This Bedford Precision Parts seal is an aftermarket replacement designed for high-duty spray systems.

Where it’s used

The U-cup installs in the displacement pump’s throat/rod area to maintain a solvent-resistant seal under pressure. Choose the Bedford 49-3647 U-Cup for paint sprayers during scheduled rebuilds or whenever you notice bypass, pressure fluctuation, or material creeping past the upper seal.
