HDPE Fresh Air Pipe Flange Coupling Quick Connect Butt Joint Adapter

HDPE Fresh Air Pipe Flange Coupling — Quick Connect Butt Joint Adapter

A flange butt-joint coupling for larger HDPE fresh air pipe. Where a simple push-fit becomes hard to seat by hand on big diameters, the flange face gives a positive, bolted connection with consistent compression around the full circumference — and it can be opened again for maintenance without cutting pipe.

Key Features

• Flange butt joint — a positive bolted connection for larger duct sizes
• Good air tightness — even compression around the circumference
• Serviceable — can be opened without cutting the pipe
• Stable fit — resists movement better than a plain push-fit at large diameters
• PP body — corrosion-free and durable
