Finish Thompson J100073 Ball Valve
The J100073 is the ball valve used in Finish Thompson M6 and M6X drum pump air motors. It is the on and off control in the air supply line to the motor, and it is what the operator actually uses to start and stop pumping.
Treat it as a service item rather than a permanent fitting. Valves are replaced when the handle becomes stiff, when the valve will not shut off fully, or when air leaks past the stem. When ordering, match the part to the pump as it was actually built rather than to the catalog model alone, since material and size options were specified at the time of purchase.

Frequently Asked Questions
Q: How should the pump be flushed before service?
With a fluid known to be compatible, so the parts can be handled safely and the old chemical is not carried into the rebuild.
Q: Can the pump be run briefly without this part?
No. Every component in the wet end carries a load or seals a joint, and running incomplete risks far costlier damage.
Q: Is this the genuine manufacturer part?
Yes. It is the factory component built to the original specification rather than a pattern copy.
Q: Should anything else be replaced at the same time?
Whatever the teardown exposes. Elastomers and bushings are inexpensive and are best renewed while the pump is already apart.
