90° Elbow 88.9 brown / glossy, model 22161XL 353667

90° One-Piece Elbow – Practical Pipe Connection in Heating Systems

The 90° elbow with a diameter of 88.9 mm ensures a quick and secure connection between two pipe sections in a single, compact component. Thanks to its one-piece construction, no additional mounting elements are required – simply fit it onto the prepared connections and secure it. This solution is suitable for both central heating installations and cooling systems, where stability is required at pressures up to 16 bar at 20 °C, and across a wide temperature range from ‑25 °C to 110 °C.

Key Features and Benefits

• Dual-sided connection system – one side is equipped with a compression fitting, enabling quick and leak-tight installation using a wrench or pliers; the other side features a push-fit connector that slides directly into the prepared pipe.
• EDPM rubber sealing – both the gasket and the sealing ring are made of homogeneous EDPM material, resistant to aging and chemical agents, ensuring long-term leak-tightness.
• Bronze material – the connection made of bronze offers high mechanical strength and corrosion resistance, extending the service life of the installation.
• Raw surface finish – the absence of additional coatings allows easy adaptation of the component to specific finishing requirements or further processing.
• Compatibility with system pipes – designed for use in standard pipe systems (system pipe: yes), simplifying component selection for existing networks.
• Thermal advantages – a maximum medium temperature of 110 °C and a minimum of ‑25 °C enable the use of the elbow in a wide range of applications, from underfloor heating to industrial cooling.

Applications and Practical Tips

• Ideal for branching in heating installations, where a precise 90° angle is required while maintaining high operating pressure.
• Suitable for domestic hot water systems, thanks to resistance to temperatures above 100 °C.
• Installation requires no specialized tools – simply fit the compression fitting and push the end onto the connector; the connection is ready for operation immediately after leak testing.
• Thanks to its one-piece design, it eliminates the risk of improper component fitting and reduces the number of potential failure points.

This elbow combines ease of installation with robust construction, making it a universal choice for both professional installers and individuals undertaking their own plumbing projects.
