What is Hard temper tube (lengths) What is soft temper tube (roll/coil) |
Hard temper tube is generally recommended for exposed lines, such as hot and cold water supplies to fixtures or any lines suspended on hangers. The rigidity of the hard temper tube resists sagging and deflection stresses between supports

Soft temper tube can be manipulated through small holes and is ideal for remodelling and repair work of piping system |
