Flexfab 7701-175, 1.75" ID x 3 ft Fiberglass Reinforced Turbo Sleeve, 44mm 500F Turbo Charge Air

Connect your turbocharger to the engine with the Flexfab 7701-175 fiberglass reinforced turbo sleeve — a 1.75" ID silicone sleeve engineered for the extreme heat of charge-air and exhaust-side service. It resists chemicals, steam, coolants, ozone, and aging that destroy ordinary hose.

Why this Flexfab turbo sleeve

• 3-ply silicone-coated fiberglass construction — extreme temperature resistance for hostile engine environments.
• −65°F to +500°F range — handles post-turbo heat without hardening, cracking, or failing.
• 105 PSI burst / 35 PSI max operating — a solid margin for boost-side use.
• Resists chemicals, steam, coolants, ozone & UV — long service life under the hood.
• 1.75" (44mm) ID, .080"/.110" wall, 3 feet length — sized for turbo plumbing.

Designed for connection between the turbocharger and engine where no vibration is present. Pair with appropriate T-bolt clamps for a secure seal.
