Barb style manifolds work with vinyl or reinforced pipe. Semi rigid pipe does not seal to barbed styled manifolds.
Manifolds can be joined if more barbs are required.
If using ribbed manifold secure pipe in place with clips.
If using smooth manifold secure pipe in place with PVC glue.
I have a number of lengths of 16mm (ID) x 3mm wall rubber hose, which I am trying to join together by use of a manifold. What are the 3/4" manifold barbs true inside and outside diameter, plus effective length?
