Spartan quoted me $1,900 for the block. So I am asking if anyone knows whether the push-fittings can be removed from the block and replaced or are they integral to the block and not replaceable? The tech at Spartan did not know and I don't want to start trying to remove them unless I know they are replaceable.
Anyone have any experience? Oh yeah its a Parker manifold and so far they have not responded to my inquiries.
I've done a bit of research on "Push to connect" fittings and, one thing I've found so far is, while they are widely used in the RV and trucking industry, if you go looking for them at local RV and many auto parts stores, they most of the time give you that crooked puppy head look. Most don't have a clue what you're asking about.
So, I went onto ebay and Amazon and, based on just what you type in, you'll find just about any of those push-to-connect type fittings. Now, not seeing your manifold and, all the fittings attached to it, it's hard to say what can and, what cannot be replaced. But, off the top of my head, I'd say most can. What you need to know is, what size threads you're dealing with and, what sized tubing is involved.
Also, if there's any angles, flares, female and or male pipe threads etc. It's not all that hard. Once you learn what you've got, you just pop onto ebay and or, Amazon to see what you can find.
The first thing I'd do if you already haven't is, get a spray bottle of soap and water and, build your air system to max and, spray all those suspected fittings/lines/connections and more. Check to see where EXACTLY all the bubbles might be coming from. It could be the tapered male/female threads and not the actual push-to-connect fitting. That might be a real simple fix. Bleed the air system down to nothing, remove any suspect fittings from the manifold and, clean well, then, tape them all with good Teflon tape and, re-install.
Oh, by the way, if you don't know how to operate a Push-to-connect fitting, just ask. They can be a bit tricky.
Then, build the air system back up to max and check results of your work. Not very hard other than access to some of those fittings. Good luck.
