the only threaded pump housings are 1/2" NPT male, or 1/2" BSP male (but I'm not so sure looking at the thread)
you really want to put a 1/2" NPT by barb on the pump ?
kinda biggish I think
the only barbed sizes are 1/2" and 3/4", no 3/8"
we are exploring other options, but molded parts take time and $
this arraignment is not as bad as it may appear, the fill-and-bleed kit is no more
its replacement,
the MCRES-525 has 3/8" NPT ports which permit a 1/2" barb for the line to the pump inlet, or even a 5/8" barb for a true 1/2" ID system
- then the reducing adaptor to 3/8" is only on the pump discharge for our kits
