COR20 to 1" barb... please help

[sanzz18]

So my setup is a Waterbox 220.6 which has 1" vinyl tubing included for the return. With the Neptune Cor20 return pump having BSP fittings instead of NPT, it complicates getting this pump hooked up to a 1" barb fitting. Someone please help me figure this out cause I stood at Home Depot for 30min trying to figure out how to use their 1 1/4" BSP to slip union.

I would get a female 1-1/4 BPS to 1-1/4 NPT. Then use a barb adaptor

The union on the COR20 converts from crazy BSPP to a 1 1/4" slip. Then you just need a 1 1/4" slip to 1" slip reducer, followed by a 1" slip barb.
