Have had the best luck with Aeroquip, had the worst luck with Fragola,

 

Using and selling Aeroquip for a long time. They seem well built and consistent. Internal sizing seems larger than the Chinese copies.

 

Contradictory to Boosted, I have all Fragola on my car and not one single problem or leak. Just my experience.

 

All I use is Fragola for the last 10 years, in that time I had 1 fitting leak and they overnighted me a new one, all USA made, family owned...

I have actually had good luck with both the Jegs and Summit branded fittings. Some have been on my car for years and no issues with leaks or breakage. So whoever is making them they are doing a good job.

 

every fitting on my both cars is Fragola and on both my dads cars also,never had 1 issue and they are 100% made in the USA

Makes me wonder what the hell went wrong with the Fragola hose ends I just got, I'm aware they are are family owned and made in the USA, that was the main reason I used them. Both -16 pushlock hose ends the 37 deg taper was off by a mile and leaked like a sive, and 2 of the 4 -12 PTFE hose ends also leaked at the taper. Was able to use conical seals on the -12 and get it to stop, but not thrilled about having to rig it. Hopefully an isolated incident. Lots of my friends use them without issue. I have used lots of their fittings but haven't used their hose ends until recently.

Fragola is all i use for me and my customers. Never an issue, thousands of fittings.

 

Fragola, mainly from the reviews here. No issues but haven't had them on the car that long. Fairly easy to install on stainless line which is a nice bonus.

 

I had started buying Fragola fittings to replace the various different brands on my car. I have 2 different hose ends that seep just slightly. Enough that dust will gather on them and you can see they are wet. They are mated to Fragola adapters so it isn't mixing of brands, although that really shouldn't matter because 37° is 37° but I run a production machine shop so I know how things can go South on your QC if you aren't very diligent. In the future it will be Aeoquip from now on because the fuel lines are next front to back in PTFE. Don't want those to seep for certain.

 

I doubt that there is any manufacturer who makes 100% of their fittings and hose in the USA. Just too much competition in the world market and they must remain competitive to survive. Used to be that Aeroquip, Parker and Weatherhead (now owned by Aeroquip) made their products in the USA and supplied same to US Military, hence the AN fitting (Army Navy) moniker for these parts. Parts made off-shore are not necessarily bad quality as long as the designs and specifications are adhered to and constant inspection is always necessary.

 

Parts made off-shore are not necessarily bad quality as long as the designs and specifications are adhered to and constant inspection is always necessary.

This is the problematic area. All the engineering can be correct. All the specs can be right. All the quality checks can be in place. Once it goes offshore, you lose these manufacturing process controls regardless how much you think you controlled them. Unless you have your internal people on the ground over there making sure it is done right, corners will be cut and quality will suffer. At that point it is break-even to bring in back in house, onshore, to maintain brand quality. They gained nothing but cheaper parts at the expense of cheaper quality.

 

I just hate the idea of Chinese parts on my car, or anything not American made to be honest. It wasn't until after I bought my electric water pump and installed it that I learned Proform is mostly ,if not all, Chinese products. I'm sure there's quite a few things on mine that are not American made that I don't know about but I really try to buy products that are made in America for a few reasons. I guess I'm going to give this Chinese shit that I just ordered a try and see what happens. Don't really care to send it back, order from EBAY and then wait a week before I get it just so I can save $40-$50 when I want to finish something that's been planned to get done for a while now.

If it doesn't cause problems, I may continue to use JEGS and Summit's brand of fittings and hose but I'll definitely start considering Fragola and Aeroquip in the future, even though it is a pretty penny more, but hey, you're probably getting what you pay for with quality and peace of mind.

 

So, I tried and wanted the JEGS fittings to work, but they didn't. VERY tough to get the nipple of the fitting to slide into the ptfe lining, even after lubing both and enlarging the lining with the end of a marker some. I was able to get the nut started onto the threads for the first couple but afterwards was very tough to tighten up with the AN wrench. Could not get the gap between the two, less than a 1/16" (.0625) which is what is needed to seal off. To make sure I wasn't a huge dumbass that forgot how to make the hoses and fittings mate together, I grabbed my Summit Racing ptfe hose and a fitting and had them assembled with ease in less than 2 minutes. In conclusion, the JEGS line of fittings is JUNK. Look closely at the pics and you'll see the difference of how the Summit fitting is tapered, versus the JEGS is straight on the nipple that is on the bottom of the fitting. The olive/ferrule seems to be made of different metal but same design and taper. Sending this shit back tomorrow...

 

This may sound crazy but you have to use whatever hose Jegs sells (all varieties) to work with some of the fittings. I recently (6 months ago)cracked 2 fittings #14 or 16 putting hoses together. I was using russell hoses I believe on a friends car. Got the Jegs hoses and went right together. I've made alot of lines and never did that. I've had good luck with mine but have seen alot of people have problems. Especially #6 fittings. They will take them back and they know they are problematic.

I'd prefer to use Speedflow or Aeroquip over any mentioned above.

 

Speedflow or nothing.

 

I've used Aeroquip for almost 30 years. Out of thousands, I've never, ever received a bad fitting or had a leaker. Their flow rates are the best as well. Hard to beat 100% success.
Their anodizing colors aren't as pretty or bright as some of the others, but they remain damn good fittings.

 

I ended up buying some Fragola and made the lines with them today. I liked the hose, the fittings are so-so. The an to npt adapters I got don't look all that great. The pipe thread side seems to not be a very clean cut from the machine and threads are iffy. The hose ends are a bit tougher to make work but overall not bad, even though 1 out of the 4 I bought ended up being junk. Luckily I had a spare Summit hose end in my inventory, so I used that in it's place(hopefully that won't come back to bite me in the ass), and again it was easier to mess with than any other brand I've dealt with so far. I might venture out to trying Aeroquip one day, should I ever have to remake some lines. The reason I chose Fragola this time was to see how they were and because their hose was quite a bit cheaper than Summit's, even though so far they are my favorite.

 

100% fragola here. All PTFE front to rear. No issues with any of the fragola products I have used. I have crossed threaded a nut a couple of times trying to get it started, but thats on me, not the manufacturer.

 

My brother works for an Indy car engine builder and one of his coworkers were talking about hose fittings. They both agreed that Aeroquip was the best. I have personally used Aeroquip for more than 30 years without a problem. I know that Aeroquip still has a factory in Jackson Michigan but I don't know how much of their product is made in the USA.

No shit? That's cool!

I'm surprised no one has mentioned XRP yet. From their catalog, "Manufactured in our own facility in the U.S.A., every XRP Performance Hose End is race-ready when it reaches our customers." Their XR-31 hose is also specifically called out in their catalog as made in USA, and this is what they have to say overall: "The lion’s share of XRP’s products are engineered and manufactured in the U.S.A. XRP has been instrumental in industry efforts to accurately label true 'Made in U.S.A.' products because we think our customers deserve to know!"

100% Chinese

 

I've never had bad luck with Russel. I just got all Fragola stuff from motion raceworks with a trans cooler kit and 2 of the 4 fittings leaked at the swivel. sent them back and now one of the 2 leaks. they shipped another for free. now its fixed. a lot of fucking around to put a trans cooler on.

 

Brown & Miller or XRP........in that order.
The best period!
