Product Details

The part number 502989 refers to a high-precision, internal oil filter element. It is widely used in central air conditioning systems, industrial chillers, and commercial refrigeration units to remove contaminants from the lubricating oil, protecting the compressor and ensuring stable cooling performance.

Outside Diameter (D): Approximately 76 mm (3.0 inches)

Height/Length: Approximately 167 mm (6.6 inches)

Thread Size: 3/4" UNF connection

Filter Media: High-grade pleated glass fiber (glassfiber) or resin-impregnated paper, providing maximum surface area and dirt-holding capacity.

Filtration Efficiency: Typically rated for 3 to 5 microns to capture micro-particles before they can wear down compressor bearings.

Structural Support: Built with a heavy-duty perforated steel or stainless steel inner core to withstand high pressure differentials without collapsing.

Included Components: Replacement kits usually include the filter element along with the required high-durability rubber sealing gaskets/O-rings.
