Product details
This replacement machine end coupling (part #IN3801) fits the Compact and TriStar Compact and connects the hose to the machine at the canister inlet. The coupling forms the sealed joint that carries suction from the machine into the hose.
A cracked or worn coupling leaks air and can pull loose from the inlet, which drops suction at the hose and interrupts cleaning. A fresh coupling reseals that joint so the hose locks in and moves full airflow again.
- Fits: Compact and TriStar Compact machines
- Part: machine end coupling #IN3801
- Function: connects the hose to the machine inlet
- Benefit: restores a secure, leak-free hose connection
The coupling fits the hose end for a direct-fit swap. Confirm your Compact or TriStar model before ordering so the coupling seats tightly at the inlet and holds under suction.
