Repair Instructions for Shutoff Models:
DB & B-375-A, GA, AT, & GAT
Please refer to the B-375-AT (REV-B) assembly drawing while following these instructions.
Required items: Repair kit #81277001 (1 ea.), a large bladed standard screw driver, a 3/32” hex key wrench,
#262 (red) Loctite, & Dow Corning #7 silicone grease.
Note: All o-rings should be lightly coated with Dow Corning #7 silicone grease prior to installation.
1. Remove the set screw (Item 17) located on the outlet end of the shutoff body (Item 8).
2. Remove the outlet adapter (Item 18) using a strap wrench or equivalent tool.
3. Remove the old adapter o-ring (Item 7) from the shutoff body and discard it.
4. Remove the old seat (Item 5) and o-ring (Item 6) from the outlet adapter and discard them.
5. Place the shutoff handle in the open position, as shown on the assembly drawing, and remove the valve
