Male Male Cast Iron Reduced Nipple - Industrial Gas Plumbing Fitting

Malleable Cast Iron Male-Male Reduced Nipple

The male-male black-core malleable cast iron reduced nipple is an essential connection solution for multiple industrial and domestic applications. This component is specially designed for demanding professionals who are looking for a reliable part for their plumbing, heating or fluid distribution installations. Its robust design allows it to ensure a safe transition between two threads of different diameters, while maintaining the integrity and tightness of the system. As the centerpiece of piping networks, choosing this fitting means durability and peace of mind for any installation that requires managing the pressure and flow of various media.

Application Versatility: Water, Gas, Steam and More

Versatility is one of the major advantages of this reduced nipple. It is particularly suitable for water distribution, whether drinking or industrial, but also for gas, steam and non-corrosive liquid and gas systems. This adaptability makes it a preferred choice in many industries, including HVAC (Heating, Ventilation, and Air Conditioning) systems, where the reliability of fittings is crucial. In addition, the current trend towards industrial furniture offers a new dimension of use. Designers and craftsmen are increasingly integrating it to create shelves, tables or lighting in a loft and vintage style, where the rawness and quality of the materials add a touch of authenticity and solidity.

Standards-Compliant Design and Manufacturing

The quality of this fitting is guaranteed by a rigorous design, manufacturing and control process. The parts are produced in compliance with strict European and international standards, including EN 10242 and ISO 49, ensuring recognized compatibility and performance. The material used is EN-GJMB-350-10, which complies with EN 1562, a malleable cast iron known for its high mechanical strength and ductility. This composition ensures that the nipple can withstand the stresses of intensive daily use without compromising the safety of the installation.

Sealing and Anti-Corrosion Protection

Tightness is a non-negotiable criterion for any fluid connection. For this reason, each reduced nipple is equipped with a tapered male thread (R) in accordance with ISO 7-1 (BSPT). This type of thread is designed to ensure a tight and reliable interlocking. Particular attention is paid to the finish, with a protective coating against corrosion. The fittings have a black finish with a thickness of at least 70μm, an essential protective layer to ensure increased durability in the face of humidity and varied environments. In addition, to ensure that the product delivered is flawless, each fitting is 100% tested for tightness before being marketed, eliminating the risk of leaks on your construction sites.

Implementation and Advice for Optimal Use

To get the best performance from this reduced nipple, it is recommended that you follow a few key steps when installing it.

• Thread Preparation: Always ensure that the threads of the pipes or other fittings to be connected are clean and free of debris or residue.

• Use of a Sealant: Even though the tapered thread is designed for sealing, the application of a quality sealant (such as Teflon or gas/water-specific seal paste) to the male thread is strongly recommended for maximum safety.

• Controlled tightening: Screw the nipple in tightly, but not excessively. The clamping must be sufficient to compress the sealant and ensure metal-to-metal contact without deforming or damaging the fitting. Over-tightening can cause the workpiece to become brittle.

• Alignment Check: Ensure that the hoses are properly aligned before final tightening. Misalignment can induce lateral stresses that reduce the seal and service life of the fitting.

• Furniture Applications: For furniture creation, applying a protective varnish or wax after installation can help preserve the black and matte look against scratches and wear, while enhancing the industrial aesthetic.

This nipple is the ideal tool for professionals looking to switch from one pipe diameter to another with a reliable and compliant reduction part.
