CS085X3X108GBF COWL SAVER, BI-FLEX, 3" X 108"

The **McFarlane CS085X3X108GBF Cowl Saver** is a **baffle‑seal material** intended for aircraft engine cowlings. Supplied as a **3‑inch wide roll, 108‑inch (9‑ft) long, 0.085" thick**, it can be cut as needed to produce custom straight or slightly contoured baffle seals. Featuring **Bi‑Flex™ technology**, one side of the material is silicone, while the other is a **low‑friction Teflon‑coated rubber** — this dual‑surface construction substantially reduces friction against the cowl interior. This reduced friction helps **minimise vibration transfer, cowl skin fatigue, fastener wear, and firewall/cowl cracking**, improving longevity of the firewall‑forward structure. The material is **fiberglass‑reinforced** to balance flexibility (for sealing) and stiffness (to prevent seal blow‑back under engine airflow). --- ## Applications - Fabrication or replacement of engine‑cowl baffle seals in general‑aviation aircraft - Ideal for cowls requiring moderate length or straight seals where a 3‑inch roll is sufficient - Useful during cowl maintenance, overhauls, or seal replacements to reduce vibration and structural stress - Suitable for owners/operators seeking longer‑lasting seals and easier cowling reinstallation --- ## Why CJ Aerospace?

- **Bi‑Flex™ baffle‑seal material** — silicone base with Teflon‑coated, low‑friction surface on the contact side - **Fiberglass‑reinforced sheet** — provides a balance between flexibility to seal cowling contours and stiffness to resist seal blow‑by - **9 ft roll (3″ × 108″)** — sufficient for many single‑engine or light twin cowls with straight seal runs - **Reduces engine vibration transfer to cowl and firewall**, mitigating fatigue, fastener wear, and structural cracking - **Simplifies fabrication of custom‑length seals** without need for multiple strips or pre‑formed seals
