Male Cap with Galvanized Malleable Cast Iron Stop

Male Cap with Galvanized Malleable Cast Iron Stop

The male plug with galvanized malleable cast iron stop is a first-class closing element, designed to guarantee the tightness and safety of the ends of your piping lines. Its hot-dip galvanizing finish gives it exceptional corrosion resistance , making it ideal for humid environments, outdoor installations or networks carrying sensitive fluids. It is the ideal tool for permanently or temporarily sealing any threaded female fitting, with the certainty of increased durability and reliable performance. The integrated stop simplifies installation by allowing the optimal clamping to be achieved.

Functionality and Resistance in Industry and Design

This galvanized cap is designed to excel in dispensing a variety of fluids. It is used in water (including drinking), gas, steam and any non-corrosive liquid or gas. Its high rust resistance makes it indispensable for HVAC (Heating, Ventilation and Air Conditioning) installations and for outdoor applications. The stop makes it easy to set up quickly and safely. In addition, the silvery and raw appearance of galvanised malleable cast iron is highly sought after in the creation of industrial furniture. This stopper is often used as a finishing piece for legs, tube ends, or decorative structures, contributing to an authentic and solid loft and vintage style.

Normative Compliance and Material Quality

The manufacture of this cap is subject to strict quality controls, ensuring that it complies with professional requirements. The fittings are produced in full compliance with the international standards EN 10242 and ISO 49. The material used is malleable cast iron EN-GJMB-350-10, as required by the EN 1562 standard, which is recognized for its robustness and resistance to mechanical stress. Galvanizing enriches this base by providing long-lasting surface protection, which is essential for the longevity of the product.

Secure Sealing by Tapered Thread and Thrust Gauge

The reliability of this cap is based on the quality of its thread and protective coating.

• The cap is equipped with a tapered male thread (R), which complies with ISO 7-1 (BSPT). This thread is designed to create a high-quality mechanical seal through compression when tightened into a cylindrical female thread (Rp). The integrated stop plays a crucial role in signaling the maximum insertion point, allowing for secure and precise clamping, without the risk of thread damage.

• Hot-dip galvanizing ensures a protective layer with a minimum thickness of at least 70μm (micrometers). This zinc coating is a highly effective anti-corrosion barrier, ensuring the cork's durability in the harshest conditions.

• Excellence is certified: each fitting is 100% tested for tightness when it leaves the factory, ensuring a perfect closure from the moment of installation.

Optimal Installation and Recommendations for Use

To guarantee an effective and long-lasting seal with this galvanized plug, a few steps are necessary:

• Preparation of the Joint: It is essential to apply an appropriate sealant (quality PTFE tape or specific joint paste) to the tapered male thread to optimize the seal seal.

• Clamping with Stop: Screw the cap on until the stop engages. This stop serves as a guide, ensuring that the thread is inserted at the proper depth for sealing without over-tightening.

• Corrosive Environments: Galvanizing protects effectively, but for very aggressive environments (seaside, chemical), regular visual inspection is a good practice.

• Decorative Use: Its galvanized look can be left as is for a raw and elegant industrial look. It can be integrated directly into furniture structures without additional processing.
