Solenoid Rack
Dear PC,
I found a small leak at the bottom fitting
on my solenoid rack it’s a 90 degree fitting. I was thinking of extending the
line and just going straight in to replace it. But I want to have all the right
fittings on hand before I take it apart.What size thread is it? Would it be ok to extend the line using an in line connector so I can loop it around underneath? Or would it be better just to leave the same set up and replace the 90 degree? I may still have to extend the line a bit.
I know you guys talk about DOT fittings
what are those and where would I get them?Thank you.

Fred, not sure of the specific thread size but I cringe a bit thinking you want to add one more joint that could leak. I would tend to go OEM and try to get a little more length out of the existing hose, but that is me. But if you pay a little more, I could probably come up with a more expensive recommendation.
-
I know I thought about that too more places to leak but this would at least be easy to get too if it did leak. There’s not much slack to this hose but I’ll try to see if I can get it to reach first. Thanks for your input.
-
A picture would help us Fred. I realize adding a section of line to gain more slack is not the preferred method, but I’ve done it using DOT push couplers with no problem, they don’t leak.
-
I know this
may be hard to see but the fitting is at the bottom marked “in” and you can see
the hose is stretched or pinched at the fitting entrance and that’s why I think
its leaking.Where do you get the DOT push couplers?
-
You can get them at some Napa’s, Grainger or a truck parts place.
I couldn’t tell the size, but here’s a 1/4″ at Grainger: DOT

Ok thanks for the help Tom I appreciate it.

Fred put a elbow in Fred with a straight in comp fitting it will be good use thread dope it will
be good don’t worry about it leaking it won’t , just check after install call Grainger they will have it get pipe dope at any auto parts most of them it will be 1/4 or a 1/8 . Grainger has the thread sealant also -
Thanks Peter I’m headed back to Grainger
today I ordered the fittings yesterday. I’ll get some of the pipe sealant too.
I took another look at the hose and if I reroute it there’s enough to connect
it without having to add any more hose. Thank you and everybody for the expertise and advice.Fred

I would just try new hose full length. Most of those in that area are short. Make sure ends are cut square as they tend to leak if not with push fittings. The picture looks like the hose is angled in fitting. That fitting you push the little collar in and just pull hose out. Bob

Thanks Bob yes that angle you noticed is exactly where its leaking.

I just spent a couple of mornings with my head in the steer compartment playing with the air hoses. I did find all hoses were of sufficient length, but some were routed in such a way that they were pulled tight.
In lieu of adding a section of hose it might be worth looking to see if the hose can be re-routed to give you some slack.

The fitting size where it says “IN” is a 1/8″ pipe thread to a 1/4″ hose, in fact, all the fittings on that block are 1/8″ pipe thread.
If you have a Fleetpride in your area, they are a HD Truck supplier, they have them all, compression and Push lock.
-
Thank you all for the insights. It was in fact 1/8 in and I found the fittings at Granger along with the pipe thread compound. I
was able to reroute the hose down and under so that it attaches straight into
the fittings eliminating the two 90 degree angled ones. No leaks at the solenoid
any more!Fred
