Plastic Ducting Connectors

28 products

Plastic ducting connectors and couplers for joining rigid round and flat ventilation ducting. The range covers Domus round connectors (100/125/150mm), rectangular flat-channel connectors (110×54, 204×60 and 220×90 Megaduct), straight connectors with an integral backdraught damper, hose connectors and spigot connectors with wall plates — for domestic MVHR, extract and supply systems.

Genuine Domus and Quiet-Vent components, UK stock with next-day delivery available. Not sure which connector fits your ducting? Email hello@efans.co.uk or call 0161 818 2050.

Plastic Ducting Adaptors / Flat Plastic Ducting / Duct Connectors & Fittings

What does a ducting connector do?

A connector joins two lengths of the same ducting in a straight line, keeping the run airtight and continuous. Some connectors also carry an integral backdraught damper (spring or gravity flap) that stops air flowing back through the duct when the fan is off — useful on external terminations.

Which connector do I need?

Match the connector to your duct's size and shape: round connectors for 100/125/150mm circular duct, and flat-channel connectors for rectangular systems (System 100 at 110×54, standard flat at 204×60, or Megaduct at 220×90). To change size or shape instead of joining like-for-like, use a ducting adaptor.

When do I want a connector with a damper?

Choose a connector with an integral damper where you want backdraught protection built into the joint — typically near an external wall or terminal — saving a separate damper fitting. For runs that don't need it, the plain straight connector is fine.
