With this flux core rod, you may join many types of fittings to tanks using traditional aircraft technology. This oxy-acetylene torch process is a proven method and has been used for over 60 years in American aircraft production. These products are the finest in the industry today, and Kent regularly uses them in his shop on expensive aircraft. Our flux-cored products have non-corrosive flux.

comes in 1/2 lb. bundle, 18" long..

Advertised Melting:
Solidus: 1170 °F
Liquidus: 1180 °F
(Kent finds his own results to be: Solidus: 1150 °F Liquidus: 1160 °F)

(Can do 6061 very well - See Reviews)

"Kent:
Just wanted to drop a note and say thanks, I received your flux core rod and absolutely love it. I fixed the 300SL hood with no problems and the customer is ecstatic over the quality of the repair. This car is one of 28 made that is 100% aluminum so I am told and it is nice to see the car getting done correctly unlike the last repairs made. I will definitely be reordering some more of that rod and also wanted to say the meco torch I just bought from you was a big help in this project. It is so nice to have a quality store like yours to go to for stuff like this."

"I got my product today. I quickly got some of the fluxed aluminum brazing rod and applied it to some 3" 6061 aluminum telescope tubing. I am impressed. A mapgas torch and a (very) little skill indicated to me that this is the product I was looking for. Flows right on time, every time. ASTM testing (me and a wild hammer) proves the integrity of the joint as far as I can take it. Thank you."

I repaired the fuel tank vent connection on a Cessna 172 yesterday using some of your flux core silver braze and a Meco Midget torch (both purchased from you). The repair ultimately came out great and I greatly appreciate your instructional videos and the time and effort you put into finding and selling these great products. Quick technical question: the silver braze quickly attached to the 3003 aluminum vent tube, but on the tank it would first hit the tank and bead up without spreading out and sticking. I was very careful to heat a radius of approximately 2 inches around the vent tube and I’d walk the heat in prior to dabbing the braze so I think the aluminum on the tank was hot enough, and it was very clean. Question is there a flux, that I could have put on the tank itself prior to using the flux-core braze to promote faster and easier adhesion to the tank? Again, functionally the repair came out great but there’s probably 2 to 3 times the amount of braze that I would have used if I could have got the brazing rod to quickly and easily spread out and adhere on the tank surface. Any related thoughts, or suggestions on how to improve my technique would be greatly appreciated! You are the best!

Hi Bob,

I am very happy to hear that you got this together. The tank bodies of Cessna, Piper, Beech, etc are nearly always 5052, which is rather difficult to braze - you really have to brush, heat, and flux all at the same time to get the needed bond to happen. Bravo! Perseverance and technique make it happen! Don't worry about the excess filler you have on this first one because as you refine your technique, it becomes a cleaner faster job.

Thank you very much for the feedback, as it is very appreciated.

Kind Regards,

Kent White

Hi Kent,

Thank you so much for the quick response! We were admiring the repair yesterday and it really does look good, especially for my first time brazing an aluminum fuel tank.

Thanks again for all you do for the craftsmen community.
