Optimize the modularity of your hydraulic installations with this high-performance brass fitting (or reduction ring). Designed for general plumbing and drinking water networks, this technical fitting reduces the diameter of a female thread to accommodate a smaller male fitting, ensuring a compact and secure transition within your distribution circuits.

Design certified for human consumption

Sanitary safety is the top priority for this fitting, which meets the most stringent standards for your drinking water networks:

Material Brass CW617N: Use of a noble, robust alloy perfectly suited to transporting water intended for human consumption, avoiding any contamination by heavy metals.
Sanitary Compliance: Fitting strictly complies with the amended decree of May 29, 1997, guaranteeing the total harmlessness of the material for your health.
Manufacturing Excellence: Forged and machined or professionally turned, with a homogeneous, porosity-free structure and surgically precise threads.

Professional sealing and PN 16 Bar resistance

The architecture of this reduction fitting has been designed to withstand high pressure stresses while facilitating unobtrusive technical installation:

Wide gasket spans: Male and female spigots have wide, flat spans, guaranteeing optimum flat gasket sealing (min. thickness 1mm) without risk of gasket shearing.
High-pressure: Certified for a nominal pressure of 16 bar (PN 16), this fitting is ideal for domestic, collective or industrial networks under constant pressure.
Ergonomic tightening: The retaining plates are dimensioned to fit perfectly with the wrenches on the market, enabling efficient tightening even in the most cramped configurations.

Simplified installation and maximum discretion

Installation is quick andeasy. Unlike a conventional reduced nipple, the sleeve fits almost entirely into the female fitting, saving considerable space. Thanks to its standard ISO 228-1 "G" thread (BSPP Gas series), it is fully compatible with all valves, pumps and manifolds on the market. Its thermal resistance can be adapted to your installation according to the type of seal chosen (PTFE, fiber or glue), enabling it to be used on cold or hot water.

Case studies : Adapting pumps and manifolds

In a concrete example of garden pump installation, the sleeve allows a 1/2" pipe to be adapted to a 3/4" pump body inlet in a very compact way. For example, it's ideal for inserting a pressure gauge or temperature probe into a plumbing tee without creating unnecessary extra length. Its sturdiness also makes it the preferred choice for connecting drinking water filtration or treatment systems.

Technical sheet

Summary #1: Maximize the modularity of your hydraulic installations with this high-performance brass furring (or reduction ring). Designed for general plumbing and drinking water systems, this engineered fitting allows you to reduce the diameter of a female tap to accommodate a smaller male fitting, ensuring a compact and secure transition within your distribution circuits.
Summary#2: Health safety is the absolute priority of this fitting, which meets the most demanding standards for your drinking water networks: CW617N Brass: Use of a noble, robust alloy perfectly suited to the transport of water intended for human consumption, avoiding any contamination by heavy metals. Sanitary compliance: Fitting strictly in accordance with the amended decree of 29 May 1997, guaranteeing the total harmlessness of the material for your health. Excellent Manufacturing: Product forged and machined or from professional bar turning, offering a homogeneous structure without porosity and threads of surgical precision.
Summary#3: The architecture of this reduction furring has been designed to withstand high pressure constraints while facilitating discreet technical installation: Wide joint spans: The male and female end caps have flat and wide stakes, guaranteeing optimal flat joint sealing (min. thickness 1mm) without the risk of joint shearing. High Pressure: Certified for a nominal pressure of 16 Bar (PN 16), this fitting is ideal for domestic, collective or industrial networks under constant pressure. Ergonomic clamping: The holding plates are sized to fit perfectly on the keys on the market, allowing efficient tightening even in the tightest configurations.
Summary#4: Installation is quick and easy. Unlike a conventional reduced nipple, the fur fits almost completely into the female fitting, saving a lot of space. Thanks to the ISO 228-1 standard "G" thread (BSPP Gas series), it ensures full compatibility with valves, pumps and manifolds on the market. Its thermal resistance adapts to your installation according to the type of waterproofing chosen (PTFE, fiber or glue), allowing use on cold water or domestic hot water.
Summary#5: In a concrete case of garden pump mounting, the furring allows a 1/2" hose to be fitted to a 3/4" pump housing inlet very compactly. For example, it is ideal for inserting a pressure gauge or temperature probe into a plumbing tee without creating unnecessary overlength. Its robustness also makes it the preferred choice for the connection of filtration or drinking water treatment systems.
