![]() Additionally, there are AN fittings which have straight threads usually with a tapered seat You need to understand that there are "tapered pipe threads" which tighten and seal as they go in. You always have to plumb fuel lines and if you use fuel injection you will need them. Be sure to get one that has the dies to form the push on fuel lines in addition to the angles. The difference in price is often reflected by how complete they are. There are tool kits out there that have hydraulic squeezers for making different flares. Īctually anyone who fools with old vehicles a lot will find that getting the right tools to straighten, bend and flare tubing is a major tool investment. There are also a whole lot more expensive ones out there, but this is a well made tool and I think its fairly priced considering how well its made and how it works. What that means is that you won't split the tube while flaring. You can find some cheaper ones, but this one kind of rolls the 37 degree flare rather than just pushing straight in. I recently purchased a really good 37 degree flare and am really happy with it. A good 37degree flaring tool will cost you more than the cheapo 45 degree tools. Most automotive and AN flares are going to be 37degrees rather than the 45 degrees used on NPT (National Pipe Threads). Īlso you need to familiarize yourself with the angle used by flaring tools. YOU CAN RESELL THEM LATER if you want your money back, but they are much better for tight bends in tight places. They have to be bought in individual sizes. They will get you thru a lot of places, but if you want to make tight bends, you need to watch for ones made like this Rigid bender. Most people buy the cheapo tube benders that bend 3 sizes of tubing. One thing you will find when fooling around with threaded things is that you can do a much better job if you buy the proper tools to work with. Go to this site for their "Thread Identification Guide" and the fitting charts I mentioned. Make no mistake that they are quality components, just not for use on space shuttles etc. The JIC are for industrial use and are quality us they have sizes which are not available in AN specs. An industrial fitting called JIC is also available that is essentially the same as AN fittings but without the same Military Spec rating as the AN fittings. Something I would reccommend to everyone is to go to "Discount Hydraulics" and order a set of their hydraulic fittings charts to hang on your shop wall. Learning about different thread types can be confusing and EXPENSIVE. ![]() Not sure what you need but I would make sure that you have the right thing before you screw it in tight.
