About this item
Few sellers list the inside diameter, but this one does. This 5/16 inch OD copper tubing has a 0.257 inch ID and comes in a 50-foot length for HVAC and refrigeration jobs.
Why does the 0.257 inch ID matter on 5/16 copper tubing?
The OD and ID figures work out to a wall of about 0.028 inch. That helps you check whether the tube suits your flare tools, fittings and pressure needs.
- Uses: 5/16 inch shows up on smaller refrigeration equipment, ice machines and some older systems.
- Joining: make sure your flare block or fittings have a 5/16 slot.
- Unknowns: temper and coil form are not stated, so look at the photos.
- Length: 50 feet covers repairs with tube to spare.
