6 Seat Gasket Installation
6.1 Wipe the gland seat gasket
groove clean with alcohol.
Caution:
Consult material safety data
sheets for proper handling of alcohol.
6.2 Install the seat gasket into the
groove. Hold the seat gasket
in the groove and adjust it so
the end extends 0.025 to 0.035
inch (0.65 to 0.90 mm) past the
gland joint surface.
See Figure 18.
6.3 Check the gasket extension with
the 0.030 inch (0.76 mm)
"Proud" gauge. See Figure 19.
6.4 Pull back 0.50 inch (12.7 mm) of
the seat gasket. Use a paper
clip to put two dots of adhesive
in the groove approximately
0.25 inch (6.35 mm) and 0.50
inch (12.7 mm) from the gland
joint surface. See Figure 20.
6.5 Push the end into the adhesive
and check the gasket extension
with the "Proud" gauge. Hold it
in place for 10 seconds.
See Figure 21.
6.6 Glue the other seat gasket end
into the groove using the same
steps.
6.7 Push the middle of the gasket
into the groove. Do not apply
adhesive.
6.8 Repeat this procedure for the
other gland half.
