Discharge Flange Gasket for GT series 3in

The Discharge Flange Gasket for GT Series 3in (Part Number 1438G) is a precision stainless steel turbo flange gasket engineered for 4-bolt Garrett GT series turbochargers. This component seals the discharge outlet where the turbine housing connects to the exhaust system, preventing boost leakage and maintaining system integrity under high heat and pressure cycling. Proper sealing at the turbo discharge flange is critical for consistent boost delivery and preventing exhaust gas bypass that degrades turbo efficiency.

Manufactured from stainless steel, this gasket resists corrosion and thermal degradation in the extreme environment surrounding the turbo discharge. The 3-inch bore matches GT series turbo specifications, while the 4-bolt flange pattern ensures proper alignment and clamping force distribution across the sealing surface. At just 0.03 lbs with compact dimensions (4.45 x 0.65 x 5.5 inches), the gasket integrates cleanly into OEM or performance turbo installations without added weight or installation complications.

This is the replacement gasket for operators and technicians rebuilding or servicing Garrett GT series turbochargers on vehicles requiring boost system reliability. Whether performing routine maintenance, addressing an aging gasket failure, or assembling a fresh turbo setup, this OEM-specification component ensures the discharge flange seals correctly, preventing the performance loss and potential heat damage that result from exhaust leakage. It's a straightforward wear item that delivers no compromises on fitment or durability.
