Refrigeration Copper Pipe Components

Core specification parameters:

Pipe diameter range: Nominal diameter (DN): Commonly found in water systems (such as DN15, DN20).

Outer diameter (OD) of refrigeration copper tube:

Household air conditioning : Φ 6.35mm (1/4 “), Φ 9.52mm (3/8”), Φ 12.7mm (1/2 “).

Commercial air conditioning : Φ 15.88mm (5/8 “), Φ 19.05mm (3/4”), Φ 22.22mm (7/8 “).

Wall thickness:

Lightweight (K/L): 0.8mm~1.2mm (R22/R410A).

Heavy duty (M): 1.5mm~2.0mm (high voltage R32 or commercial machine).
