Finish Thompson J100014 Nitrile Coupling Insert
This is the factory nitrile coupling insert for Finish Thompson PF, PFS, TTC and TTS drum pumps. It sits between the two coupling halves and passes drive from the motor to the pump while absorbing shock and slight misalignment. It is built in nitrile rubber, which is what decides where it can safely be used.
It is one of the parts worth renewing on schedule instead of waiting for a fault. A perished or chewed insert shows up as a knock on start up and, once it breaks down completely, the motor spins without driving the pump at all. Check the pump build before ordering, because these pumps are offered in more than one material and size combination and the alternatives look similar on the shelf.

Frequently Asked Questions
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.
Q: What causes most premature failures on this part?
Running the pump outside what it was specified for, whether that is temperature, viscosity, dry running or an incompatible chemical.
