2H Exhaust Manifold Slip Joint O Ring LandCruiser HJ47 HJ60 HJ75

Slip joint O-ring seal for Toyota 2H exhaust manifold.

Used to seal the join between manifold sections and prevent exhaust leaks.

This O-ring is used in the exhaust manifold slip joint on Toyota 2H diesel engines.

 

The 2H manifold is a multi-piece design with a slip joint to allow for heat expansion. This ring sits between the sections and provides a seal.

 

Its role is to:

 

• Seal exhaust gases at the manifold joint
• Allow movement during thermal expansion
• Prevent exhaust leaks and noise

 

 

These engines rely on this joint design to avoid cracking the manifold under heat cycling.

Common Questions

 

 

Where does this go?

Between the two sections of the exhaust manifold at the slip joint.

 

How many do I need?

Two per engine.

 

Is this the manifold gasket?

No — this is for the slip joint, not the head flange.

 

What happens if it fails?

Exhaust leak, ticking noise, soot around manifold.
