Replace an old and worn out nylon head or bring a softer touch to tire mounting by replacing a standard steel mount head with this STEELMAN 14-970 Replacement Nylon Duckhead Mount / Demount Head Kit for Coats tire changers. Designed and molded to quickly and easily mount and demount tires, this replacement’s high pressure nylon construction allows it to be used on aftermarket alloy wheels and high performance rims without having to worry about damage. The head’s mounting hole is tapered to allow it to snugly fit onto machines fitted with tapered tip slide shafts. Similar in size and design to the standard Coats 8183061 Duckhead and is compatible with Coats RC-45, RC-55, X-Series, and GTS Series tire changers.
