The ROLAIR vt447013 is a quick coupler designed for use with compatible air compressor systems. Quick couplers serve as the primary connection point between an air hose and a compressor outlet or pneumatic tool, allowing rapid connect and disconnect without tools. This coupler is a Rolair replacement part intended for technicians and trades professionals who service or repair Rolair compressor equipment. It restores proper hose connection function and maintains reliable airflow integrity at the coupling point.
This quick coupler is suited for use in compressed air systems found in HVAC service, plumbing, electrical, and general trade applications where a Rolair air compressor is part of the workflow. It is typically installed during routine maintenance or when an existing coupler shows wear, damage, or air leakage at the connection point.
Designed as an OEM-style replacement quick coupler for compatible Rolair air compressor models. Consult Rolair parts documentation to confirm fitment for your specific compressor model before ordering.
Installation should be performed by a qualified technician familiar with compressed air systems. Before replacing the coupler, shut off the compressor and fully depressurize the air tank and lines. Inspect the mating hose fitting and threads for wear or damage before installing the new coupler. Follow the compressor manufacturer's service documentation and applicable safety standards for compressed air equipment.
