Description
Overview:
This O Ring is a Genuine Loncin part for 2 inch (50.8 mm) water pumps, used to create a reliable seal within the pump assembly. Made from durable black elastomer, it helps prevent leaks by sealing mating surfaces so the pump can build and hold suction and discharge pressure. It is designed for Loncin portable water pumps used on site, farm, and home applications, including models such as LC50ZB23-3 and LC50ZB23-3.1Q. A correct, snug-fitting O Ring is essential for pump efficiency, easier starting, and consistent flow, especially after routine service such as impeller or volute cover removal. Manufactured to Loncin's specifications under part number 380840459-0001, this ring offers dependable performance and a straightforward replacement when the original seal is worn, flattened, or perished.
Key Features:
- Genuine Loncin component for assured fit and compatibility
- Sized for 2 inch (50.8 mm) water pump applications
- Forms a tight seal to reduce leaks and loss of prime
- Durable elastomer resists water exposure and general wear
- Helps maintain pump pressure and consistent output
- Smooth, round cross-section for even compression in the groove
- Straightforward to install during routine servicing
- Supports longer service intervals by reducing premature seal failures
Typical Applications:
Used to seal joints within Loncin 2 inch water pumps, such as the volute cover, pump casing, or inlet/outlet unions. Suitable for general water transfer, site dewatering, landscaping, irrigation, and flood response. Ideal when refurbishing pumps that have lost efficiency due to a flattened or damaged seal, or after cleaning and replacing the impeller where the housing must be resealed.
