A hose that holds pressure but lets gas seep through the wall will empty a system over a season and leave the technician guessing. The Cold Line is a fabric reinforced synthetic rubber hose built to SAE J2064, with an eight millimetre bore and a 3.5 mm wall that resists permeation.\u003c\/p\u003e\n\u003cp\u003eThe construction is layered. An inner tube carries the refrigerant, a fabric braid takes the pressure and stops the hose from stretching at the crimp, and an outer jacket handles abrasion against chassis edges and engine bay heat. Inner diameter is 8 mm, outer diameter 15 mm, wall thickness 3.5 mm with a 0.4 mm tolerance, which is the range most R134A service fittings are cut for.\u003c\/p\u003e\n\u003cp\u003eHose is sold by the metre, which is how a workshop actually buys it. Measure the run, add the length the crimp collars consume, and order the number of metres you need.
