QsanTec Dualcoil 1/4" x 5/8" – 20 m, Double insulated copper pipe for heat pumps (R32/R410A)

QsanTec Dualcoil is a high‑quality, factory‑insulated dual copper tube set designed for air‑to‑air and air‑to‑water heat pumps, air conditioning systems, R32 and R410A refrigerants, and professional HVAC installations. The set includes 1/4" (6.35 mm) and 5/8" (15.88 mm) soft copper tubes with durable, flexible PE foam insulation that ensures high mechanical strength, minimal heat loss and long service life. The copper tubes are made from 99.90% Cu annealed copper and comply with EN12735‑1 and JIS H 3300 C1220T standards. The insulation meets EN13501‑1 fire safety requirements (B‑s3,d2 or BLs1d0 depending on market).

Key advantages: factory‑insulated dual tube set for faster and cleaner installation; high‑quality soft copper with 99.90% purity; chemically cross‑linked PE insulation with 30x foam density; low thermal conductivity of 0.043 W/m·K; EN13501‑1 fire classification; wide temperature range from –40 °C to +120 °C; very low water absorption of 0.01 g per 100 cm²; vapour permeability of 10 ng/m²·s·Pa; supplied in rolls with metre marking for precise measurement; suitable for R32 and R410A refrigerants.

Technical information for copper tubes: the 1/4" tube has an outer diameter of 6.35 mm, wall thickness 0.8 mm, copper purity ≥ 99.90%, phosphorus content 0.015–0.040%, tensile strength 205 N/mm², elongation ≥ 40%, compliant with EN12735‑1 and JIS H 3300 C1220T. The 5/8" tube has an outer diameter of 15.88 mm, wall thickness 1.0 mm, copper purity ≥ 99.90%, phosphorus content 0.015–0.040%, tensile strength 205 N/mm², elongation ≥ 40%, compliant with EN12735‑1 and JIS H 3300 C1220T.
