7W2326 Caterpillar oil filter（7W-2326）

Built for heavy-duty diesel engine lubrication systems, the 7W2326 Caterpillar oil filter offers high-precision particle capture and strong dirt-holding capacity. It efficiently removes metal debris, sludge, and abrasive impurities from engine oil, maintaining optimal cleanliness to cut friction on moving parts. This filter ensures low-resistance oil flow, shields crankshafts and bearings from wear, and preserves stable performance in high-load conditions.

Precision-made to strict dimensional standards, this filter allows direct replacement with no extra modification. For example, it is fully compatible with Caterpillar machinery and engine series, including:

It features high-density cellulose-synthetic blend filter media. Thanks to this design, it balances fine particle filtration with excellent oil flow efficiency. The rugged metal housing offers superior pressure and impact resistance, which withstands extreme engine vibration and temperature swings. A premium nitrile rubber seal creates a leak-proof fit, thereby preventing unfiltered oil bypass and ensuring long-term sealing reliability.

This filter achieves over 98.5% efficiency for particles ≥8 microns. In addition, it keeps engine oil pure and extends component service life. Its large dirt-holding capacity lengthens replacement cycles, thus cutting maintenance frequency and downtime, lowering operational costs for compact Caterpillar machinery. It performs consistently in dusty construction, landscaping, and light agricultural sites.

Designed for Caterpillar compact and mini heavy machinery, the 7W2326 oil filter is widely used in small construction, landscaping, agriculture, and light industrial work. All in all, it provides dependable lubrication system protection, minimizes engine wear risks, and supports steady, long-lasting operation during daily heavy-duty use.
