Challenge Cook Brothers 08 Gearbox O Ring

Challenge Cook Brothers 08 Gearbox O Ring

This product is a bulk length of 7/16" diameter O-ring cord stock made from oil-resistant Buna-N material. It is specifically intended for use with Challenge Cook Brothers (CCB) 08 series mixer gearboxes. Technicians cut the cord to the required length and bond the ends to form a custom-fit O-ring, typically for sealing gearbox housings or access ports during maintenance or rebuilds. This method is essential for creating large or non-standard seals that are not available as pre-formed rings.
