        Sparky Direct | AC Pair Coil 1/4 x 1/2 Heavy Duty 20m | R410A and R32 Compatible

        The Sparky Direct BPC1412 is a heavy-duty insulated pair coil that joins the indoor and outdoor units of a split-system air conditioner. It pairs a 1/4 inch and a 1/2 inch annealed copper line in a single 20 metre roll, rated for R410A and R32 refrigerants. The BPC1412 complies with AS/NZS 1571 and carries an EN 13501-1:2007 fire classification of D-s3-d0.

        Connecting a split system means running two refrigerant lines between the wall units, and sourcing separate copper and lagging adds cost and handling on site. The BPC1412 supplies both lines pre-insulated as one 20 metre pair coil, so the liquid and suction runs arrive ready to flare and connect. The 1/4 x 1/2 sizing matches the most common small and mid-size split systems specified for homes and light commercial work.

        Installers reach for a pre-paired coil because it cuts the line set to one pull instead of two separate copper runs through the wall cavity. The annealed copper flares cleanly and bends to the route without kinking, and the triple-layer insulation stays put, so there is no taping a second layer of lagging over bare pipe. Ordering both lines as a single pre-paired set keeps the material count low and the install tidy on a fixed-price job.

        Features

        • Pre-paired line set — the BPC1412 joins a 1/4 inch and 1/2 inch annealed copper line in one coil, covering both refrigerant runs for a split-system connection.
        • 20 metre roll — a single length covers the line run on most domestic and light commercial installs without a join.
        • R410A and R32 rated — works with current split systems running R410A or the lower-GWP R32 refrigerant.
        • Triple-layer insulation — an embossed outer skin, a polyethylene foam core, and a closed-cell cross-linked inner layer wrap the copper for thermal protection.
        • Wide insulation range — the BPC1412 lagging holds its rated performance from -40 to 105 degrees Celsius, covering hot roof spaces and cold climates.
        • UV-resistant outer layer — the embossed skin resists ageing, cracking, and water entry where the coil runs in exposed sections.
        • Annealed copper tube — soft copper bends to the route and flares without kinking, and complies with AS/NZS 1571.
        • Condensation control — close contact between tube and foam supports dew point proofing and limits sweating along the run.
        • Fire classification — the insulation carries an EN 13501-1:2007 rating of D-s3-d0.
        • Fixed 1/4 x 1/2 size — the BPC1412 does not suit systems specified for larger 5/8 or 3/4 line sizes.
        • Black insulation finish — the black outer skin suits external wall runs and pairs with standard ducting and capping.

        Where to use

        • Residential split-system installs — the BPC1412 connects a wall-mounted head unit to the outdoor condenser on single-room and multi-room homes.
        • Light commercial fit-outs — offices, shops, and consult rooms running small to mid-size split systems on 1/4 x 1/2 line sizes.
        • New air conditioning installs — first-fit refrigerant runs where the line set is pulled in during construction or renovation.
        • System replacements — the BPC1412 re-runs fresh insulated copper when an old unit is swapped and the existing line set is past its service life.
        • Exposed external runs — the UV-resistant outer layer suits wall runs between the head unit and condenser before capping is fitted.
        • Hot roof spaces and ceiling voids — the wide insulation range handles high cavity temperatures over summer.
        • Regional and rental property work — a full 20 metre roll covers the run without a mid-line join on most jobs.

        The BPC1412 is fixed at 1/4 x 1/2 and is not suited to systems specified for 5/8 or 3/4 line sizes. It carries refrigerant between the units only and is not a drain line, data, or power cable. Flaring, brazing, and the final connection must be carried out by a licensed air conditioning installer.

        Verified Sparky Direct customer reviews: AC Pair Coil 1/4 x 1/2 Heavy Duty Insulated Copper 410a / R32 20m (BPC1412)

        "Great product and at half the price of individual pipes." — Peter

        "Flexible, perfect flaring, easy fit" — Anonymous

        (BPC1412)

        The BPC1412 uses annealed copper that complies with AS/NZS 1571, and the insulation carries an EN 13501-1:2007 fire classification of D-s3-d0. This makes it suitable for refrigerant line runs on standard residential and light commercial split-system installs.

        Flaring, brazing, and connecting the copper lines to a split system must be carried out by a licensed air conditioning installer or refrigeration technician. The pre-paired coil pulls through the wall cavity as one set, then each line is flared and joined at the indoor and outdoor units.

        The BPC1412 is rated for R410A and R32, the refrigerants used in most current split systems. The 1/4 inch and 1/2 inch line sizes suit common small and mid-size units. Check the system data plate to confirm it calls for 1/4 x 1/2 lines before ordering.

        The numbers are the outside diameters of the two copper lines in inches: a 1/4 inch liquid line and a 1/2 inch suction line. Split systems are specified by these line sizes, so the coil must match what the unit installation manual calls for.

        Three layers wrap the copper: an embossed UV-resistant outer skin, a polyethylene foam middle layer, and a closed-cell cross-linked inner foam. Together they hold the rated insulation performance from -40 to 105 degrees Celsius and limit condensation along the run.

        The embossed outer layer resists UV, ageing, and cracking, so the lagging stays intact on exposed wall runs between the head unit and condenser. Fitting ducting or capping over external sections still gives the best long-term protection from sun and weather.

        The BPC1412 carries a one-year warranty for domestic use and a one-year warranty for commercial use, starting from the invoice date, handled as a return to Sparky Direct. Warranties are void if the product is not installed by a licensed installer.

        Sparky Direct stocks pair coil in other size combinations, including 1/4 x 3/8 (BPC1438), 1/4 x 5/8 (BPC1458), 3/8 x 5/8 (BPC3858), and 3/8 x 3/4 (BPC3834). Match the line sizes to what the split system installation manual specifies.

        The Sparky Direct BPC1412 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.
