Propane

This is the gasket that goes between the propane regulator and the small propane bottles that you screw on. Not ever offered as a separate Coleman part. The total diameter is 15/16 of an inch. The inner hole diameter is right between 5/16 and 3/8 of an inch.
This fits many applications for propane appliances.
