HDPE Fresh Air Pipe Quick Connect Oblique Tee Ventilation Pipe 45° Y Tee Fitting

HDPE Quick Connect Oblique Tee — 45-Degree Y Branch Fitting

A quick-connect oblique (45-degree) tee for HDPE fresh air pipe. The shallower branch angle produces a smoother airflow path and lower pressure loss than a square tee, which matters on longer runs and is good practice for noise reduction. Assembly is tool-free by hand.

Key Features

• 45-degree branch angle — lower pressure loss, gentler airflow transition
• Quick buckle joints — assemble and dismantle by hand without tools
• Reliable sealing — rubber seal on the pipe OD for airtight performance
• PP engineering plastic — corrosion-free, stable and durable
• Standard sizes — 75 / 110 / 160 / 200 mm

Technical Specifications

Typical Applications

• Dividing airflow along a duct run while keeping pressure loss low
• Branch layouts where a 90-degree tee would restrict the run
• Noise-sensitive bedroom and study branches

System Matching

Combine with pre-insulated HDPE ducting, straight quick-connect tees, couplings and manual volume dampers.

FAQ

Q: Why choose 45-degree over 90-degree?
A: A shallower branch angle reduces turbulence and pressure loss, so airflow is quieter and more efficient.

Q: Is the fitting airtight?
A: Yes, the push-fit seal is designed for airtight joints.

Q: Can it be disassembled?
A: Yes, the buckle connection can be released when needed.
