High quality German thermostat o-ring to seal your thermostat in its housing.  The profile of this o-ring has squared edges, which we have consistently found to seal better than the round profile.  

Fits 1983-1991 Vans with 1.9L and 2.1L engines only. Will not fit diesel Vanagons.

NOTE: Thermostats often come with o-rings but may not use this square profile style.  Consider using this o-ring instead of whatever comes with your t-stat.
