What does the "1/2 HP" at the beginning mean?

In the trade, capillary tubes are referred to by the horsepower (HP) of the compressor they match. "1/2 HP capillary" means that this inner diameter is typically used in a circuit running with a 1/2 HP (half horsepower) compressor — it is not the power of the tube itself.

The logic is simple: as the compressor gets larger, the amount of refrigerant that needs to circulate in the circuit increases, so a capillary tube with a larger inner diameter is required. Common equivalents:

• Ø0.80 mm → 1/6 HP  ·  Ø1.00 mm → 1/4 HP  ·  Ø1.20 mm → 1/3 HP  ·  Ø1.30 mm → 1/2 HP
• Ø1.50 mm → 3/4 HP  ·  Ø1.80 mm → 1 HP  ·  Ø2.00 mm → 1.5 HP

⚠️ This is a starting point, not a strict rule. The behavior of a capillary tube is determined by its length as much as by its inner diameter; the refrigerant type (R134a, R600a, R290…) and the operating range (freezer / cooler) also change the result. Even two systems with the same horsepower may require different lengths. For an exact selection, refer to the system manufacturer's table or the circuit calculation; if you are fitting the same tube as the one removed, measure its length exactly as well.
