Adapting JIC from 3/8” to 1/2”?

[Todd727]

This is Parker's fittings catalog. It is a great resource to help you when looking for fittings and converting from one size/type to another.

I have bought lots of products from Surplus Center and like them a lot.
But when I wanted to convert all the hoses on my MF400 crawler restoration to jic, from BSPP to jic I used Hose and Fittings.com. Best selection I have found.
I did buy the hoses from Surplus Center however but they didn’t have those adapters. Look at the photos on “anther restoration “ you will see the adapters.

Its more like bending conduit since you cannot really undo the bend, and your trying to line everything up. For 1/2" I use carbon steel or stainless seamless tubing.

To bend it I use a Parker #8 sliding block. For larger tubing I use geared Ridgid benders.
To flare it I use a Ridgid 377 that has an eccentric head so it is not trying to flare all the tube at once.
To cut it I use a Ridgid 15-SI cutter with the correct wheel for stainless
To deburr it I use a Ridgid 223S.


To put a fitting on the end you have two main options:
Flareless.
These are bite to tube fittings, you cut the tube, deburr it, then clean the outside, slide it on then tighten the collar. The advantage of this is that you can get lots of different types of threads, the downside is they are expensive and bulky.

Flared fitting.
Your mostly limited to female JIC 37 degree, or SAE 45 degree of the size that your tube is. They are cheap, and compact. Downside is that the require special tools to make, and you are limited on thread options.

Also I suck at it. Buy 3x the tubing I need and cuss at it the whole time as I fill the scrap bin. Having the right tools does not mean your an expert.

Would those flareless fittings accommodate some variability in the pipe lengths? With hard lines, that's what I'd be most worried about since they all need to start and end in the same plane. I suspect that would be really difficult to get right when flaring the ends.
