Immersion Sleeve Afriso 7×8 mm, length 120 mm, model 555004

Afriso immersion sleeve 7×8 mm, length 120 mm, model 555004 is a cylindrical fitting designed to house temperature or level sensors and probes in pipes, tanks or other process vessels. With internal and external diameters of 7×8 mm and a compact 120 mm length, the sleeve provides a stable protective channel that allows sensor insertion and removal without opening or draining the system. The product is intended for applications requiring a small, robust immersion fitting that keeps sensors isolated from the process medium while maintaining reliable thermal contact.

Advantages

The immersion sleeve offers straightforward installation and dependable protection for sensors, reducing downtime during maintenance and sensor replacement. Its slim 7×8 mm profile and 120 mm length make it suitable for compact installations while ensuring consistent positioning and protection against direct exposure to process fluids. The cylindrical design supports good thermal coupling and mechanical stability for accurate temperature measurement.

Suitable for

• Insertion of temperature or level probes in heating, ventilation and air conditioning (HVAC) systems
• Use in industrial process lines and small-diameter piping
• Applications requiring sensor replacement without system shutdown
• Laboratory or pilot installations with limited installation space

Key specifications

• Inner diameter: 7 mm
• Outer diameter: 8 mm
• Length: 120 mm
• Shape: cylindrical immersion sleeve
• Material: corrosion-resistant metal (as supplied for sensor protection)

How to use

Mount the immersion sleeve into the designated port or fitting on the pipe, tank wall or process vessel following the system's mechanical connection requirements. Insert the probe or sensor into the sleeve so that the sensing element aligns with the end of the sleeve for optimal thermal contact. Secure any external fittings or compression fittings as required to prevent movement. For sensor replacement, withdraw the probe from the sleeve and insert the new sensor without draining the system, provided the sleeve mounting is properly sealed.

Usage recommendations

Verify compatibility of sensor diameter and probe length with the 7×8 mm sleeve dimensions before installation. Ensure the sleeve is installed in a location that provides representative measurement and consider additional sealing or strain relief if used in pressurized or corrosive environments.
