45° elbow with SC 42 stainless steel - stainless / polished, model 23261 Sanpress 435431

Application and Installation Characteristics

The Sanpress Inox 45-degree elbow is a component designed for creating direction changes in stainless steel piping systems. Thanks to the use of grade 316 (1.4401) stainless steel, the product exhibits high corrosion resistance, making it suitable for water supply, heating, and process systems where durability in challenging environmental conditions is required. The 42 mm radius allows for a smooth transition between pipes with an outer diameter of 42 mm, minimizing flow resistance compared to sharp bends.

Installation is based on a press-fit system, eliminating the need for welding or gluing. One side of the fitting features a push-in end (plug), while the other is a press-fit coupling – both connections are prepared for crimping with a specialized tool. A key structural element is the EPDM rubber seal, which ensures a leak-tight connection with the first crimp. This allows installers to work quickly, while end-users gain confidence that no leaks will occur at the direction change point under a working pressure of 16 bar at 20°C.

Construction and SC-Contur Technology

This model is distinguished by the use of SC-Contur technology, which enhances safety and ease of installation. The sealing profile is designed to create a leak-proof connection even under vibrations or temperature fluctuations. The fact that the fitting is one-piece and made entirely of stainless steel (including fastening elements) eliminates the risk of galvanic corrosion between different materials.

The connection lengths are precisely selected for joint stability: the "plug" connection reaches 59 mm, facilitating pipe insertion and stabilization before crimping, while the "press-fit coupling" connection is 57 mm long, providing adequate contact surface for the crimping head. This construction allows for quick verification of correct installation – after crimping, no additional tightening or adjustment is required. The absence of a drain valve or air vent means this is a pure connecting element that must be integrated with the rest of the system according to the installation design. The seal material (EPDM) is resistant to aging and the effects of drinking water and heating media, resulting in a long service life for the entire installation without the need for frequent inspections or seal replacements.

Durability and Operating Conditions

By choosing this 45° elbow, you receive a component compliant with Sanpress Inox system standards, ready for immediate installation in pressure systems. The primary material is grade 316 (1.4401) stainless steel, which guarantees chemical and mechanical resistance for pipes with an outer diameter of 42 mm. The direction change angle is exactly 45°, allowing flexible routing of pipe runs in limited installation spaces. The system operates safely up to a working pressure of 16 bar at an ambient temperature of 20°C, thanks to the ethylene-propylene-diene (EPDM) rubber seal. The mounting system is based on SC-Contur press-fit technology, utilizing two types of connections with precisely defined dimensions: one "plug" type at 59 mm and one "press-fit coupling" type at 57 mm. The absence of additional elements such as drain valves or air vents means the fitting serves solely as a connecting and flow-directing component in visible or concealed installations.
