Question: what is the difference between 1/4 and 3/8 air hose?
Answer: Many people choose 1/4-inch hose because it's lighter than the 3/8-inch variety. It's easier to roll up, carry around and store. Of course, it doesn't hurt that the price tag for 1/4-inch hose is lower than its 3/8-inch counterpart. A wider inside diameter, however, can also have benefits.
