Malleable Cast Iron Male-Male Nipple with Black Heart

Malleable Cast Iron Male-Male Nipple with Black Heart

The Malleable Cast Iron Black-Core Male-Male Nipple is an essential fitting, designed to establish a simple and secure connection between two female components or fittings. Acting as an extension or junction adapter, this nipple is the ideal solution for professionals who need to assemble piping pieces and ensure the tightness of the network. Its malleable cast iron design gives it superior mechanical strength, which is essential to maintain the integrity of the installation, even under pressure and expansion stresses. It is a basic but essential part to ensure the continuity and reliability of any fluid transport system.

Functional Versatility for Fluid Dispensing

Versatility is a key feature of this nipple. It is perfectly suited for the distribution of water, gas, steam, as well as any other non-corrosive liquids and gases. Its use is common in the industrial, commercial and residential sectors, especially for HVAC (Heating, Ventilation and Air Conditioning) systems, where a reliable connection is paramount for energy efficiency. Beyond these technical applications, the malleable cast iron nipple with a black heart is very popular in the field of decoration. It is integrated into the creation of industrial furniture – shelves, coat hooks or lighting – where its raw look and black finish give a highly sought-after vintage aesthetic.

Manufacturing Quality Meets Standards

The quality of this fitting is the result of production framed by strict industry standards. The parts are manufactured in full compliance with European and international standards, namely EN 10242 and ISO 49, which guarantees their compatibility and performance. The material used is malleable cast iron EN-GJMB-350-10, as required by EN 1562. This material is selected for its excellent compromise between strength and ductility, ensuring that the fitting can withstand shocks and pressure variations without fail.

Advantageous Waterproofing and Protective Finish

The effectiveness of this nipple lies in its sealing design and surface protection.

• The fitting has two tapered male threads (R) that meet ISO 7-1 (BSPT) standard. This type of thread is specifically designed to fit into a cylindrical female thread (Rp), creating a mechanical tightening compression seal .

• To ensure optimal durability , the fittings have a black finish applied with a minimum thickness of at least 70μm (micrometers). This protective layer against corrosion is essential to preserve the integrity of the cast iron over time and maintain the aesthetics of the fitting.

• The commitment to quality is unwavering: each fitting is 100% tested to guarantee its watertightness. This unit check ensures that the part is ready for installation without any risk of leakage.

Tips for Optimal Use and Installation

To maximize the performance and longevity of this Male-Male nipple, it is important to follow a few assembly rules:

• Preparation of the Waterproofing: It is imperative to apply a quality PTFE (Teflon) tape or a specific gasket paste for the conveyed fluid to the two tapered male threads (R) before insertion into the female fittings.

• Proper tightening: Tightening should be firm and continuous, using the appropriate tools (claw wrenches, wrenches). It must be sufficient to engage the tightness by compressing the threads, without being excessive to the point of weakening the cast iron.

• Post-installation verification: After assembly, especially for pressurized networks (gas, steam), it is crucial to check that there are no leaks.

• Decorative Use: For the creation of industrial furniture, the black finish can be left raw. For a more polished appearance and better hold over time, the application of a protective wax or a matte varnish is recommended.
