Does anyone have any tricks to getting tubing to coil without kinking? I've got some bendable 1/2" OD aluminum tubing that I'd like to use for both my heated puckup and filter wrap but I'm afraid it's going to try'n kink if I bend it that tight. I don't have a tubing bender either. Any thoughts?

Fill the tubing with fine sand or salt to reduce kinking.

Had occasion to bend some aluminum fuel tubing a while back. Dropped by the local Tractor Supply and picked up a 1/2" id tension coil spring, about 18in long. Just bend the ears out of the way and slip it on the aluminum tubing, and bend. The coils keeps the tubing from kinking. It could get a little tight on the spring, but not too tight to preclude sliding the spring off to the next section of tubing to bend.

The sand or salt trick will work ok. If you can cap the ends, water will work too. Personally, I'm using PEX tubing. It's easy to work with and it won't react to your oil. While it will loose stregnth at elevated temperatures, We're only pushing 20 psi max. Been running it for 4 years with zero problems.
