Tell me why I shouldn't use this hydraulic hose

9.99 for 4 foot of high pressure hose with 3/8" npt ends. Seems a cheap route for hydro assist or full hydro. Spin on the correct adaptors (assuming they make them) and put them on.

Looks like I will be doing assist instead of full hydro. My application would require two 4' lengths of hose with 90* swivel ends all around. The cylinder is #6 male 37* JIC and the box tapped to 3/8" tappered npt.

20.00 2 hoses
28.00 for 4 swivel ends
12.00 for 2 adaptors
--------
~60.00

Hmmm. That may be approaching the cost of custom lines built.

PSC 8' hose and nice reusable end kit sells for $69. I guess that may be the best bet and quickest/easiest solution and I'd have reusable ends.
What do you guys think?

All that matters is the pressure rating of the hose compared to the output of the pump.

 

[tlspeed]

cuz its cheaper at discount hydraulic hose if you want standard ends. If you want reusable then go with PSC

8'- 3/8" hyrdo hose
4- 90 degree JIC swivel
2- 3/8" npt to 3/8" JIC

$42.40 shipped to Mephis, TN.

Can't see the jpeg (non member) but thats a good reason- You da man!

just remember correct for in hydraulic hosing is you never use 2 90 hose ends on the same hose. if you need too, use one 90 and the other a straight hose end with a 90 fitting.

because 2 90 hose ends for all intents and purposes can never be clocked perfectly s there will always be tortional stress on the hose braids after its installed. now pressure cycles through the hose will fail it long before its serviceable life span with ANY twist tension even if you can't see it.

1 striaght hose end on either end of the hose will totally eliminate that possibility.

just fyi. and I know I've seen lots of guys do it. just know its not right.

Very true, looks like switching to a 90 degree adapter fitting on the steering box or cylinder would be best.

Thanks Demon and TLSpeed.
Hmm, that confuses the matter some.

So using the ends in this kit-
http://www.pscmotorsports.com/hk2022-8-steering-cylinder-hose-kit-a-p-270.html
is a bad thing?

You would opt for something like this
http://www.pscmotorsports.com/hk202...b-p-271.html?zenid=9p6nelurrhkjp6ob4c2h8ki2j0
with the straight (verticle swivel ) ends at the ram with something like this
http://www.discounthydraulichose.com/90_Elbow_Swivel_Joints_s/104.htm
to give it the 90* (and horizontal swivel)?

I think when I order I'll have to call them and have them help me build these correctly. Describing wtf I'm doing so they get a clear pic of what I'm talking about and what my needs are can be hard.

What hose would I choose? I know PSC hose rating is 2500psi.
Should I stay away from the reusable fittings?

Thanks

 

[kennyw]

Nothing wrong with reusable fittings... but be sure you get fittings and hose from the same manufacturer. DON'T mix Weatherhead with Parker or anything like that.

 

[Mudstud]

Gotcha.

3/8" Hose x 3/8" ORFS Female 90°

What does OFS or ORFS stand for?

ORB stands for what?

 

[tlspeed]

Its not a bad thing, just not great because with 2- 90s crimped on the hose doesnt get to flex when your are installing it. Which means that unless the fittings are in the perfect orientation, you will have to twist the hose itself to install. With one end being straight the 90 can be orientated in any position and the hose is will be unstressed. Since the hoses are unstressed the will lay nice and will not be twisted.

Personally, I would go 90s on one end and straight on the other with 90 degree adapters in the steering box.

As far as the resuable ends, I beieve they are more desirable if you can afford them. You can fix them on the trail, if you need to. I just carry a spare hose with me, instead. Anything else, let me know

 

[Mudstud]

So if I order the hose with crimped ends I would need:

2 of these for the box which is tapped with 3/8 18 tappered npt

MPX90-06-06 | 3/8" Hose x 3/8" NPTF Male Pipe Swivel 90°
$7.07 What is the F for in NPTF?

And then order 2 of these for the ram which is #6 male 37* JIC
FJX90-06-06
FJX90-06-06 | 3/8" Hose x 3/8" JIC 37° Female 90°
$5.24

OR am I missing a swivel in the othere direction to relieve twist of the hose?

 

[Mudstud]

OK I get what you are saying- the set up above will not work becuse there is nothing allowing it to twist the way it needs to liniearily. Be right back.

Seems the PSC kit would work then cuz if you put one fitting on the rig and then curve the hose toward the other port and let that dictate the direction the other fitting would need to be assembled- that would take the twist factor out.

 

[kennyw]

NPTF = Dryseal threads. They are sealed by pressure and interference and do not require a thread sealant.

 

[Mudstud]

Thanks.

Seems this would be ideal 1= JIC and 2= nptf swivle but sizes begin at 1/2"

Looks like this is the ticket- 3/8 18 nptf to 3/8 JIC male adaptors out of the steering box and then one of these into a straight swivel hose end.

I see a mixture of steel and brass fittings. I'd want steel right?

What does BULKHEAD mean in reference to an adaptor?

 

[dremu]

What does BULKHEAD mean in reference to an adaptor?

Generally means it has threads and a nut in the middle, i.e. to mount into a hole in a panel, with the ends on each side of the panel.

You'd use something like this, say, at the firewall, rather than drilling a hole through and just pushing the hose through =))

-- A

 

[tlspeed]

looks like number option 2 would be the ticket. You could also go with 90 male pipe to male JIC adapters. You would just have to thread them into your steering box at the right position.
like tis here http://www.discounthydraulichose.com/product_p/2501.htm

Yes you want steel fittings, not brass.

As far as bulkhead I am not sure, i know one meaning refers to a fitting to pass through a panel or

 

[Mudstud]

Ok I have this figured out.

Using this hose (is 212* OK?)

R2-06 | 3/8" SAE 100R2AT Hydraulic Hose (by the foot)

I'll get these for outta the steering box.

Which will screw into this.

Which will screw into this swivel crimped hose end
http://www.discounthydraulichose.com/ProductDetails.asp?ProductCode=FJX&CartID=0

And then this crimped swivel end at the ram.

If you say this should work I'm gonna order it then but I guess I need to get more specific measurements tonight. Don't wanna guess.

 

[tlspeed]

Yes this will work fine in my opinion.

As far as specific measurements, I am not sure on what discount hydraulic will do as far as making hoses complete hoses. but most auto parts store should have a crimper.
