    Great experience

    4lifetimes had all the products I was after and the prices were all good. I purchased nickel copper tubing, nylon tubing, and a few fittings. Free shipping was a great bonus too. My order was delivered a day earlier than originally scheduled which was a great surprise.

    I made another purchase of the hydraulic flaring kit a couple weeks later and had the same great experience as my first order.

    Very thin walled.

    Would work for brake lines under the hood. I wouldn't use it in areas where it would come in contact with anything that would rub or catch if driving off road.
