McFarlane Aviation Products has introduced its Cowl Saver with Bi-Flex Technology.
Bi-Flex uses a laser-engraved flex pattern to ensure a combination of flexibility and stiffness for maximum cooling, according to company officials.
The engraved pattern provides 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, company officials explained.
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, company officials noted.
The material is available in 3 inch wide rolls (with or without attaching hardware) or as FAA-PMA pre-cut baffle seal kits for Cessna 172Q, R, and S models.
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, company officials said.
