4650-001 - Robert Shaw Stuffing Box Kit

Add-on stuffing box kits are used when an application requires a stuffing box and the replacement control does not have one built-on. These add-on stuffing box kits are designed to fit all capillaries and will fit all sensing bulbs up to 3/8" inch diameter. They are designed to convert a standard (non-stuffing box) control to fit a stuffing box application.
