Male-male nipple made of galvanized malleable cast iron

Male-male nipple made of galvanized malleable cast iron

The Male-Male nipple made of galvanized malleable cast iron is an essential fitting for the creation of reliable connections and for the extension of piping lines. It is specially designed to fit into two components or female fittings, ensuring a straight junction and optimal sealing . The hot-dip galvanizing treatment is the major advantage of this product, offering significantly higher corrosion resistance . This feature makes it the preferred choice of professionals for installations exposed to weather, humidity or environments requiring maximum protection against rust and oxidation, guaranteeing exceptional durability .

Improved Performance for Harsh Environments

Thanks to its galvanized finish, this nipple has an expanded field of application to the most demanding conditions. It is ideally suited for water distribution, including drinking water, gas and steam networks, as well as for transporting any non-corrosive liquids or gases. Its corrosion resistance makes it indispensable for HVAC (Heating, Ventilation and Air Conditioning) installations, especially outdoor systems or in damp rooms. Beyond technical uses, the raw and silvery appearance of galvanized malleable cast iron is highly sought after in interior design. It is widely used for the manufacture of industrial furniture – shelves, lighting, loft structures – where it brings an authentic vintage aesthetic and rock-solid strength.

Certified Base Material and Manufacturing Standards

The quality of this fitting is validated by a rigorous production process and compliance with the strictest industrial standards. The parts are manufactured in full compliance with the international standards EN 10242 and ISO 49, ensuring consistent quality and universal compatibility. The base material is malleable cast iron EN-GJMB-350-10, as required by EN 1562, recognized for its excellent mechanical strength and ability to withstand stresses. The galvanizing layer only enhances the intrinsic performance of this cast iron by providing long-term surface protection.

Safety and Reliability: Sealing and Galvanic Protection

The performance of this nipple is based on a combination of precise design and high-quality surface treatment.

• The fitting has two tapered male threads (R), both of which comply with ISO 7-1 (BSPT). This tapered thread is specifically designed to provide a reliable mechanical seal when tightened into a cylindrical female thread (Rp), ensuring leak-free connections.

• Hot-dip galvanizing is applied with a minimum thickness of at least 70μm (micrometers). This zinc coating is a highly effective anti-corrosion barrier, essential for the durability of the fitting in potentially corrosive environments.

• To guarantee excellence, each fitting is 100% tested for tightness when it leaves the factory. This unit check is your assurance of a reliable and ready-to-use product.

Installation Guide for Maximum Longevity

To ensure the tightness and durability of this galvanized nipple, there are a few installation recommendations to follow:

• Preparation of the Waterproofing: It is essential to apply a high-quality sealant (specific PTFE tape or suitable joint paste) to the two tapered male threads before mounting in the female fittings.

• Controlled tightening: Squeeze the nipple tightly. The tightening must be sufficient to engage the tightness by compressing the threads, without excessive force, which could damage the threads or the galvanizing layer.

• Wet Environments: For installations in high humidity or saline environments, periodic cleaning or inspection of the joints is advisable to prevent any risk, even if galvanizing offers robust protection.

• Decorative Use: The galvanized finish can be left as is for a raw industrial look. If you want to keep it over time, a simple regular maintenance is enough.
