Galvanized Malleable Cast Iron Sleeve | F/F EN 10242 for Piping

The Galvanized Reduced Sleeve: the perfect junction for your networks

The Reduced Sleeve made of galvanised malleable cast iron is the essential tool for adapting pipe diameters in complete safety. This female/female fitting creates a strong, watertight connection between two tubes of different sizes. It is the part of choice for the distribution of drinking water, gases, steam, and other non-corrosive liquids or gases, especially in HVAC systems. Its galvanized finish, known for its corrosion resistance, guarantees maximum durability for indoor and outdoor installations.

State-of-the-art manufacturing, guaranteeing EN 10242 compliance

This sleeve is the result of a rigorous design, in full compliance with the European standards EN 10242 and ISO 49. The material used is a malleable cast iron EN-GJMB-350-10 (according to the EN 1562 standard), specifically chosen for its high mechanical strength. The real highlight is its galvanised finish : a 70 μm thick zinc layer is applied to form a reliable corrosion barrier, ensuring exceptional longevity. Each part benefits from a 100% leak test before being put on the market, attesting to its irreproachable quality.

Thread excellence: ISO 7-1 for sealing

To ensure leak-free connections, the thread of this sleeve meets the requirements of the international standard ISO 7-1 (BSPT). This standardization ensures that the two cylindrical female ports (Rp) fit perfectly to the tapered male ends of the pipes. This accuracy is crucial for the safety of your facilities. The EN 10242 standard, which this sleeve complies with, extends to the other components in the range, including loose nuts (ISO 228-1 compliant for gas applications), giving you peace of mind across your entire network.

Areas of application and industrial design

This galvanized reduced sleeve is versatile in various sectors:

• Professional Plumbing: Essential for the transition between different diameters in drinking water, heating or air conditioning networks.

• Industrial Environments: Its corrosion resistance makes it perfect for compressed air, steam and non-aggressive fluid lines.

• Renovation and HVAC projects: It makes it easy to upgrade existing installations by ensuring a reliable and durable connection.

• Interior Design: The raw but clean look of galvanized cast iron is highly prized for creating furniture, shelves or other decorative elements in industrial or loft style.

An investment that secures your networks

The installation of this reduced sleeve is child's play with traditional sealing techniques (filasse, joint paste). By choosing the galvanized version, you are making an investment that minimizes the risk of failure due to oxidation. This fitting is proof that it is possible to combine high-level technical performance with ease of use. It is a sustainable solution that secures and enhances your piping work.
