Cowl Saver™ Baffle Seal Material with Bi-Flex™ Technology
30x less friction than any other baffle seal on earth!
Reduce airframe vibration, stop cowl and firewall cracks
Baffle seal friction causes airframe vibration and destroys cowls
Typical silicone rubber baffle seals have a coefficient of friction among the highest of any known material. This friction transfers engine vibration into your cowl and firewall causing fastener fretting, fatigue, cracking, chafing and airframe vibration.
Cowl Saver™ has 30 times less friction!
- Dramatically reduces the friction between your cowl and baffle seals
- One side is silicone and the other is a low friction Teflon coated rubber
- Half of the engine vibration you feel in the cockpit is from baffle seal transfer
Low friction saves you money!
- Reduces transfer of vibration to the engine cowl and airframe
- Eliminates cowl erosion
- Extends baffle seal life
- Reduces expensive cowl and cowl fastener repairs
- Reduces fatigue and cracking in baffles, cowl skins and firewall
- Cowling even goes on easier!
- 36-month Money Back Guarantee!
Unbeatable performance
- Promotes superior engine cooling
- Ideal balance of flexibility and stiffness
- Fiberglass reinforced
- Meets industry standard AMS3320G
- Use scoring tool P/N TOOL120 for customized flexibility
Bi-Flex™ Technology
Precision laser engraved flex pattern ensures optimum flexibility/stiffness combination for maximum cooling and minimum friction.
