This single male/female reduction fitting is an essential component for ensuring reliable diameter transitions within your fluid and gas networks. Made of malleable cast iron with a black core (EN-GJMB-350-10), it meets the requirements of EN 10242 and ISO 49, guaranteeing professional quality. Its ruggedness makes it suitable for a wide range of applications, including water, gas, steam and HVAC systems.
Durability is enhanced by a 70μm thick black finish, providing effective corrosion protection. The threads comply with ISO 7-1 (BSPT), with a tapered male (R) and a cylindrical female (Rp) thread, ensuring optimal sealing during mounting. Each part is individually 100% tested to ensure uncompromising reliability of your installation. A quality choice for long-lasting and secure connections.
This simple reduction fitting is the ideal solution for adapting your pipe diameters, ensuring a connection that is both robust and perfectly sealed. Made of malleable cast iron with a black core, this component is a must-have for demanding professionals who work in the distribution of fluids and gases. Built to last, it ensures flawless long-term performance in a variety of industrial and domestic applications. It is the discreet but essential element that ensures the continuity and integrity of your installations.
The quality of this fitting is evidenced by its manufacturing process, which strictly complies with the international standards EN 10242 and ISO 49. The choice of the material, EN-GJMB-350-10 according to EN 1562, is dictated by its excellent mechanical properties, offering optimal strength and malleability. This level of design and control ensures that every part meets the highest expectations for network reliability and security. This is the assurance of installing a proven product that complies with the regulations in force.
To ensure exceptional durability, even in demanding environments, the fitting has a carefully applied black finish. This protective layer has a minimum thickness of 70 μm, acting as an effective shield against corrosion. This superior protection is the key to maintaining the fitting's performance over the years, reducing the need for maintenance and replacement. The initial investment translates into significant savings over the lifetime of your systems.
The practical aspect of this fitting lies in the standardization of its threads. Threaded connections are designed according to ISO 7-1 (BSPT), with a crucial distinction that facilitates assembly and ensures sealing: the male thread is tapered (R) while the female thread is cylindrical (Rp). This configuration is ideal for creating a tight seal when tightening. In addition, the loose nuts used for the unions (not supplied with the reduction alone, but part of the range of compatible accessories) are of the gas type, in accordance with ISO 228-1 (BSPP).
This versatile component finds its place in a multitude of professional application areas. Its ruggedness and waterproof design make it indispensable for:
The distribution of drinking or non-potable water, in residential, commercial or industrial facilities.
Gas networks (excluding direct domestic use, always check local compliance).
Low and medium pressure steam systems.
The transport of non-corrosive liquids and gases.
HVAC (Heating, Ventilation and Air Conditioning) systems, essential for the thermal regulation of buildings.
In particular, it makes it possible to connect a main pipe with a larger diameter to a smaller secondary branch, or to adapt specific equipment to an existing network.
For a successful installation, it is crucial to use sealants suitable for the medium being transported (Teflon, filasse with gasket paste) and to ensure that the thread is tightened appropriately, without excess, so as not to damage the thread.
Here are some concrete examples of use:
Industrial irrigation network : Reduce the diameter after the main valve to feed thinner distribution lines.
Central heating system : Adapting the output of a boiler to the radiator network.
Compressed air circuit : Connect a storage cylinder to a pneumatic tool via a pressure reducer.
Each fitting is subjected to a 100% leak test at the end of production. This individual quality control ensures maximum reliability from commissioning, giving you unparalleled peace of mind.
