Supco Capillary Tube 100 Ft Coil

The Supco capillary tube (also called a refrigerant metering tube or cap tube) is a 100-foot coil of small-bore copper tubing. It is used as a metering device in refrigeration and air conditioning systems. It restricts and controls refrigerant flow between the condenser and the evaporator, which helps the system keep the proper pressure drop and cooling performance.

Key Features:

• Supplied as a 100-foot coil, so you can cut it to the length a repair needs
• Copper tubing construction for durability and good compatibility with common refrigerants
• Fixed-orifice metering design with no moving parts
• Available in different inside diameters to suit different system requirements
• Works for replacement and repair in refrigerators, freezers, window air conditioners, dehumidifiers, and similar equipment

Supco has supplied HVAC/R replacement parts and accessories to service technicians for many years. This capillary tube is a practical stock item for technicians who need to replace a clogged, kinked, or damaged cap tube or to build custom metering assemblies. Choose the variant with the inside diameter that matches your system's requirements.
