ABSTRACT:
A fitting for safe on-stream addition of valve packing which comprises a housing enclosing a first and second chamber each chamber associated with a means for ejecting valve packing, the first chamber being accessible from the valve when the fitting is mounted and also accessible from the second chamber through sealable portals, and the second chamber having a sealable entrance to receive valve packing, thereby enabling safe addition of valve packing to a valve through the valve gland by: sealing the first chamber, adding valve packing to the second chamber and sealing the second chamber, opening the access portal between the chambers and ejecting the valve packing from the second chamber into the first chamber, sealing the access portal between the chambers and opening the portal between the first chamber and the valve, and ejecting the valve packing from the first chamber into the valve.
