SPOOLOGIC Turbo Flange Gasket

The SPOOLOGIC SL-310-004 Turbo Flange Gasket seals the exhaust inlet connection at the turbocharger on 1994–1997 Ford 7.3L Powerstroke OBS trucks. It provides a replacement sealing gasket for the original turbo inlet flange when the connection is opened for service or an exhaust leak is confirmed at that joint.

Features

• Replacement gasket for the turbocharger exhaust inlet flange
• Seals the connection carrying exhaust gas into the turbine housing
• Supplied individually for a single flange connection
• Uses the existing flange mounting arrangement

Turbo Exhaust Inlet Sealing

The exhaust inlet connection directs exhaust gas into the turbine housing. A damaged gasket or an uneven mating surface can allow exhaust to escape before it reaches the turbine. Soot around the joint, exhaust noise, or reduced boost response can indicate a leak, but the connection should be inspected before replacing parts.

This gasket serves the exhaust side of the turbocharger. The turbo pedestal oil passages and compressor outlet use separate seals.
