But for fleets chasing better uptime and fewer surprise breakdowns, the humble air line setup is worth a second look. Together, they create a complete air line connection system built for what Australian roads actually throw at a truck. SUPERCOIL reduces strain on the air line, while CLIPLOCK helps ensure the connection remains secure. Rather than treating coils and couplings as separate replacement items, fleets can upgrade the entire air line connection system in one step. Together, they form a complete air line connection system designed to improve durability, safety and reliability.
