What is the term for joining tubing without flame using a powered crimping tool?

Explanation:
Crimping. This is a mechanical method where a powered crimping tool deforms a ferrule or the tubing itself to create a tight seal, without any heat or flame involved. Because no melting or filler metal is used, the joint is formed purely by compression and the material’s deformation under pressure. Brazing, welding, and soldering all rely on heat (and often filler metal) to join metal parts, so they don’t fit the “no flame” condition. Crimping is the quickest way to make a leak-tight tubing connection when heat is not desired.
