Capillary Tube with 1/4″ SAE Flare Nut for refrigerators and refrigeration systems,TP2 copper, OD 0.5-6.35mm, lengths 1m/1.5m/2m. Nut size 1/4″ SAE or custom. Used as throttling device and connection line. Compatible with R134a, R600a, R22.
Our Copper Capillary Tube with Brass Nut is a complete throttling and connection assembly for refrigerators, freezers, and small refrigeration systems. The capillary tube controls refrigerant flow and pressure drop, while the brass flare nut at one or both ends allows quick, leak-free connection to filter driers, compressors, or evaporators without additional fittings.
Made from high-purity TP2 copper tube and forged brass nuts, it offers excellent corrosion resistance and reliable performance. Available in standard lengths and customizable nut sizes.
