Product Description

AA48108-2 is an aircraft engine spin-on oil filter used for filtration of engine lubricating oil in piston aircraft engines. It incorporates Spin-EZ technology to maintain a lubricated seal that supports easier removal of the filter during routine engine maintenance.

0 1. Overview

The AA48108-2 Spin-EZ oil filter uses an adhered solid seal lubricant between the rubber seal and the engine mount pad so the lubricant remains in place under heat, time, and pressure. This construction prevents the bond-forming condition at the seal that is associated with difficult filter removal. The filter is produced as an OEM-supplied component for certain engine applications and is built with a full can thickness of 0.019 inch and a base plate thickness of 0.187 inch. It is rated for a burst pressure of 700 psi. For the -2 filter family, including 48103-2, 48108-2, and 48110-2, the filter media area is 311 square inches, while tall filters in the related family provide 460 square inches of media. For the AA48108-2 model, the nominal overall dimensions are 4 3/8 inches in height by 3 3/4 inches in diameter. The filter uses a 3/4-16 female thread and is installed to a torque range of 16 to 18 foot-pounds. The media is described as resin-impregnated cellulose with filtration efficiency of at least 99 percent at 25 microns. Stated operating pressure capability extends to 200 psi. The filter body weight is about 1.5 pounds with nominal product dimensions around 5 by 4 by 4 inches for handling and storage.
