When are cheap Ebay AN fittings acceptable?
 

Now, i would never run fluids under pressure through them (oil, fuel), but what about valve cover vents? I need -10 hose ends for my venting setup, and going with Ebay crap saves me $60. Yes, i'm a cheapass. Yes, i'm willing to not save the $60 if it saves my car from spontaneously exploding.

My reason for considering this is that these lines are going to a vented can anyways, and there should be very little to no pressure through these lines.


So... would the car go up in a huge explosion if i were to use ebay hose ends in this application?

When they look this good and are this cheap:

I've never seen fittings cheaper than the Mocals through Bat Inc.

Those are same price or more than Summit. I'm talking about REALLY cheaping out and getting the "same" stuff from Ebay for 50% less, but wondering if that's a bad idea (definitely wouldn't for fuel or oil) even in this particular application.

It's a catch can, who cares? They'll probably be a bitch to assemble, but it's just a catch can.

Breather lines....that's all I am going to say, just breather lines.

That's what my thought process was, just figured i'd get some affirmation from a larger potentially more knowledgeable base since one of my local buddies seems to think my car is going to explode if i do this. Appreciate it.



Ohhhhh... is THAT what they are?

That would be my assumption.

I don't feel like looking, but how cheap is cheap?

$9 shipped for a 90 degree -10AN hose end, $8 shipped for a straight -10AN hose end. I need 4 of each. It adds up.

What? Which type of hose end are you looking for? This Style?

Nice find.... yes, that style.



[edit]

Ehhhhh nevermind. Still ~$30 more with the 90s and shipping. Bummer.

Yeah, I use plumbing monkey for all my fittings. They arent as fast as summit if you needed a part yesterday. But you cant be the prices on legitimate name brand parts. They actually affiliated with a real industrial fitting distributor, so if you want to order like 100 of the same fitting, or a couple hundred feet of hose, their industrial partner might be able to get you a better deal.

They're $96.34 shipped for the 8 fittings i need vs. Ebay from Speed_Daddy for $67.16 shipped.

Now the catch is that the PlumbingMonkey stuff is actually legit parts. :rofl:

Very cool, though... i may just order all my -6 through them to make up the difference at the same time, actually.

Oh, and forgot i need two -10 female caps.

Thanks for the site link!


When you say they aren't as fast as summit (I get stuff next morning from Summit), just how much slower are they? I'm cool with 5-7 days, but i can't have this drag on.

Yeah, we're talking the cheap shipping takes a week or so. I've bought from there on a couple occasions and it take then a day or two to get the stuff packaged in the box, and on the truck.

Cool, that might be alright. I must admit i haven't checked Earl's yet. They have a shop about 15 minutes away from me. In the past, i've found their prices to be good sometimes, and awful sometimes, but there's no wait or shipping charges. (But there is tax.)

I like ANplumbing.com .. they have pretty great customer service, and are pretty cheap too. But if you're on a budget for "just breather lines", why not use push lock instead of braided? It's way cheaper, and works pretty great. If it's good enough for my heater core lines, it should be plenty for your breather.

I think the choice of braided is more for looks. Fuel hose would be more than acceptable, hell 20 cents a foot clear vinyl tubing would work with barb fittings from mcmaster. But both look like shit.

Well, and neither of those really seal that well when just jammed over some -10AN male fittings previously welded into my valve covers.


It's BECAUSE RACE CAR at this point whether i like it or not.

As long as its the right size... :fael:

Push lock hose has an AN fitting on one end and the proper hose size and barb size to make an exceptional seal on the other.

I built race cars professionally... we used reinforced tygon hose on vent lines. Three reasons, it's lighter (light = good), it's cheaper (cheap = good), and you can see when stuff is venting or not with it. Sealed just fine with a good quality hose clamp.

Yep, will probably do this on the other cars, but i already paid good money to have these valve covers welded, so they're staying. :rofl:

Yes, the transmission is hideous. Oh well. :giggle:

these may be of use to you then: Fragola -10an 90 Degree Push-Lite Race Hose End

(ignore seller, I was just searching for -10an nipple fitting)

Nice build, but I've got to ask.. Why an fittings as breathers to the catch can and brass fittings with regular fuel line on your fuel rails?

Check out AN Fittings Direct, they are the same company that does siliconeintakes.com. I have been reasonably happy with the fittings from them in the past. Now I only use Aeroquip though, but that is because I can buy them locally. Honestly if you already paid to have the VC welded, stop being extremely cheap on the fittings. I have used cheap fittings in the past and they have always been a bigger pita then the money I saved has been worth.

Cool, will keep those in mind for later builds, but i've already got the line for this. :)

Fuel setup isn't done. That's just what came on the ITB setup.

Cool, thanks! I've spent much time on their site wondering about whether they're worth it, but never talked to anyone that had actually used them. :)

Maybe it's time to just buy the Ebay fittings and be the crash test dummy. If something blows up I'll help you fix it.

Well i fully plan on blowing up this first motor in an effort to see how far stock internals and oiling will tolerate being revved. Thinking about starting an over/under pool. I think i can see 9500rpms a few times before shit goes totally bad.

Better? :)

Well the fail has arrived. I'll be sure to document my absolutely terrible experiences with them that will eventually push me to consider suicide.

https://www.miataturbo.net/attachmen...ine=1354633357

Did I mention I used 1 ebay fitting (I had it kicking around) for my oil drain feed? Another zero pressure line...

it slowly seeps oil out...not a huge leak, just a drip every now and then, just enough to piss me off.

Well, if i get a lot of fluid through these lines, it's because my motor is toast, so....

BRB suiciding.




Ok, actually... these were pretty painless. No, they didn't FEEL as good as the XRP/Earl's/Aeroquip stuff i used everywhere else, but they assembled easily, fit fine, and the threads were fine.

Would i use them for liquids? Nah. Are they going to be just fine for this? Yep.

Who made your catch can?

Dude named Wade in Louisville. He welded the bungs into the valve covers as well.

How much did he charge to make the catch can?

I am planning on building me one similar to that in the spring. So I might be asking you for some more pictures of it in the springtime.

I think $130 for it. Internally baffled. 4 inlets, 2 drainbacks, forgot the size for the vents, but i might have the part numbers for the filters i ordered around here somewhere.

He might have another available if you're interested. He typically makes these for Hondas, they fit nicely where the batteries used to go.
