Description

Long lasting rubber base for 3″ diameter flasks. Used for spruing all types of trees and models. Often referred to as a style “C”, this base is very popular due to the rubber button former. Use a 3/8″ diameter sprue rod with this base.
Always use the correct diameter sprue base with the corresponding diameter flask you intend to cast with. To insure that you have a leak-proof seal, make certain that you have seated the flask onto the base and that the fit is tight prior to investing the flask.
