ROBERTSHAW - STUFFING BOX

3/8" STUFFING BOX - 4650-001
ADD-ON STUFFING BOX KITS AND ADAPTORS 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" in diameter. They are designed to convert a standard (non-stuffing box) control to fit a stuffing box application.
