        Sparky Direct | AC Pair Coil 1/4 x 5/8 Heavy Duty Insulated Copper | R32/410A 20m

        The BPC1458 AC Pair Coil is a pre-insulated twin refrigerant line set rated for R32 and R410A refrigerants, sized 1/4" liquid x 5/8" suction and supplied in a 20-metre length. The BPC1458 is engineered for split-system air conditioning installations where efficient refrigerant transfer, high-performance insulation, and compliance with Australian standards are essential.

        Air conditioning installers work with pair coil on residential and light commercial jobs where pre-insulated tubing cuts installation time and reduces site handling. The BPC1458 arrives as a bonded twin-line set, eliminating the need to source and lag individual copper pipes separately. Heavy-duty insulation provides protection across hot and cold climates, and the triple-layer foam jacket handles the full temperature range from minus 40 to plus 105 degrees Celsius without degradation.

        Professional HVAC installers favour the BPC1458 for fast setup on split-system runs. The pre-bonded pair means both liquid and suction lines fit together, so flaring and brazing stay straightforward, and the product bends smoothly without insulation damage. Annealed copper construction meets AS/NZS 1571 standards and carries an EN 13501-1:2007 fire rating, making it a compliant choice for domestic and light commercial work. Competitive pricing combined with proven quality keeps this size popular across residential retrofit and new-build projects.

        Features

        • Pre-insulated pair coil — Liquid and suction lines bonded together in one 20-metre roll, ready to flare and connect.
        • 1/4" x 5/8" sizing — Matches common mid-size residential and light commercial split-system specifications for R32 and R410A.
        • Triple-layer insulation — Outer embossed UV-resistant layer, middle polyethylene foam, and inner closed-cell PE layer for superior thermal protection.
        • Wide temperature range — Insulation rated -40°C to +105°C, suitable for hot and cold climates without compression or degradation.
        • Annealed copper tubing — Meets AS/NZS 1571 standards for Australian split-system applications.
        • Dew point proofing — Extruded copper construction eliminates condensation formation on the line run.
        • UV-resistant finish — Embossed outer layer prevents cracking, water ingress, and age-related deterioration over time.
        • Fire-rated insulation — Complies with EN 13501-1:2007 classification D-s3-d0 for safety standards compliance.
        • Smooth bending — Flexible design allows field bending without kinking or insulation splitting during installation.
        • Weight manageable — 12.5 kg total weight per roll, practical for single-handler transport on site.
        • Installation by licensed technician only — Flaring, brazing, and connection to split-system units must be performed by a licensed air conditioning installer or refrigeration technician.

        Where to use

        • Residential split-system retrofits — Replacement of damaged or corroded refrigerant lines between indoor and outdoor units on domestic air conditioners.
        • New residential air conditioning installations — Pre-insulated pair coil reduces on-site labour and material coordination for new-build homes and renovations.
        • Light commercial split systems — Office, retail, and small commercial spaces where R32 or R410A systems serve single or multi-zone comfort needs.
        • High-ambient installations — Insulation performance up to +105°C handles installations in hot climates, roof spaces, and outdoor wall runs.
        • Cold-climate applications — Temperature range down to -40°C supports installations in alpine, rural, and cooled storage environments.
        • Post-warranty service upgrades — High-performance pair coil for field replacement when original equipment has reached end-of-service.

        The BPC1458 is not suitable for drain lines, power cables, data wiring, or any application outside refrigerant transfer between split-system units. Do not use this product for commercial industrial refrigeration, where large-scale or ultra-high-pressure systems require engineering-grade specifications. Connection work must be performed by a licensed air conditioning technician in compliance with all local electrical and refrigeration codes.

        Verified Sparky Direct customer reviews: AC Pair Coil 1/4 x 5/8 Heavy Duty Insulated Copper 410a / R32 20m (BPC1458)

        "Perfect. Bends good. Received the black insulated coil. Would definitely buy again. Good price too." — BG

        "Cheap, great quality" — Drew

        (BPC1458)

        The BPC1458 is rated for R32 and R410A refrigerants used in modern split-system air conditioners. It is not suitable for older R22 systems or other refrigerant types. Always confirm refrigerant compatibility with the split-system manufacturer's installation manual before purchase.

        Flaring, brazing, and connection of the BPC1458 to split-system units must be performed by a licensed air conditioning installer or refrigeration technician. Installation by unlicensed personnel may void warranties and breach building codes in most Australian states.

        The 1/4" x 5/8" sizing matches common mid-range residential and light commercial split systems. Check the system's installation manual or rating plate for the required liquid and suction line sizes. Sparky Direct stocks four sizes: 1/4 x 3/8, 1/4 x 1/2, 1/4 x 5/8, and 3/8 x 3/4 inches. Choosing the wrong size reduces cooling efficiency and may damage the compressor.

        The BPC1458 features heavy-duty triple-layer insulation with UV-resistant outer layer, dew point proofing to prevent condensation, and a temperature range from -40°C to +105°C. Standard pair coil often lacks this protection and is not suitable for extreme climates. The triple-layer design also minimises heat loss and improves overall system efficiency.

        The BPC1458 carries a manufacturer's warranty of 1 year from invoice date for both domestic and commercial use, covering defects in materials and workmanship. Warranty conditions and claim procedures are documented on your invoice or product packaging. Warranties are void if the product is installed by an unlicensed technician.

        The BPC1458 arrives as a flat coil and can be bent on site to match the run between indoor and outdoor units. The flexible design allows smooth bending without kinking or insulation splitting. Use gentle bends and avoid sharp angles; sharp bends can restrict refrigerant flow.

        The BPC1458 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.
