Male Cap with Malleable Cast Iron Stop with Black Core

Male Cap with Malleable Cast Iron Stop with Black Core

The male plug with malleable cast iron stop with black core is an essential termination element for securing your piping networks. Designed to permanently or temporarily close a threaded female opening, this plug guarantees an absolute seal thanks to the stop that ensures precise insertion and positioning. It is the solution of choice for professionals looking to seal the end of a line, isolate a section of circuit, or prepare an installation for further expansion. Made of malleable cast iron, it offers mechanical strength that ensures rock-solid reliability for stopping your ducts.

Essential Function in Multiple Application Areas

This male stopper fits perfectly into the distribution of various fluids. It is used in water, gas, steam networks, as well as for non-corrosive liquids and gases. Its sealing function is crucial in HVAC (Heating, Ventilation and Air Conditioning) systems for the decommissioning or maintenance of part of the circuit. The presence of the stop makes it easier to install by providing a clamping mark. In addition, malleable cast iron with a black core is a very popular material in the creation of industrial furniture. This stopper is often used to finish structures (table legs, bar ends) in loft and vintage style, where its raw look and black finish contribute to an authentic and neat aesthetic.

Quality Guarantee: Compliance and Technical Material

This stopper is manufactured to exacting standards of excellence. The fittings are produced and controlled in strict accordance with the international standards EN 10242 and ISO 49, ensuring recognized quality and reliability. The material chosen is malleable cast iron EN-GJMB-350-10, as specified by EN 1562. This material combines strength and lightness, allowing the cap to effectively withstand pressure and thermal stress without compromising safety.

Sealing and Optimal Net Protection

The performance of this cap is based on the quality of its thread and surface protection.

• The plug has a tapered male thread (R), which complies with ISO 7-1 (BSPT). This type of thread is designed to ensure a high-quality mechanical seal by compression when tightened into a cylindrical female fitting (Rp). The integrated stop allows you to reach the optimal clamping point without the risk of over-screwing the workpiece.

• For increased durability and effective rust protection, the fittings benefit from an applied black finish with a minimum thickness of at least 70μm (micrometers). This protective layer against corrosion is essential, especially in the presence of moisture.

• As with the entire range, quality assurance is paramount: each fitting is 100% tested to ensure it is watertight before being delivered, ensuring a perfect seal from the moment of installation.

Assembly Tips and Practical Use

To ensure a secure and long-lasting seal with this cap, following these steps is essential:

• Preparation of the Fillet: Before installation, ensure that the female thread to be plugged is clean and free of debris.

• Sealant: The use of a suitable sealant (quality PTFE tape or joint paste) on the tapered male thread is essential to maximize the seal seal.

• Clamping with Stop: Screw in firmly until the stop comes into contact. The stop serves as a visual and physical marker, helping to prevent over-tightening while ensuring proper insertion for sealing.

• Verification: For pressurized pipes (gas, steam), perform a leak check after final tightening to confirm that there is no leakage.

• Decorative Industrial Use: In furniture manufacturing, the stopper is used to give a clean and aesthetic finish to the ends of the tubes, enhancing the authentic look of the vintage design.
