Hot tub and spa wet ends are the parts that hold the impeller, they other wise known as impeller housings, they consist of 2 seals, 1 in-between the faceplate and body, and the other at the rear called a shaft seal (a white ceramic seal and a black carbon Seal combined). they are simple to replace and can sometimes be repaired.
Please note that all wet ends come without bolts to hold them onto the motors, these are sold separately.
