HDPE Fresh Air Pipe Quick Connect Reducing Tee Series Ventilation Pipe Reducing Branch Fittings

HDPE Quick Connect Reducing Tee Series — Push-Fit Reducing Branch Fittings

A series of quick-connect reducing tees that let a larger main duct feed smaller branch ducts. Different pipe diameters are common on real projects because main runs are sized for total flow while branches only carry one room's air. The push-fit joints install by hand and stay airtight.

Key Features

• Reduces duct size at the branch — the main run stays large, branches stay compact
• Multiple size combinations — covers the usual 75-200 mm transitions
• Tool-free assembly — push-fit joints, no glue or screws
• Airtight seal — rubber lip seal on the pipe outside diameter
• PP engineering plastic — tough and corrosion-free

Technical Specifications

Typical Applications

• Stepping down from a main HDPE run to smaller room branches
• Concealed residential fresh air ductwork
• Balancing a system where branch sizes differ from the trunk

System Matching

Works with our full quick-connect family: straight tees, oblique tees, straight couplings and reducing couplings.

FAQ

Q: How do I choose the right reduction?
A: Size the main run for total system flow and each branch for its own terminal. Our sales team can confirm the combination for your layout.

Q: Is a sealant needed?
A: No, the push-fit joint seals on assembly.

Q: Are non-standard combinations available?
A: Please enquire — custom size combinations can be quoted.
