Installing the New Packing
Packing (A2) strip length and quantity are shown in Table B. DeZURIK provides extra packing in their
packing kits, but do not try to put more packing into a layer than shown in Table B.
Do not compress the packing any more than
needed to stop leaks.
1. Ensure the gate (A3) is well within and cen-
tered in the body before packing.
2. Place the anti-extrusion guides (A9) in the
bottom of the packing chamber (machined
slots).
3. Assemble and pack the rings one at a time,
with the ends together, but not overlapped
Note: Stagger the joints, on the long side of the
packing chamber. For packing rings, we
recommend using a square-ended wood or
plastic tool, driven by a hammer or mallet. Do
not use a sharp tool to pack the rings.
Ensure the inside and outside edges of each
ring are packed against the gate and packing
chamber, so that each strip is compressed flat
and evenly.
4. For packing systems with the packing cord
(A8), assemble and pack one row of packing
(A2) and then insert the packing cord (A8).
Assemble and pack the last row of packing.
