Is this product factory new?
Yes, all RPI RXO065 O-Rings are factory new and sourced directly from the manufacturer to ensure complete reliability and product integrity.
How should I plan for maintenance with this part?
Given that these are critical seals for 3/4” filter housings, we recommend keeping this 2-pack on hand during scheduled service intervals. As this is an essential part of the WCE003 Filter Element assembly, replacing the O-Ring during your filter changes helps prevent leaks and maintains optimal system pressure.
