Designed for moulding In Situ rings on the stuffing box, just by wrapping suitable width and length of tape on the stem or shaft to achieve sealing. With a tamping tool and gland follower torques end less rings can be formed on site. These are self lubricating and inert to serve as universal sealing tape on stuffing boxes. This tape is extremely handy, for emergencies when exact size packing is not available. Just four standard widths means reduction of inventory.
