SFL Sflue Black Twin Wall Flue Pipe - Tee Cap With Drain

Sflue twin wall flue pipe is manufactured to a very high standard in the UK and is designed to meet the requirements of multifuel appliances. Sflue utilises an eight-barb quick lock jointing system to secure each joint. The components are secured by locating the barbs with a twist of each section. A locking band must then be used at each joint to secure the fixing. Sflue has the end user in mind with it's quick and easy twist lock system as well as very competitive prices, and all from a UK based company.

The Tee Cap With Drain is used to close off the branch or base of a 90° or 135° Tee Piece or for use as an inspection/access component. Also has a 1" BSP external thread drain connection.

Twin Wall Flue Sizing – Please Read Before Ordering

Insulated Twin Wall flue components are always listed by their internal diameter. However, parts that fit around a Twin Wall pipe (such as collars, brackets, bands, and plates) are sized by the internal diameter of the Twin Wall flue they are designed to fit, not the outside measurement of the item itself.

Please select the correct option below:

Select 5” if your Twin Wall flue has a 5” internal diameter (7” outer diameter)
Select 6” if your Twin Wall flue has a 6” internal diameter (8” outer diameter)
Select 7” if your Twin Wall flue has a 7” internal diameter (9” outer diameter)
Select 8” if your Twin Wall flue has a 8” internal diameter (10” outer diameter)

Shipping and Returns

Returns are accepted within 30 days of purchase for a refund. A returns authorisation number must be obtained from us, either by contacting us directly or via an eBay Return Request. Items must be returned unused and in a re-sellable condition for a refund to be issued.

We aim to offer free delivery wherever possible; however, a small number of UK locations incur unavoidable additional charges due to courier hub coverage. If your order is affected, we will contact you on the next working day. These charges are separate from and not calculated by eBay’s postage calculator.

All stoves and larger orders are delivered palletised via a one-man, kerbside delivery service only. This means delivery is made to the roadside, and drivers may refuse access to certain locations depending on site conditions. Customers must ensure sufficient manpower is available to move the pallet from the kerbside to the desired location. This is the customer’s responsibility. Failed deliveries or requests for redelivery may result in additional charges.
