- Attach the welding joint to the process pipe or chamber.
- Apply a sealant (MEGA-PIPE EXTRA No. 7188 or LOCTITE® No. 542 with activator No. 7649) on the threads of the welding joint and screw the bottom of the ball valve onto the welding joint.
Tighten the ball valve assembly by turning from the ball valve body.
CAUTION Tightening the ball valve kit by turning the extension nipple can break the sealing. Tighten the ball valve assembly only from the ball valve body.
- If you need to cap the ball valve assembly before installing or after removing the probe, attach a blanking nut to close the top of the valve.
