    What would an offseason be without some sort of new rule? I guess it's good to own a hose company :D

    Basically what the new rule says is all the small -3 oil and brake lines have to have "magnetic steel" fittings, and any junctions have to be steel, in other words, no aluminum fittings.

    "Small pressurized fittings, elbows, nipples, adapters, tees, etc. in the external oil system that have an inside diameter of 0.375 or less must be constructed of magnetic steel."

    The same wording is used for brake lines. Basically that ID is any oil line -6 and smaller.

    I was told by Glen Gray there may be additional rules announced for next season around the time of PRI.

    I can take care of you on the new fittings. We have a pretty robust line of -3 and -4 hose and fittings. If you happen to need new hard lines made, we can do that as well, or sell you the equipment to bend the line. Give JB a call 843.816.6887 or email him at jb@dragracehose.com

    My guess is most everyone! Another well thought out rule change ? I used to think this stuff came from Jim Collins, but not this one.
    I'm kind of new at this, only 50+ years of working with AN stuff, and I've NEVER seen or heard of a steel AN fitting, stainless steel yes, JIC steel fittings yes, but I don't think there is a bulkhead steel nut available ?

    Is this because some dumbass broke one fitting.........vs the known 100,000's of aluminum fittings out there ? Do they have to be heat treated ?

    How about clarification........other than "Magnetic"..........just the fitting ? B-Nut and sleeve ? Passenger car zinc plated dogpoo tube w/ stupid double flare on a tire shaker ?

    Retirement is getting lots easier, not having to deal with stupidity! Thanks for the opportunity to vent (both ends)!

    Years ago, we cracked a brake fitting "T" and used only stainless steel, or whatever steel type the fitting people sold from that point on.

    No more small aluminum fittings

    I was told that there was a lengthy oil down at one of the western swing national events that spurred this. An alky car had a small line off the discharge side of the oil pump to help oil #5 main. The small aluminum fitting coming out of the pump broke and made a big mess.

    stainless is a magnetic metal unless it is 303 or 304 then it is not magnetic..303 is a softer more machinable and 304 is harder

    Only 400 series SS is magnetic. There are about 20 common 300 series types, from soft to "harder than Woodpecker lips", all non-magnetic.

    To the best of my knowledge, all SS fittings are forged from 17PH4, also non-magnetic.

    Bob, I work with 17-4 ph every day. It is definitely magnetic. Don't think they make AN nuts out of it though. You can buy earls pre made #3 and 4 hoses pre assembled with nuts, they are made out of some kind of magnetic steel, not sure what it is.

    new rule

    I believe the intention of the rule is just fittings that can fail while bearing load. The only big failures that Jim talked about were aluminum fittings screwed into rigid parts that had hoses hanging off them. Add some vibration and tire shake and sha-boom. If somebody gets verification of this, please post it.

    Happy Thanksgiving all,

    Marty

    Ken; oops, you are correct. I would just like to have a solid verification on what their meaning really is (as it never seems to trickle down to the local tech inspectors correctly). I have just spent many hours finishing a four wheel hard line F/C in my normal anal fashion. I will consider it extremely dangerous for Joe Average to cut off all his flares on S.S. or any tube to change an aluminum bulkhead nut and sleeve to even Kryptonite nuts and sleeves, then try to re-flair the ends with inferior equipment or knowledge.

    But, alas, I'm old and "invalidated" and hope that severe miscommunication does NOT become another "heat treat" type issue !!!!

    I agree Bob, it is really hard to do a good job on those.

    Just wondering...........I see absolutely NO mention of a small fitting change in T/F - F/C - P/S or anything else down to Jr. Dragster, is this correct, only alky cars ?

    Just a heads up I was told at the NHRA booth today at PRI that this rule is going to be retracting this rule and will be releasing this soon.
