VB-7XX3 and VB-7XX5 Threaded Valve Bodies
1. Apply pipe dope sparingly to all but the last two threads of a properly
threaded, reamed, and cleaned pipe. Make sure that pipe chips, scale, etc.
do not get into the pipe since this material may lodge in the valve seat and
prevent proper closing and opening of the valve.
2. Start the joint by hand screwing the pipe into the valve. If the thread en-
gagement feels “right,” turn the pipe by hand as far as it will go.
3. Use a pipe wrench to fully tighten the valve to the pipe. Do not over
tighten or strip threads.

the base the vise base.
5. Remove the copper tube from vise base and examine for splits. Bring the nut back to the end of the flared tubing.
