Coiled copper capillary tube, 10 ft length, .064 in ID .125 in OD

JB Industries

JB Industries TC-64-10 Cap Tube .064 ID .125 OD 10 ft

SKU CH-TCYA-M3Z6Z

Copper capillary tube with .064 in ID and .125 in OD, supplied in a 10 ft length for refrigeration and air-conditioning systems

  • Precise refrigerant metering with .064 in ID bore
  • Durable copper construction resists corrosion in HVAC systems
  • Exact .125 in OD ensures secure flare connections
  • 10 ft coil length allows custom cuts for installs
  • Ready for refrigeration and air conditioning applications

Capillary Tubing for Refrigeration Systems

This copper capillary tube has a 0.064 inch inside diameter and a 0.125 inch outside diameter. It is supplied in a 10 foot length for use in refrigeration and air conditioning systems. The tubing meters refrigerant flow in capillary-based metering devices. It suits technicians servicing or assembling small-capacity cooling equipment.

Replaces Worn or Incorrect Metering Tubing

This tube replaces damaged, kinked or incorrectly sized capillary tubing that causes poor temperature control. The upgrade is worth it when the original tube is blocked, collapsed or when a system retrofit demands the exact 0.064 ID by 0.125 OD dimensions. It is not for systems requiring a different bore size or for thermal expansion valve installations.

Fits Standard HVAC Assembly Workflows

The 10 foot coil allows cutting to precise lengths during installation or repair. Copper construction permits brazing or flaring connections using standard HVAC tools. The tubing frees the installer from sourcing specific pre-cut lengths. It requires a compatible refrigerant and system design calibrated for this fixed orifice size.

Questions about this item

What inside diameter does the .064 ID cap tube need for a proper fit?

The tube has a 0.064 in inside diameter and a 0.125 in outside diameter, so any fitting must match those exact dimensions.

How do you install the 10 ft copper cap tube without kinking it?

Uncoil the copper tubing gently, make clean square cuts, deburr the ends, and use the correct flare or compression fittings for 0.125 in OD; the step most often missed is deburring before flaring.

When should the .125 OD copper cap tube be replaced in a refrigeration system?

Replace the tubing if you see corrosion, flattening, or refrigerant leaks at the 0.064 in ID bore; copper lasts years but any damage to the 0.125 in OD wall requires a new 10 ft length.
