90° elbow with SC 28 brass / polished, model 2216 Sanpress 106348

Change of Installation Direction with Confidence and Durability

In installation systems where tightness and resistance to environmental conditions are critical, the 90° elbow from the Sanpress series, model 2216, serves as a robust link in piping circuits. Made of bronze (or silicon bronze), this component is designed for connecting pipes with an outer diameter of 28 mm. Its one-piece construction eliminates the risk of leaks associated with multi-part connections, which is particularly important in areas with limited installation space. Thanks to the SC-Contur contour, the installer receives a tool that visually signals the correctness of the joint execution – an unpressed connection is immediately visible, preventing errors during system acceptance.

Material and Resistance to Operating Conditions

The material of construction – bronze or silicon bronze – gives this fitting high corrosion resistance, making it an ideal choice for water installations, including potable water and heating systems. The component does not require additional surface treatment (raw state), as the material itself provides sufficient protection under typical operating conditions. Inside each arm, seals made of ethylene-propylene-diene rubber (EPDM) are installed. This material is characterized by excellent resistance to aging and water action over a wide temperature range.

This component operates safely at a maximum working pressure of 16 bar at a temperature of 20°C. The medium temperature range it can withstand is from -25°C to +110°C, allowing its use not only in cold water supply installations but also in heating systems with elevated operating temperatures. The KIWA certificate confirms the product's compliance with rigorous safety standards for water installations.

Practical Aspects of Installation and Operation

Installation of this fitting requires the use of dedicated crimping tools compatible with the V contour (SC-Contur designation). The length of each arm is 56 mm, facilitating precise planning of the pipeline route and maintaining appropriate clearances from walls or other structural elements. The elbow is a symmetrical component – both connections are crimped couplings with a nominal diameter of 3/4 inch (for 28 mm pipe).

It is worth noting several key aspects of using this product:

• Connection safety is ensured by the SC-Contur contour, which allows for quick visual verification of proper crimping – an unpressed joint is immediately visible.
• Sealing durability is guaranteed by EPDM seals resistant to cyclic temperature and pressure changes, translating into long system life.
• Application versatility covers cold and hot water installations as well as central heating systems thanks to the appropriate temperature range.
• Chemical resistance of the bronze material protects against corrosion caused by water and other liquid media in the system.
• Ease of installation results from the one-piece construction, which simplifies the pipe joining process without the need for tightening nuts or using additional sealing elements beyond the factory-installed EPDM rings.

It should be remembered that this product is part of the Sanpress system and must be installed exclusively in accordance with the manufacturer's guidelines for crimping copper or stainless steel pipes (depending on the pipe used in the system). The absence of a drain valve or air vent means that the component serves solely to change the direction of medium flow in closed or open installations. Thanks to its construction and materials, this elbow minimizes the risk of failures resulting from corrosion or mechanical leakage throughout the entire service life of the installation.
