Hello,

For soldering copper pipe/tubing in the 1/2" to 1" range, what is the
proper size gap between the ID of the fitting and the OD of the
pipe/tubing? For example, the ID of 3/4" type L pipe is 0.785", while
the OD of 3/4" type L tube is 0.750"; would this be an acceptable
solder joint, or is 0.035" too big?

Thanks, Wayne
