Brass Reduced Nipple Male/Male PN16 - Gas Plumbing Thread Fitting

Brass Male/Male Reduced Nipple: The Gas Threaded Connection Expert

In the world of fluids, the need to adapt two female fittings of different diameters is a recurring situation. The Male/Male Reduced Nipple is the ultimate connection tool, designed to make this transition in a safe and sustainable way. Unlike the F/M nipple, which is the junction between a male and a female, this crucial part allows two female elements to be screwed together. Manufactured to the highest standards, this brass fitting is designed for professionals who do not tolerate any weakness in their networks. Its intelligent design and sanitary compliance make it the preferred choice for general plumbing and pressurized drinking water installations.

Robustness of CW617N Brass and Sanitary Certification

The basis for a reliable connection lies in the quality of its material. This M/M Reduced Nipple is entirely machined from CW617N Brass, an alloy known for its resilience to corrosion and durability. This high-quality material ensures that the fitting will maintain its mechanical and sealing properties under a Pressure Rating (PN) of 16 Bar. Crucially, this product complies with the amended decree of 29 May 1997, making it suitable for contact with water intended for human consumption. Whether you work on a domestic network or a collective system, this certification ensures total peace of mind as to the hygiene and potability of the fluid transported. Precise manufacturing, whether from machined forging or bar turning, ensures perfect thread geometry.

Versatile Gas Series Connection and Leak Safety

This nipple has been designed to fit effortlessly into the majority of existing installations. The connection uses the ISO 228-1 "G" standard (BSPP Gas series). This parallel thread is the most common in plumbing for applications that do not require a cone.

• Practical Holding Dishes: Retaining plates are machined directly on the body of the nipple. These surfaces are perfectly matched to standard wrenches on the market, allowing for quick and secure assembly and disassembly. This allows the installer to apply precise torque without damaging the workpiece.

• Superior Waterproofing: Each end of the fitting has a wide, flat joint span. This feature is fundamental because it ensures optimal compression of the flat joint (from 1 mm thick), guaranteeing a reliable and durable flat joint seal between the two connected female elements.

Temperature Management and Seal Compatibility

The versatility of a fitting is also measured by its ability to adapt to different thermal conditions. Although CW617N brass is robust, the maximum fluid temperature will be determined by the sealing material chosen.

• Choice of Waterproofing: The professional can choose the most suitable type of seal: PTFE tape (on threads for secondary seals), elastomeric seal (for common cold/hot water applications), fiber seal (resistant to higher temperatures), or a sealing glue/paste for threads.

• This choice allows the nipple to be integrated into various networks, ranging from domestic cold water to the heating circuit. The fitting itself, supporting a PN 16 Bar, remains the structural highlight of the assembly.

Areas of Application and Reduction Solutions

This Male/Male Reduced Nipple is the ideal transition tool for multiple plumbing scenarios, allowing existing equipment to be reused or connected.

Examples of use:

• Adaptation of Vannes: Connect a large diameter valve or valve (e.g., 1") to a smaller diameter tube or hose (e.g., 3/4"), both of which have female threads.

• Creation of Measurement Points: Insert a reduction fitting before or after a water meter or filter, if both sides are female.

• Network Changes: Allows you to modify an in-line piping connection, where the main line is wider than the extension or secondary start.

• Repair/Maintenance: Replace a defective part by adapting the new part to the existing female threads.
