Chester Brzostowski Posted December 13, 2006 Report Posted December 13, 2006 Anybody know anything about these hydraulic fittings. I purchased new brake hoses from Andy B and the hoses are the correct parts but the fittings that the hose screws into are shot. This fitting is called Hose Union part# 40730. Does anybody know if any variant of these can be purchased off the shelf? I assume they can because the hose connectors are new, the hose is dated 11/10/2004. Two numbers listed on the new fittings NS 4404 which seems to be the crimp side of the fitting and 451 stamped on the Hex side. I went to my local industrial pneumatic and hydraulic supplier and he has not seen this type of hose fitting for either gas or fluid. I talked to Andy B. and he only sells the hose with the proper fittings and doesn’t know where to get the in-line tubing to hose connector. The connector has the tubing male on one side and a flat machine thread on the other.??? It seems to me that if the male is available the female should also be available. Anyone have any ideas before I go to the machine shop. Any help would be appreciated. Chet… Quote
Merle Coggins Posted December 14, 2006 Report Posted December 14, 2006 The male end looks to be a SAE 45 degree seat or JIC 37 degree seat in a -3 or -4 size. That should be easy to match up at your hydraulic shop. The other end, however, looks to be some kind of straight thread with a sealing washer of some sort on the end. Does it have an inverted seat like a brake line fitting? I dug out a catalog from a few years ago from a racing equipment supplier here in the Milwaukee area. They have several types of brake fittings, but without being able to positively identify the fitting type it would be difficult to know what would work. Do you have a race shop or raceing equipment supplier in your area? Maybe they could help. They may be able to come up with something, even if they have to make different hoses to fit their fittings. the downside may be that it'll be steel braided lines, which are better but wouldn't look authentic. Good luck, Merle Quote
Chester Brzostowski Posted December 14, 2006 Author Report Posted December 14, 2006 Merle, You are correct on the tubing side.., standard 45’ SAE I believe #4 tubing connector. The hose side is a puzzlement. It is machine thread and goes into a flat. The hose side has a copper compression washer pressed into the fitting. I may just take the fitting to a Tool & die maker to regrind the tubing side surface. I would like to stay original if at all possible. Merle are you a machinist? Quote
Merle Coggins Posted December 14, 2006 Report Posted December 14, 2006 Machinist? No. Just a mechanic that has had a lot of experience with various hydraulic systems and fittings. The info on the racing equipment shop came from a few years ago when I was looking for an upgrade replacement for my motorcycle brake lines. And like most things, I've seemed to keep the catalog. Good luck with your brake lines. Merle Quote
Guest Nile Limbaugh Posted December 14, 2006 Report Posted December 14, 2006 Look for a local outlet of Motion Industries, a nationwide company that handles almost anything in industrial equipment. I'm guessing that what you have is a standard industrial fitting of some sort, there are literally thousands of permutations. If somebody at Motion can't help you I'm sure they will know somebody who can. Quote
De Soto Frank Posted December 14, 2006 Report Posted December 14, 2006 Chet, Suggest you visit the AACA Forum ( www.aaca.org ) and post your question there... You are dealing with a vehicle that has pioneering hydraulic brakes... Don't know too much about the late-20's to early-'30s MoPar systems, but the '24 -'2? used brake tubing that had a single-flare at the end, that went over a cone-shaped male threaded nipple; the tube nut itself was female flare; you still see these fittings on refrigeration systems and some gas connections... At any rate, you might some good advice from some of the pre-Depression MoPar guys over at AACA... Not trying to "diss" the talent-pool here; just observing that MoPars of this vintage are substantially different from the 1935-48 models... Good luck ! Frank McMullen Quote
Taylormade Posted December 14, 2006 Report Posted December 14, 2006 Chet, Still trying to track down that brake fluid remote container. Since these fittings sit out on the frame in a very exposed area, they are prone to rustout. The older design of the brake lines make these things pretty unique. Mine were good, but I tried to find a spare set just in case and never had any luck. A machine shop may be your only recourse. RT Quote
Tim Frank Posted December 14, 2006 Report Posted December 14, 2006 Chet, Is the coupling comprised of one piece or two? Quote
Chester Brzostowski Posted December 14, 2006 Author Report Posted December 14, 2006 Chet, Is the coupling comprised of one piece or two? Tim..,. Yes the fitting is one piece. RT..., The reason mine are so bad is that at some point someone removed them from the tubing and removed the hose fitting leaving the seats to be exposed to the weather. So here lies the dilemma that the seats are pitted. I think a machinist with a surface grinder can regrind the seal seats and I would be able to use them. If not I will have to have them either made up or crossover to a more modern hydraulic line setup. It just doesn't make sense to me that the male hose fitting seems to be available but the female is elusive. Maybe not so hard to understand. Chet... Quote
Tim Frank Posted December 16, 2006 Report Posted December 16, 2006 Chet, I don't think a surface grinder would be the tool of choice...if it was me I would just chuck it in my lathe and take a skin cut at the correct angle.it looks to me as though you could almost "construct" that fitting from a combintion of two gas/plumbing fittings.

Chester Brzostowski Posted December 21, 2006 Author Report Posted December 21, 2006 I know this is off topic but needed to share. I have found a possible solution to the Wagner Lockheed brake hose union used in the 28-29 and 30-U Plymouth. Apparently this type of brake system was used in a number of cars of that period. Some notable models were Duesenberg, Chrysler products up until 1931, Franklyn 28 to 30, Graham early 1935 and 1 ton truck. Kissel Motor Car Company and others like Auburn, Bugatti, Cord, and Mercedes. After a conversation tonight with an 81 year old gentlemen in Pennsylvania who I was referred to by a member of the Classic Car Club of America. The gentlemen I spoke with has been in the auto repair business since 1941 and lead me to classicandexotic.com who actually still sell the parts I am looking for. I need to verify this but this is the best lead I have run across in the past 4 weeks. By the way.., a very long and very interesting conversation. What a wealth of knowledge this 81 year young gentlemen provided. I know this is off topic but I had to share my jubilation with you guys. I am not sure what is more fun.., finding the parts or putting them in and getting the old car back to good running condition. What a rush… from no where man.., to Ya Baby.!!!! We are rocking now….
