  • Packing tool and process
    Patent number: 10807221
    Abstract: An improved packing tool and process includes a mobile packing gland having a first end with a large opening that accepts a ring of packing material. The packing gland tapers down from the first end to a second end which is arranged within a static gland that receives the packing material which comprises a seal. A ring of packing material is arranged within the mobile packing gland and is inserted into a static gland with a pusher. The pusher exerts uniform pressure about the ring of packing material to seat it within the static gland. Thereafter the pusher is withdrawn from the mobile packing gland and successive rings of packing material are stacked within the static gland by repeating the process.
