This Kit is a 2" Manifold Coupling Kit for 5+ Manifolds. The Kit consists of (1) 2" Coupler, 2"Slip X 2"Slip (6") of 2" Flex Pipe, (1) 1 Pint or 16 oz of Blue Glue and (1) 1/4 Pint of Purple Primer. The kit is to be used to Connect a New 2" Manifold to old 2" Flex or Hard Pipe and will be enough glue to install 5+ Manifolds. We offer larger glue cans for more manifolds in kits just like this. Whenever you are cutting out a broken manifold you will usually need to extend the main input pipe to keep the manifold close to it's original location as well as Glueing to old plumbing you need to Purple Prime the old pipe Especially Flex because it can shrink up. You would then Blue Glue it and then spin it until it stops. Thats why we offer a Coupler that you can glue and spin to the old pipe then just use normal Glueing techniques when connecting new plumbing to new plumbing.
