Wall penetration Heatpex Przejście ścienne 125 (DWZ) (PWE) – Heatpex 711000125

Heatpex Przejście ścienne 125 (DWZ) (PWE) is a wall penetration fitting designed to create a standardized 125 mm opening for routing pipes, conduits or cable bundles through masonry or partition walls. Manufactured by Heatpex, this product provides a consistent sleeve geometry that simplifies installation of HVAC, plumbing and electrical systems where a defined through-wall passage or sealing point is required. The fitting is suitable for new construction and retrofit work where a robust, repeatable wall sleeve helps maintain alignment and simplifies sealing and finishing around penetrations.

Advantages

The Heatpex wall penetration ensures a uniform 125 mm passage size, enabling straightforward insertion of pipes and conduits and reducing on-site modification. Its standardized shape supports efficient sealing and firestopping solutions and helps preserve wall integrity during installation. The fitting promotes reproducible installation details across multiple penetrations, which reduces labor time and potential rework.

Suitable for

• Routing HVAC ducts, condensate and refrigerant lines through walls
• Plumbing pipes and drainage lines in residential and commercial buildings
• Electrical conduits and cable bundles requiring a defined through-wall sleeve
• Retrofit and new-build projects where consistent penetration geometry is needed

Key specifications

• Nominal penetration diameter: 125 mm
• Application: wall penetration sleeve for pipes, conduits and cables
• Compatibility: suitable for masonry, concrete and partition wall installations
• Function: provides a defined through-wall opening to simplify sealing and finishing

How to use

Position the Heatpex wall penetration in the desired location of the wall prior to wall finishing or cut the wall opening to match the nominal 125 mm diameter. Ensure the sleeve is aligned and level with adjacent building elements. Insert the sleeve into the wall aperture and secure according to site practice or manufacturer guidance, maintaining the correct orientation. Once fixed, route pipes, conduits or cables through the sleeve and complete sealing and firestopping measures as required by the project specification and applicable regulations.

Usage recommendations

Verify wall thickness and substrate type before installation and select appropriate fixings and sealing materials. Use compatible sealing or firestop products to meet fire-resistance and airtightness requirements. For installations involving insulated or vibration-sensitive services, allow suitable clearance and provide additional sleeving or protection as needed.
