Male/Female Reduced Nipple - Female Superior to Male

Connection Excellence: Brass Reduced Nipple for Gas Threading

The success of any plumbing or heating installation depends on the reliability of its fittings. When professionals need to manage a transition between two pipe diameters, choosing a robust and compliant adapter is an absolute necessity. This Brass Female/Male Reduced Nipple (Ref. 1246) is the ideal solution to ensure a perfect connection and a secure diameter reduction on all your networks. Designed for heavy-duty use, it is the go-to connecting element for fluids, whether for drinking water or other common applications. Our expertise of more than twenty years in the sale of quality fittings allows us to offer you a product that combines compliance, ease of installation and exceptional durability.

Sanitary Compliance and Durability of CW617N Brass

The first requirement of a water-contact fitting is its composition. This nipple is made of CW617N brass, an alloy known for its high corrosion resistance. This choice of material is essential, as it not only ensures an extended service life of the fitting, but also and above all, its compliance. The Mamelon Réduit complies with the amended decree of 29 May 1997, a crucial certification attesting to its suitability for use in water networks intended for human consumption. This compliance makes it indispensable for sanitary plumbing, domestic supply systems, and the distribution of drinking water in the building. Whether the production is based on forging and machining, or high-precision bar turning, the level of quality remains constant.

Optimized Installation for Perfect Clamping

The effectiveness of a fitting is measured by the speed and reliability of its implementation. This reduced nipple has been designed to simplify the work of installers.

• It is equipped with machined holding plates. These flat areas allow for a firm grip with standard wrenches on the market, facilitating positioning and ensuring proper tightening without the risk of deformation or leakage.

• Both bits, male and female, have wide and perfectly flat joint seats. This feature is fundamental, as it creates a maximum contact surface for the seal, ensuring homogeneous compression and, therefore, a guaranteed flat seal seal, even with a minimum thickness of 1 mm.

• The use of the ISO 228-1 "G" thread (BSPP Gas Series) ensures extensive compatibility with existing tubes and equipment.

Performance and Pressure Resistance

The Brass Reduced Female/Male Nipple is designed to operate under common and demanding stresses. Its Pressure Rating (PN) of 16 Bar gives it sufficient robustness for the majority of hydraulic, pneumatic and sanitary applications. It effectively handles the frequent pressure variations in residential and tertiary installations. The temperature versatility of this fitting is conditioned by the choice of sealant: whether it is PTFE tape, elastomeric seal, fiber gasket or gasket paste (glue), it adapts to a wide range of operating temperatures, thus meeting the specifications of your fluid.

Technical Applications and Choice of Dimensions

This reduction fitting is the ideal tool to solve the problems of joining components of different sizes.

Concrete examples of use:

• Heating networks: Adapt the outlet of a central heating manifold (often in 1") to screw in a valve or circulator with a smaller diameter (3/4" or 1/2").

• Instrumentation: Allow mounting of measuring equipment such as a pressure gauge or sensor, which typically has small threads (1/4" or 3/8"), to a wider main pipe.

• Sanitary work: Reduce the size of a water inlet to fit a specific shut-off valve or hose.

• Compressed air: Use the resistance of brass to make the diameter transition on a line of low pressure compressed air.

It is essential to check that the female diameter (ØA) corresponds to the largest size and the male diameter (ØB) to the smallest size to ensure a compliant installation.
