This is a 1.5" plain male hosetail
They can be glued into 1.5" heat pump unions or solid pipe fittings to allow flexible hose to be connected
The smooth glue side is 1.5" and will glue into a 1.5" fitting
The hosetail side is stepped with 1.25"(32mm) and 1.5"(38mm) sizes to take these size hoses
If you want to glue these into a 50mm outlet, we also sell a 1.5" to 50mm adaptor bush

These bushes glue over the 1.5" end of the hosetail and then are glued into the 50mm outlet
We also sell a 1.5" female hosetail which can be glued onto 1.5" pipe or can be glued to a male hosetail to create a hose joiner
