Flanged sleeve Inox - 22 R1 1/4" 1609090005

Application in Sanitary and Heating Installations

This component plays a key role in piping systems where a safe and durable connection of stainless steel pipes is required. The 22 mm (DN 20) flange sleeve is designed for installation in circuits requiring corrosion resistance, such as potable water systems, domestic hot water systems, or heating systems. Thanks to the use of stainless steel grade 316 L (1.4404), the component maintains its properties even under difficult environmental conditions, making it indispensable in facilities with elevated sanitary requirements or in locations exposed to moisture and atmospheric chemical factors.

Construction and Controlled Leak Function

A key feature of this solution is the controlled leak function (LBP - Leak Before Press). In the event of improper crimping or seal damage, the system allows a small amount of medium to escape before complete emergency failure of the joint. This is an important safety feature for the installer during assembly work and for the end user, minimizing the risk of flooding and costly repairs.

The sealing is based on a ring made of ethylene-propylene-diene monomer rubber (EPDM), which is characterized by high aging resistance and a wide operating temperature range. The push-fit coupling connection requires the use of dedicated crimping tools, ensuring repeatability and quality of installation in every work cycle.

Materials and Dimensions in Practice

The product is made of stainless steel 316 L (1.4404), ensuring long-term corrosion resistance without the need for additional protective coatings. The smooth internal surface minimizes flow resistance of the working medium, while precise dimensions guarantee correct installation:

• The external pipe diameter is 22 mm (equivalent to DN 20 / R1 1/4").
• The total length of the sleeve is 28 mm, with a working length of 7 mm.
• These proportions ensure optimal pipe insertion into the crimping head, which is a necessary condition for achieving a leak-tight connection.

Thanks to its simple shape and high-quality materials, the component proves ideal as a reliable link in hydraulic systems with elevated safety requirements. This is a solution dedicated to professionals who value durability and installation repeatability.
