Siphon tube (manometer) looped R35 internal/external M20x1.5 L=340 5334610

Siphon tube – protection and reliable measurement

The looped siphon tube R35 is a key element in manometric installations, providing protection for the measuring device against external factors. Its construction, made of corrosion-resistant steel, guarantees long-lasting and trouble-free operation even in harsh industrial conditions. This is an ideal solution for both professional installers and end-users who value precision and durability.

Construction and application

This tube, with a length of 340 mm, effectively separates the manometer from the measured medium. The looped design minimizes the risk of damage caused by high temperature or aggressive substances. M20x1.5 threads (internal and external) allow for universal mounting in various systems. The use of a siphon tube is particularly important in heating, cooling, and ventilation (HVAC) installations, as well as in industrial automation and electrical systems. It protects manometers from rapid changes in pressure and temperature, which translates into measurement accuracy and extends the life of the measuring device.

Advantages for the installer and user

• Manometer protection: The tube protects the delicate elements of the manometer from mechanical and thermal damage – this saves on repair or replacement costs.
• Universal mounting: M20x1.5 threads allow for easy connection to most standard manometers available on the market.
• Corrosion resistance: Steel construction ensures long-term operation even in environments exposed to moisture or aggressive chemicals.
• Effective insulation: The looped design minimizes the influence of medium temperature on manometer readings – precise measurements are the basis for safe and efficient system operation.
• Simple installation: The low weight (approximately 0.5 kg) facilitates the installation and servicing of the siphon tube.
• Compliance with standards: The product comes from a renowned manufacturer WIKA, which guarantees high quality workmanship and compliance with applicable safety standards.
