Wall - 25x3/4"; PE FIV.07709

Product detailed description

Wall sleeves are essential components in the installation of polyethylene (PE) piping systems, particularly in residential and commercial buildings. They are commonly used in heating, plumbing and irrigation systems where PE pipes need to pass through walls or partitions. Installers and technicians working on such systems must ensure that the connection is both watertight and mechanically stable. This wall sleeve is designed for use in environments where the operating temperature ranges from -20 °C to +90 °C, making it suitable for a wide range of applications including underfloor heating and cold water supply lines.

When installing this type of fitting, the installer must consider the correct sizing and positioning to ensure the PE pipe is securely held and sealed. The brass body provides durability and resistance to corrosion, while the sealing rings ensure a leak-free connection. The sleeve is typically used in conjunction with other fittings and components to complete the piping system.

Technical parameters

Installation and connection

Installation of this wall sleeve involves passing the PE pipe through the sleeve and securing it with the clamp ring and O-rings. The connection sizes must be verified to ensure the PE pipe fits correctly within the sleeve. The installer should check that the O-rings are properly seated and that the clamp ring is tightened to the manufacturer's specifications. Common installation errors include incorrect tightening of the clamp ring, which can lead to leaks, or using the wrong size sleeve for the PE pipe diameter.

Compatibility and accessories

This wall sleeve is compatible with standard PE pipes of the appropriate diameter. It is typically used with other fittings such as elbows, tees and couplings to complete the piping system. When ordering, ensure that the PE pipe and other fittings are compatible with the sleeve's dimensions and material specifications. No additional accessories are required for standard installation.

Technical background for designers

The operating principle of this wall sleeve is based on mechanical compression and sealing. The brass body provides structural support, while the clamp ring and O-rings create a tight seal around the PE pipe. The material properties of brass CW617N and CW614N ensure resistance to corrosion and mechanical stress. The integration of the sleeve into the system depends on the correct sizing and positioning to prevent movement or leakage. The service life and efficiency of the fitting are influenced by the quality of the installation and the operating conditions of the system.

Service and operation

During operation, the sleeve requires no regular maintenance. However, periodic checks should be carried out to ensure the seal remains intact and there are no signs of leakage. If a leak is detected, the clamp ring should be inspected and tightened if necessary. The O-rings should also be checked for wear or damage and replaced if required.

Frequently asked questions

Can this wall sleeve be used with PE pipes of different diameters?
No, the sleeve is specifically designed for a 25x3/4" PE pipe. Using it with a different diameter may result in an improper seal or mechanical failure.

Is it possible to install the sleeve without the clamp ring?
No, the clamp ring is essential for securing the PE pipe and ensuring a watertight seal. Omitting it may lead to leaks or pipe movement.

Can the sleeve be used in systems with higher operating pressures than PN 16?
No, the maximum operating pressure is specified as PN 16. Exceeding this pressure may cause the fitting to fail.

What is the recommended tightening torque for the clamp ring?
The tightening torque is not specified in the technical data. It should be carried out according to the manufacturer's instructions to avoid over-tightening or under-tightening.
