Polaris 3900 Sport O-ring Feed Hose Connector (48-141)
The o-ring for the feed hose connector is a replacement part made by Polaris. The same rubber material was used for the original factory part and is meant to be able to perform in the same capacities. Making it a genuine OEM product.
This o-ring was designed specifically for the vacuum tube/feedpipe assembly which takes on the role of being the object that helps pull and suck up dirt and debris into the superbag. It also is the connecting port for the feed hose connector which runs off the dedicated pressure line. This gives the 3900 Sport its power to clean the surface of your pool.
This part is black and is located on the feedpipe assembly which is located on the top of the cleaner next to the superbag. This o-ring is meant to be seated in a groove and compressed during the assembly between two or more parts. A great troubleshooting tip is that if the pressure coming from the line is weak or leaking where these parts meet then it may be worn or compromised. A replacement may be all that is needed to correct this issue.
