refrigerant tapping tool question

i have the can taps for r134a and i'm thinking it will tap the r22 and the r12 cans as one of the r22 cans tells me it is compatible with r12. anyway i have to do a recharge on a central system of my house and that is r22 and the only way i can get this r22 is by going the 35 oz size cans. so does anyone happen to know if the r22 tap will fit the r22 inthe 35 oz size? or i have to get the cans with the tpas and they is like 30$ more to get it with the tap over getting it without the tap. thanks
