapers frequently use this type of fitting to adapt their automatic irrigation controllers to pre-existing installations, ensuring perfect sealing even with different thread sizes.

Technical excellence of HDPE

The choice of high-density polyethylene (HDPE) for this fitting is deliberate. This thermoplastic material presents exceptional characteristics that make it the hydraulic industry standard. Its remarkable chemical resistance enables it to withstand liquid fertilizers, plant protection treatments, and additives commonly used in gardening.

The molecular structure of HDPE provides the fitting with superior UV resistance, preventing premature degradation even during prolonged sun exposure. This property guarantees extended service life, significantly reducing maintenance costs.

The BSP (British Standard Pipe) threads are precision-machined to ensure optimal sealing. The thread pitch strictly complies with international standards, guaranteeing compatibility with all irrigation equipment on the European market.

The particularity of this union fitting lies in its different thread diameters: the female part has a larger diameter than the male part, thus enabling adaptation between equipment with varying specifications.

Simplified installation and reduced maintenance

Installing this union fitting requires no specialized tools. Hand tightening generally suffices to achieve perfect sealing, thanks to integrated O-rings and thread precision. For high-pressure applications, using a strap wrench optimizes tightening without risking material damage.

Before installation, check the cleanliness of contact surfaces and absence of chips or debris on threads. Applying sealing tape (Teflon) to male threads reinforces sealing, particularly recommended for continuously operating systems.

Maintenance is limited to periodic visual inspections to detect potential cracks or deformation. Cleaning is simply done with clear water, without requiring aggressive chemicals that could alter HDPE properties.

In case of frost, this fitting presents excellent thermal variation resistance. Nevertheless, it is recommended to drain circuits during prolonged winter shutdowns to avoid any risk of deterioration.
