        TuffStuff | Copper Crimp Link 35mm² | Inline Conductor Joiner

        The TuffStuff CLINK35 is a copper crimp link that joins or terminates 35mm² stranded copper conductors through mechanical compression. The CLINK35 is supplied as a single inline link, crimped onto the conductor with a correctly sized die to form a copper-to-copper joint. It is a bare copper barrel finished in natural metallic copper and is sold individually.

        Joining or extending a 35mm² conductor at the switchboard or along a sub-main run demands a solid, low-resistance termination. A connection that is loose or poorly formed on a conductor this size develops heat under load and is flagged at inspection. The CLINK35 delivers a compression joint matched to the 35mm² conductor, gripping every copper strand along the full barrel. This keeps contact resistance low and holds the termination cool under heavy current.

        For a licensed electrician, the crimp link forms a large-conductor termination quickly once the correct die is selected. The CLINK35 compresses in a single operation and accepts heat shrink directly over the barrel for insulation. Carrying several link sizes on the van means a mains or earthing termination is completed on site without a return visit. The exposed copper barrel also lets the finished crimp be inspected before insulation is applied.

        Features

        • Solid copper barrel — the CLINK35 is formed from solid copper for good conductivity and corrosion resistance on current-carrying joints.
        • Sized for 35mm² — the barrel suits 35mm² stranded copper conductors, matching the strand bundle to the crimp bore.
        • Inline joiner format — joins two conductor ends butt-to-butt in a straight run, or terminates a single conductor end.
        • Mechanical compression — the link is crimped with a correctly sized die to form a gas-tight copper-to-copper connection.
        • Corrosion-resistant copper — copper resists surface corrosion, so the joint holds its contact over time in dry enclosures.
        • Natural metallic finish — the CLINK35 is supplied as a bare copper link with no plating or colour coating.
        • Single-buy packaging — supplied one link per pack, so the exact quantity for a job can be ordered.
        • Crimp tool required — the CLINK35 is a compression fitting and must be crimped with a matching die, not pushed or screwed on.
        • Insulation separate — the link is bare copper and needs heat shrink or tape applied over the finished crimp.
        • Copper conductors only — the link is intended for copper conductors, not aluminium conductor joins.
        • Open barrel bore — the straight barrel lets both conductor ends seat fully before crimping.

        Where to use

        • Sub-main conductor joins — joining 35mm² copper sub-main conductors where a run is extended or repaired.
        • Main earthing conductors — terminating or joining 35mm² copper earth conductors at the board or earth bar area.
        • Consumer mains repairs — the CLINK35 rejoins a damaged 35mm² copper conductor where a section is cut out and replaced.
        • Battery and inverter cabling — joining heavy 35mm² copper battery or inverter leads in solar and backup setups.
        • Switchboard build work — making off 35mm² copper links inside enclosures during board assembly.
        • High-current DC runs — the CLINK35 joins large copper conductors in 12V and 24V high-current wiring.

        The CLINK35 is sized for 35mm² conductors only and should not be forced onto smaller or larger cable. It is for copper conductors, not aluminium, and is a bare link that must be insulated after crimping. Fixed wiring connections must be made by a licensed electrician.

        (CLINK35)

        The TuffStuff CLINK35 is sized for 35mm² stranded copper conductors. The barrel is made to take the strand bundle of a 35mm² conductor, so the conductor should match that size for a correct crimp. Other conductor sizes use a different link.

        The CLINK35 is a compression link and needs a crimping tool fitted with a die sized for 35mm² copper. Hydraulic or mechanical crimpers both work, provided the die matches the barrel. The link is not a push-fit or screw connector, so a crimp is required.

        The CLINK35 is a copper link intended for copper conductors. Joining aluminium conductors calls for a connector rated for aluminium or for bi-metal use, because copper and aluminium react at the joint. Use the copper link on copper conductors only.

        A copper crimp link joins two conductor ends butt-to-butt inside one barrel, forming an inline splice. Each conductor is inserted from one end until the strands meet near the centre, then both sides are crimped. The result is a single copper-to-copper joint along the run.

        The copper crimp link is supplied as a bare copper barrel with no insulation. Heat shrink or insulating tape is applied over the finished crimp to cover the exposed copper. Sizing the heat shrink to slide over the barrel before crimping makes the cover-up simpler.

        The TuffStuff CLINK35 carries a one-year warranty for both domestic and commercial use, running from the invoice date, with returns handled back to Sparky Direct. Warranty cover applies where the product is installed by a licensed electrician, in line with the standard warranty terms.

        TuffStuff copper crimp links come in a range of conductor sizes, including the CLINK6, CLINK16, CLINK25, CLINK50, CLINK70 and CLINK95. Each size matches a specific conductor, so the link is chosen to suit the conductor being joined. The 35mm version is the CLINK35.

        The TuffStuff CLINK35 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.
