O-Ring Connections: General
WARNING: This page is about a different car, the 2001 Subaru Forester and 2000 Subaru Forester. However, it is still accessible from the selected car via links, so may be relevant.
The following points should be kept in mind when assembling O-ring connections:
- Avoid unnecessary handling and contact of O-rings with your hands, since even clean fingers contain body acids, which can contaminate the O-ring surface.
- Do not handle O-rings with gloves, shop towels, etc., since lint particles may cling to the O-ring, possibly causing a leak upon assembly.
- Always lubricate O-rings before assembly to allow the O-ring to seat itself properly.
- Be certain to use torque wrenches when tightening O-ring fittings, because overtightening can not only damage the O-ring, but it can distort the tube end as well.
