I have some upcoming projects that will require a lot of custom length hoses, so I thought it would be a good time to give these a fair trial. I have always had hoses made locally at a fair price and in a timely manner, but I was always curious about these.

All parts (hoses and Fittings) where purchased from Discount Hydraulic Hose. I only needed the 1/4" hose and fittings for this project, but all the sizes are assembled the same way.

This is 30' of 1/4" SAE 100R2AT 2-Wire 5000psi hydraulic hose


Here are two types of fittings, 1/4" NPT on the left, and a -6 JIC on the right.


Better view. 1/4" NPT on the left and -6 JIC on the right.



Here they are with the inner stems removed from the outside collar.


A die grinder with a cutoff wheel makes easy work of cutting the hose cleanly.


Here is the cut hose, a straight clean cut is important.


The outside collar is threaded onto the hose. These are left-hand threads.


Turn it till the inside bottoms out on the hose.


Now, mark the hose/collar, and back off the collar 1/2 turn or so to create a gap inside the fitting for the hose to expand into. This is a VERY IMPORTANT step. Failure to do this will cause the stem to break (Don't ask how I know!)


Hold the collar in a vise, lube the stem and inside the hose with some hydraulic oil and start turning the stem in. This was the hardest part-pushing and turning till the threads engaged. If it starts to get real tight, remove the stem, re-lube and try again.


Here is the completed fitting. The stem should NOT be tightened to the collar-but rather a small gap left.


After assembling the hose, be sure to flush it with a solvent (like mineral spirits) and compressed air to clean it out. You don't want the crap from cutting the hose in your hydraulic system.

So, that is it. I hope this will help someone in the future...

Very good right as usual Kenny, I blew a hydro line last week just after the Power beyond lines for my backhoe. And I left my dealer with my a$$ hurting from the price of the replacement hoses. So then I started to ponder the options of making my own. This is a good how to option. Any idea what the crimp style connection jig costs?

Thanks Matt, hydraulic crimpers start at about 1k, plus the specific dies for each size...not really cost effective for the casual user. DHH has some entry level units here: http://www.discounthydraulichose.com/Hydraulic_Hose_Crimpers_s/45.htm

Did the dealer make the hose you needed or order it in? Local shops are usually much less expensive than dealers to get hoses made.

Good post Kenny. We used this type of fitting in various applications at the steel mill with very good results.:good2:

I have had two on my HTL for well over a year now with zero problems. The other intended project is still in the works.

Very good info there. The more I visit this forum, the more I learn. Are those the SAE 100R2AT reusable hose (steel) fittings?
Yes Ron, check the second link I posted. Thanks for the compliments.

You can try g.a. Miller company. they have competitive prices and will lease a crimping machine to you for $1 while you buy parts from them. Not sure how far they go but its worth a shot :) www.gamillercompany.com
