Additional Information

In-Line Maintenance

Valve completely disassembles In-Line. Remove Handle "A", slide stem out for cleaning or O-ring replacement. Reassemble, and in minutes you're back in operation. All Valve styles have this feature.

Note: Threaded connections use Teflon thread tape. Apply to male thread of pipe to give complete thread coating. Make up hand tight. Then strap wrench 1/2 to 1 turn only.

Note: Excessive tightening will weaken thread and cause leaking joint. Do not use pipe wrench or pliers, as they will scar and weaken the material. Strap wrenches supply sufficient torque.
