The low pressure bonding option adds a second pressure range to the TCRS Piston Bonder to allow for apply pressure as low as 25 PSI and still retain the normal operating range of the machine, 70 – 120 PSI. This option is required for proper adhesion of the glue and clutch material on many smaller converters like Honda’s. It is availabe with new machines as well as a retrofit for existing 8in. and 10in. bonders.
