I'm sodering copper tubing and have a street el and regular 90 degree elbows. What should I use?

Use the regular 90s unless you get into a tight spot or need to offset the pipe an inch or less. You could also use street 90s to connect directly into a shower valve or a shutoff as that can reduce the number of joints to solder...

What exactly are you soldering for? Is this a repair or a new install?

Let us know..

A Street Ell has one hub end and none spigot end,(see image). They are used in tight areas and to reduce the number of joints in drainage and to connect tub and shower valve supplies in water pipe. Cheers, Tom
