Default Coolant Hose Adapter

What are you guys w/ NAs using to step down 3/8 --> 5/16?

I have a banjo w/ a 3/8 hose barb. However, the water fittings on the motor are 5/16.

Every hydraulic place I've called said that's an odd fitting size and don't carry it.

Thanks.

Just get the two brass barbs, one with a male thread on the back, other with a female, stick them together with some teflon tape and BAM you have an adapter.

Like I told you in the PMs when you were interested in buying them, you can use 5/16" hose without a problem. 3/8" is 6/16", so 5/16" just fits on there a little tighter.
That's the way the turbo kits were supplied long ago by FM and BEGi, and still are unless you get SS lines.

All the hydraulic places I called and asked about using 5/16 hose on a 3/8 barb said it would be a bad idea. Something about stretching the weaving so it becomes very weak.

I'll just step it down w/ some adapters.

You aren't running 2000psi through your water lines. Don't be a *****.

Hahaha.

Anyway, I might not be running it w/ 2000psi but I am running it near heat. I'd imagine weakened weaving + heat will likely cause premature hose failure @ the barb. Need to start looking into fire sleeves.
