    I have two wirsbo 1/2" pex lines I need to have expanded to fit a 3/4" copper adapter. Local plumber wants $150 and I hate to buy a $200 tool for two fittings. Any other options?

    could you use a pex to 1/2 inch MIP and then a 3/4 copper to 1/2 inch FIP and thread them together.

    Have you checked to see if you could rent the tool?

    Is there a Shark Bite fitting(s) that you could use?

    I like the tool rental idea. I forgot to mention it's for hydronic heating application using HePex (oxygen barrier). Not sure if sharkbite fittings would be suitable for this application.

    Not sure I'd expand 1/2" to fit 3/4.
    There are plenty of 1/2 to 3/4 adapters out there.

    One local HW store will let you use the tool free if you buy the fittings from them. Check around. I've heated a tapered drift pin in a pinch, slid the pex on the fitting, and applied a small hose clamp. Against all the rules I know but hasn't failed in 3 years.

    You can buy a pex tool that crimps all 3 sizes 3/8-1/2-3/4 and uses a vise grip pliers at Home depot for about $35 if your interested.
