    Is there a saddle valve(for refrigeration) that can grab a
    line thats 1/2" or larger?(I could use it upstream of a hold back valve on a freezer)

    theres one that you solder on then stick the schrader valve on using a brass cap..
    Let's give nukes a chance.

    I believe that bullet tap-a-line valves come in 1/2", but I hate using them, they often leak after a little while. I only use them on small fractional stuff that will be tossed in a year or two.

    Scroll down to the SF5000 series (page 8-4).

    You want an SF5512 for 1/2" OD.

    Turn off the unit.
    Braze on the saddle.
    Insert the o-ring and self-piercing core.
    Tighten the cap (this will pierce the line and lock the core in place).

    Remove the cap, and the core stays in place.

    You could use a Bullet Piercing Valve (BPV12) instead, but they tend to leak.

    I've never had a problem with the SF5000 series.

    Robinair used to make one up to 3/4"OD. Rubber gasket, though...

    Legal, but poor practice.

    Okey I bought it today.It`s A2, for 1/2 to 5/8 inch pipe.And I think the O ring it uses is better than the one that uses gasket.Thanks for all info.
