Pipes & Hoses
ID vs OD[edit]
Inside Diameter[edit]
Common ID sizes in the US are 1/4" 3/8" 1/2" 3/4"
Inside diameter is very important for barbed connectors
Outside Diameter[edit]
Common OD sizes in the US are stuff stuff and more stuff
Wall Thickness[edit]
Wall thickness is why you will see multiple options for a certain type of hose. Hose with a thicker wall will be stiffer, have a greater bend radius, be less vulnerable to kinking, and support higher pressure.
Material[edit]
Most of the hoses available at the local hardware store are PVC or rubber. YMMV. I haven't researched the affects that glycol can have on either material.
Flexibility[edit]
Hose flexibility is a trade-off. While fairly flexible, thin walled hose can be easy to work with when you are experimenting, it is easily kinked and will rupture at a lower pressure than it's thick walled brethren. Experimenting with flexible hose on a bench may be fairly low risk, but once you nail down the coolant path in your set up, you may want to consider a more durable, stiffer, thick walled hose.
