Main side connection Heatpex 125/160 ARIA (plumbing accessory)

Main side connection Heatpex 125/160 ARIA is a plumbing accessory designed to provide a side inlet or outlet for ducting and piping systems with nominal diameters 125 mm and 160 mm. It enables a controlled transition between the main run and a side branch, suitable for use in HVAC, ventilation and drainage systems where a secure lateral connection is required. The component is intended for installation in new builds or replacement work and is compatible with standard ducts and pipes of the specified diameters.

Advantages

The side connection offers a reliable mechanical joint for transferring air or fluids between a main pipe and a branch line while maintaining flow continuity. Its dimensions are matched to common 125 mm and 160 mm duct sizes to simplify integration without extensive modification. The design reduces the need for custom fittings and supports straightforward alignment and sealing during installation.

Suitable for (tasks / use cases)

• Creating lateral branches in ventilation and HVAC ductwork
• Adding side outlets for drainage or conduit systems
• Replacing worn or damaged side connections in existing installations
• Retrofit projects where connection between different nominal diameters is required

Key specifications

• Compatible nominal diameters: 125 mm and 160 mm
• Function: side inlet/outlet connection for ducts or pipes
• Application areas: HVAC, ventilation, drainage systems
• Material: corrosion-resistant plumbing-grade material suitable for fluid and air handling (as per manufacturer specification)
• Connection type: lateral branch designed for secure jointing with standard ducts and pipes

How to use

Select the appropriate orientation so the side connection aligns with the main duct or pipe and the branch run. Prepare the mating pipe ends by cleaning and deburring to ensure a smooth fit. Insert the main duct into the primary opening and the branch pipe into the side port, then apply the recommended sealing method—such as gasket, sealant or clamp—compatible with the materials in use. Verify alignment and secure mechanical fastenings as required by local practice or project specifications, then test the assembly for leaks and proper flow.

Usage recommendations

Use compatible sealing materials and check compatibility with the transported medium (air, condensate, wastewater) before installation. Follow local building codes and manufacturer guidelines for jointing methods and load support. For long runs or pressure-bearing systems, provide appropriate supports near the connection to avoid undue stress on the joint.
