Installation Tips:

1. Kair plastic ducting pipe is lightweight & easy to install. You simply push-fit the duct pipe and fittings together. For permanent fixings, you can seal the joints with a method of your choice (Popular options include silicone sealant, solvent cement or tape).
2. Plastic ducting can be carefully cut to the required size using a hacksaw. Offcuts are always useful to keep to hand for joining two male fittings
3. Lengths of duct channel can be joined together using a male connector (Part: "DUCVKC355").
4. Use round pipe fixing clips to fix ductwork to walls and ceilings and support ducting tube (Part: "DUCVKC354C").
5. If your duct run passes through a particularly cold area, we would recommend considering using our pre-insulated ducting to avoid condensation building up within your ductwork. Click here to view our range of pre-insulated plastic ducting.
