Transition fitting SC 22 x 3/4" stainless steel - stainless / polished, model 2312 Sanpress 436629

Durable Stainless Steel Connection with Thread in the Sanpress System

The Sanpress Inox transition fitting, catalog number 436629, is a key component for connecting stainless steel pipes to traditional threaded installations. Manufactured entirely from stainless steel 316 (1.4401), the product ensures corrosion resistance not only in the base material but also at the connection point, which is critical when working with potable water or heating systems. Thanks to the SC-Contur contour, installation requires dedicated crimping tools, guaranteeing repeatability and leak-tightness without the need for additional gaskets or assembly pastes on the crimping side.

Application and Technical Characteristics

This component serves as a transition from a pipe with an outer diameter of 22 mm to a metric internal thread with a nominal diameter of 3/4 inch. It is a one-piece design, eliminating the risk of leaks caused by loose mechanical elements inside the fitting. The overall length is 50 mm, allowing precise fitting in tight installation spaces.

Key operational parameters result directly from the materials and construction used: the EPDM rubber gasket enables safe operation across a wide temperature range from -25°C to +110°C, while the stainless steel housing withstands a working pressure of up to 16 bar at 20°C. Thanks to the homogeneous construction from stainless steel 316 (1.4401) and the use of an EPDM gasket, this fitting is designed for installations requiring high durability and chemical resistance. Its dimensions – 22 mm pipe diameter on the crimping side and Rp 3/4" thread on the connection side – allow smooth transitions between different connection types within the Sanpress Inox system.

Installation and System Reliability

For the installer, ease of installation and assurance of leak-tightness are paramount. This fitting does not include a drain valve or air vent; it is a simple component intended for permanent pipeline connections. On the crimping side, the SC-Contur contour is used, which, upon crimping, creates both a mechanical and sealing connection simultaneously. The threaded side requires standard tightening using a socket or open-end wrench, with the hexagon on the body facilitating tool grip without risking damage to the stainless steel surface.

The product holds KIWA and VdS certifications, confirming its compliance with rigorous industry standards regarding safety and quality in sanitary installations. The absence of a need for additional Teflon gaskets or tapes on the crimping side reduces installation time and eliminates potential sources of human error during assembly. This solution is dedicated to stainless steel piping systems where aesthetics and durability are priorities.
