    Hi all and thanks for reading,
    I need some help with compression fittings.
    I installed a water filter for my fridge and a faucet on the sink.
    I used 1/4" copper tubing and B&K 1/4" compression fittings from Lowe's. The fittings do not have separate nuts and ferrules. They are one assembly.
    I cannot get these to stop leaking.
    I cut the copper with a good cutter.
    I just snugged the nut and anticipated a slight leak. I figured I would slowly tighten them until they stopped. I've been slowly tightening them with bigger wrenches but they never stopped leaking.
    I wanted to use copper but is polyethylene tubing and quick connect fittings a better option?
    Please help.
    Thanks!

    Those always leak. Use a separate nut and ferrule.

    As I stated the fittings do not have separate nuts and ferrules. They are one assembly.

    I cut everything out.
    I bought separate nuts and ferrules and reused the original fittings.
    Using a cotton swab, I applied a very small amount of pipe dope.
    After hand tightening, I tightened them about 3/4 of a turn more.
    No leaks. I didn't have to touch them.

    This was definitely too much effort for these fittings.

    I posted this on two plumbing forums and several people replied that the nut/ferrule assemblies leak and to get the separate nut and ferrule.

    I sent an email to the manufacturer with pictures. They replied and tried to help. I’m sure they sell a lot of these but I wonder about the design.

    Thanks for the help!
