Optimize the maintenance and flexibility of your hydraulic networks with theStraight Male/Female Union with tapered seat (Ref. 222). This high-precision brass "three-piece" fitting is the ideal technical solution for joining two sections of piping, while retaining the possibility of quick disassembly without having to cut or unsolder your existing installations.

Sanitary compliance and 4MS brass technology

The sanitary safety of your drinking water networks is guaranteed by the use of materials that comply with the strictest European standards:

Brass CW617N 4MS: This new-generation alloy complies with the European 4MS approach, strictly limiting heavy metal content to preserve water purity.
Drinking water certification: The fitting complies strictly with the decree of June 25, 2020, validating its use for the distribution and conditioning of water intended for human consumption.
Fluid compatibility: In addition to drinking water, this union is perfectly suited to glycol water circuits and other fluids compatible with brass.

Technical performance and conical sealing

Union Ref. 222 is designed to withstand intensive operating conditions in the plumbing and HVAC sectors:

Nominal pressure 16 Bar: Certified PN 16 robustness to guarantee flawless sealing under constant hydraulic pressure.
Extended temperature range: Capable of operating from -20°C to +120°C, this fitting is equally suited to high-temperature heating systems and chilled water networks.
ISO 228-1 standard: Threads and tappings comply with the BSPP (Gas Series) standard, ensuring universal compatibility with your valves, pumps and piping.

Ergonomic installation and easy dismantling

Installation is easy and maintenance simplified thanks to the three-piece structure. Retaining plates adapted to market wrenches ensure effective, secure tightening. The tapered seat provides a metal-to-metal seal reinforced by compression, while the wide, flat seal seats on the male and female ends also allow the use of traditional flat seals for maximum safety against micro-leaks.

Case studies: maintenance of circulators and boilers

In a concrete boiler room maintenance situation, this straight union can be used to isolate and remove a circulator or valve without dismantling the entire rigid network. For example, when servicing a lift pump, simply loosen the union's central nut to free the device. This is an essential accessory for professional installations where rapid intervention and sanitary reliability are paramount.
