DIN 11851 reducers are essential fittings designed to seamlessly connect pipes, hoses, or equipment with differing diameters in fluid handling systems that use DIN 11851 fittings. These reducers allow for smooth transitions between larger and smaller connections, maintaining efficient fluid flow and preventing leaks. Available in both male and female configurations, DIN 11851 reducers provide versatility for various piping layouts and operational requirements, making them widely used in industries like food and beverage, dairy, and pharmaceuticals.
Crafted from high-quality stainless steel, these reducers offer exceptional durability, corrosion resistance, and hygienic properties. The polished, smooth finish of stainless steel minimizes the risk of contamination, making these fittings ideal for systems requiring frequent cleaning and sterilization. Designed to withstand high pressures and temperatures, stainless steel DIN 11851 reducers are well-suited for demanding environments where reliable performance is critical. Available in a range of sizes, they ensure compatibility with various fitting and pipe dimensions, providing a practical solution for systems of all scales
The precision engineering of DIN 11851 reducers ensures a tight and leak-proof connection, enhancing the safety and efficiency of fluid transfer systems. Their robust construction allows for easy installation and maintenance, reducing downtime during system adjustments or repairs. Whether used to adapt existing systems, integrate specialized equipment, or optimize fluid dynamics, DIN 11851 reducers deliver consistent and dependable performance. By offering a variety of sizes and configurations, these stainless steel reducers are a valuable tool for professionals looking to enhance the functionality and reliability of their fluid handling systems.Interested in a Quote?
Advantages of Using DIN 11851 Reducers
-
Connection of Different Sizes
DIN 11851 reducers are designed to connect pipes, hoses, or fittings with different diameters. This allows for seamless integration of components with varying sizes within the same system, making it easier to adapt fluid or gas transfer systems to specific operational needs.
-
Hygienic Design
DIN 11851 reducers are widely used in industries like food and beverage production, dairy, and pharmaceuticals due to their hygienic design. The smooth surfaces and sanitary construction make them easy to clean and sterilize, ensuring compliance with strict hygiene standards and preventing the accumulation of bacteria or contaminants.
-
Leak Prevention
DIN 11851 reducers provide a secure, leak-proof connection between components of different sizes. This is crucial for maintaining system integrity and preventing fluid or gas leaks, especially in hygienic applications where preventing contamination is a priority.
-
Quick and Easy Installation
DIN 11851 reducers are designed for quick and easy installation. Their threaded or clamped design allows for fast and secure connections, minimizing downtime during system setup, modifications, or maintenance, and ensuring a reliable and secure fit.
-
Improved System Flexibility
DIN 11851 reducers provide flexibility to fluid and gas transfer systems by allowing the connection of components with different diameters. This adaptability is particularly useful in dynamic environments, such as food processing facilities or chemical plants, where system configurations may need to change frequently.
-
Enhanced Safety
By providing secure and leak-free connections between components of different sizes, DIN 11851 reducers help enhance the safety of fluid and gas transfer systems. This is particularly important in high-pressure or hygienic environments where leaks could pose significant risks to both personnel and product integrity.

Industrial Hoses
Industrial hoses are robust, flexible tubes designed to convey fluids, gases, or granular materials under varying conditions and pressures. These hoses are employed across a diverse range of industries, including petrochemical, food processing, construction, and manufacturing, to name just a few. Made from materials such as rubber, PVC, or metal, they can be reinforced with layers of textile, wire, or other synthetic materials for added strength and durability.

Clips & Clamps
Hose clips and clamps are mechanical devices specifically designed to secure hoses onto fittings, thereby preventing unwanted fluid leakage or detachment. These components are vital in various applications, such as automotive systems, industrial machinery, and plumbing. Made from materials like stainless steel, plastic, or even heavy-duty rubber, hose clips and clamps can range from simple wire forms to more elaborate quick-release or adjustable types.
