    I just have a few connections to make and don't feel like buying an expensive tool that I might only use a couple times. Is it okay to use hose clamps instead of the crimp connectors?

    Have you considered renting a crimp tool from a tool rental place for a few hours ?
    Costs little and would ensure good connections.
    Pex has a smooth exterior and has little for a hose clamp to grip on.
    I've tried hose clamps on Pex in temporary situations but never found it satisfactory.

    As long as your selling the house, it shouldn't be a problem. I looked at a job once and there were little wet spots all around the house, assuming from all the pex connections. In the basement I did witness some pex connections dripping.

    For just a few connections I would use sharkbites. Or a cheapie tool off of eBay.

    Greeting velvet, I plumbed for years, a couple years go we bought two places in which the old pre-pex , that gray junk, was installed. Doing repairs I used Pex and decided on the Shark bite type of fittings. Even with the gas line. it was scary, now I kinda like it.

    With the Shark bite fittings you don't need the crimping tool. Does that help?

    I think with the insert barbed fittings, hose clamps would be fine, not sure I'd use it inside a wall, maybe if I left it open for a few days to be sure.

    Any place where it's exposed and you can get at it if it leaks it would be OK. Best of luck.

    Also, the "barbed" fittings that insert into the pex and are meant to be used with a proper crimp ring aren't really barbs. If you look at them they are more like ridges and not a barb at all. They work great when you use them as designed.

    Note the cost of the crimp tool is less than 60$ and the fittings you use with it aren't free, still a buck or so each. Then compare to the cost of sharkbites and see that at some point you will break even on the tool investment. I don't think pex will go away.

    It is great for homeowners to have what it takes (skills, tools, and parts) to splice in a chunk of pipe to repair a break, or at least cap that line.

    Thanks. I'm thinking that the doo-dads for hooking up the $365 Nyletherm could double the price. :)

    yes, but the cost of fixing 1 leak will cover the price of the tool.

    Shark Bites on a gas line? I've used them with great results on hot and cold water lines but never on gas.

    Yeah they are not for use on gas and no hose clamps will not work you don"t get even compression all the way around with hose clamps so it will leak.

    Highbeam, I was talking about copper fitting, they are barbs.

    Have you ever installed a Shark bite properly that leaked? For doing small jobs the cost of SB fittings are worth it, for the average guy.

    retired guy, Yep, I purchased it from a propane company, I think the name was Bi State in Nevada. It was one piece from the stub out, 3/4" pipe at the house to the tank where another stub out also 3/4" pipe, when the tank was reached the connection was a Shark Bite like fitting, I was concerned but my test cap show there was no loss of pressure. The tube between as far as I could see was Poly. That was two years ago.

    So was I, they are not barbs. Look again. These are the brass pex fittings and not a hose fitting. Different IDs.

    I love sharkbites, and have never had one leak. They have their place but I will avoid them now that I have the tool IF there is a crimped option.

    I am sure they can make push on fittings that would work for gas sharkbites might even work but they are not approved for that application. And in pa all interior gas lines need to be metallic in order to give more time in case of a fire the only place i have seen plastic used for gas is on exterior grilles. But i have no idea if that code is national or not. And i agree with highbeam they are ridges not barbs.

    I would definitely not use standard SS worm drive hose clamps on PEX.
    Sharkbite are good, crimped are better.
