The BPC1438 is a pair coil of insulated copper tubing, sized 1/4" x 3/8" and supplied in a 20-metre length, designed for R410A and R32 refrigerant systems. Built with triple-layer insulation and annealed copper construction, it meets AS/NZS 1571 standards and performs reliably in climates from -40°C to 105°C. The BPC1438 is the choice of licensed air conditioning technicians for efficient, durable refrigerant line runs.
Air conditioning installation requires careful attention to refrigerant line insulation: uninsulated or poorly insulated copper tubing allows heat loss in the liquid line and condensation in the gas line. The BPC1438 addresses this with triple-layer insulation that combines UV-resistant outer protection, intermediate polyethylene foam, and a closed-cell cross-linked PE inner layer. This three-stage insulation system maintains refrigerant temperature over long runs, reduces condensation risk, and stands up to UV exposure without cracking. Most installations from split-system retrofits to new commercial builds use properly insulated pair coil to keep system efficiency high and callbacks low.
Licensed technicians specify the BPC1438 because the annealed copper tube bends and flairs smoothly without hardening, making on-site fitting straightforward and reducing waste. The tight polyethylene sheathing stays bonded during installation and resists moisture entry. Meets EN 13501-1:2007 fire compliance (classification D-s3-d0), so it passes building code inspection on commercial and residential work without modification. Stock rotation is simple since the BPC1438 pairs seamlessly with all standard 1/4" x 3/8" quick couplers and fittings.
The BPC1438 is not suitable for outdoor-installed condensing units (where uninsulated lines are sometimes acceptable per engineering design) or for systems running at pressures or temperatures outside the specified -40°C to 105°C range. It is not designed for direct burial in concrete or for prolonged direct UV exposure without protective conduit.
Verified Sparky Direct customer reviews: AC Pair Coil 1/4 x 3/8 Heavy Duty Insulated Copper 410a / R32 20m (BPC1438)
"Very good AC pipe. The insulation is probably the best I've had." — Andrew
"Good value. Convenient." — Shortman
"Fast delivery, competitive pricing." — Nate.P
(BPC1438)
The BPC1438 is designed for R410A and R32 refrigerants used in modern split-system air conditioners and heat pumps. It is not rated for older R22 systems or other refrigerant types.
Installation of the BPC1438 must be performed by a licensed air conditioning technician. Refrigerant system work requires proper evacuation, pressure testing, and charge procedures that are regulated under Australian standards and electrical licensing law.
Yes. The outer layer is UV-resistant and rated against cracking and degradation from direct sunlight. However, where the BPC1438 runs exposed on external walls for extended periods, protective conduit or shading is recommended to extend service life.
The triple-layer insulation system minimises condensation on the gas line and maintains refrigerant temperature efficiently in tropical and subtropical climates. The -40°C to 105°C operating range covers hot Australian conditions without thermal failure or insulation degradation.
Annealed copper is soft copper that bends and flares smoothly without cracking. Unlike hard-drawn tubing, the BPC1438 allows technicians to make on-site bends and flare connections using standard tools, reducing installation time and waste.
Yes. The BPC1438 meets AS/NZS 1571 standards for annealed copper tube and carries fire classification D-s3-d0 under EN 13501-1:2007, satisfying compliance requirements for commercial and residential installations without special containment.
The BPC1438 weighs 7.8 kg per 20-metre roll. A single technician can carry and position the roll on site, though a second person is recommended for managing full-length runs during installation, especially on ladders or in confined spaces.
The Generic BPC1438 is available online from Sparky Direct, with Australia-wide delivery to any state or territory including regional areas. Sparky Direct is an Australian electrical wholesaler established in 2005, supplying more than 500,000 customers with transparent trade pricing.
