Standard Tri Ring Seat
1. Remove the Tri Ring seat by carefully cutting or using an o-
ring tool or pick to pull the seat out of the groove. Do not
scratch or nick the metal seating surface.
2. Clean the Tri Ring groove after removing the seat.
3. Lubricate the new Tri Ring (Figure 30, item A) with
acceptable cleansing solution or lubricant.
4. Place the stem through a 1-1/8 inch (30 mm) hole bored
through a board, or secure it with a vise with copper or
aluminum jaws.
5. Start the Tri Ring as shown in Figure 30.
6. Using the installation tool, part number 102797+ (Figure 30,
item B), press the Tri Ring into the plug at locations A, B, C,
and D (Figure 31). If this tool is not available, a dull, flat tool
can be used. DO NOT use a knife or any other sharp item
that will tear or cut the Tri Ring.
7. To finish installation, press small sections of the seal,
alternating from side to side (A-B-C-D), avoiding large loops
of seal.
8. When properly installed, the Tri Ring seat lip will protrude
slightly from the seat edge as shown in Figure 30.

face becomes damaged, purchase a new seat stem. Do not
