Pecks plumbing fittings

[Tim Mahoney]

Do you know where I can buy pecks to the old gray water supply lines used in mobile homes. I understand they are called transition fittings. I need 3/8, 1/2, and 3/4" sizes for my maintenance business. They are not available at my local plumbing supply houses. Help...

Half inch Poly-Butalyn to half inch Pex?Just use a stepped tee and clamp both ends with a half inch compression band.Worked for me numerous times.If you plumb a lot you probably have compresion tools of popular sizes,you can't do much without em these days.
