Alternative for Hygger 1-3/4 Outlet Fitting

[almighty59]

I'm using a Hygger 915-10000 and the outlet uses a 1-3/4 nut in which different size adapters are placed inside of. The pump only comes with one 1-1/2" barbed connection and I'm trying to attach two 1-1/2" connections without using a reducer to increase the size. Hygger doesn't sell replacement/extra fittings so instead I was trying to find a 1-3/4" something that I can screw on both outlets instead that I can reduce to 1-1/2". I know 1-3/4" is not a pipe/hose size so am I out of luck or what else can I use?

You're going to have to think outside the box for 1-3/4" fittings. Off the top of my head, there are automotive radiator fittings that are 1-3/4" but they're usually aluminum threaded or plastic barbs, I don't think I've seen plastic threaded fittings. Also this assumes that Hygger went with some sort of standard thread size so you'd want to measure the thread dimensions, the turns per inch, to see if it matches up with anything.
