McFarlane’s Cowl Saver Baffle Seal Receives an Upgrade


McFarlane Cowl Saver Baffle Seal

McFarlane Aviation Products released Cowl Saver several years ago. Following on the popularity of their low friction Cowl Saver seal material, McFarlane now also offers Cowl Saver with Bi-Flex Technology. Bi-Flex uses a laser engraved flex pattern to ensure an optimum combination of flexibility and stiffness for maximum cooling. The engraved pattern provides extreme flexibility at the cowl for the best seal, while the non-engraved area retains rigidity to prevent the baffle seal from blowing past the proper seal position against the cowl.

Like all Cowl Saver material, Cowl Saver with Bi-Flex Technology has 30 times less friction compared to standard silicone material, reducing the damaging effects of vibration transfer to engine cowls. The innovative material is available in three inch wide rolls (with or without attaching hardware) or as FAA-PMA pre-cut baffle seal kits for Cessna 172Q, R, and S models.

New Tool Allows for Even More Customization

Cowl Saver baffle seals may be further customized before or after installation with McFarlane’s new Cowl Saver Scoring Tool. The tool uses three precision blades to score the Teflon surface of the Cowl Saver material to add flexibility just where it is needed, while maintaining rigidity elsewhere to prevent baffle seal blow by. The Scoring Tool can be used on both standard and Bi-Flex Cowl Saver material to create complex flex points for improved seal to cowl mating. The precision blades of TOOL120 allow for an exact cut depth.
