Copper Tubing

Flytech supplies copper tubing for instrument air, refrigeration and general pneumatic service. Copper bends easily by hand or with a former, holds its shape once formed, and takes compression fittings without special preparation, which makes it the practical choice for panel work and short runs where a technician needs to form the line on site.

Soft annealed copper is supplied in coils and is the grade used where the tube will be bent and routed. Hard drawn copper comes in straight lengths and is stiffer, suited to fixed runs where a rigid line looks and performs better. Copper also conducts heat well, which is why it remains standard for refrigeration and heat transfer lines rather than stainless.

Key Features
• Soft annealed in coils for site bending, or hard drawn in straight lengths for fixed runs
• Forms easily by hand or with a bending former, and holds the shape once bent
• Takes standard compression tube fittings without special preparation
• High thermal conductivity, which is why it stays standard for refrigeration and heat transfer
• Common standards include ASTM B68, B75 and B280 for air conditioning and refrigeration service

Frequently Asked Questions
Can copper tubing be used for ammonia refrigeration?
No. Ammonia attacks copper and its alloys, so ammonia systems use steel or stainless steel tube. Copper is suitable for the common fluorocarbon refrigerants but should never be specified for ammonia service.

What is the difference between soft annealed and hard drawn copper tube?
Soft annealed tube is supplied in coils and bends readily by hand, which suits site routing and panel work. Hard drawn tube comes in straight lengths, is stiffer, and suits fixed runs where a rigid line is preferred. Hard drawn tube should be annealed before tight bending.

Does copper tubing work with compression fittings?
Yes. Copper is soft enough for the ferrule to bite and seal properly, which is one reason it remains common in instrument and pneumatic work. Use a tube insert on thin wall sizes where the fitting manufacturer recommends one.
