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). Rectangular plastic ducting can be carefully cut to the required size using a hacksaw. Offcuts are always useful to keep to hand for joining two female fittings together. 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.
