This NeuSprue® sprue and base assembly accommodates a 2-1/2" flask. The patented two-piece screw-on design secures a threaded sprue (see NeuSprue wax sprues) to the base, eliminating the risk of floating trees. Lift-off removal of the base prevents stress damage to the wax tree and patterns and prevents investment debris from falling into the wax void, causing defects. This base assembly is compatible with all Neutec casting machines and most other lost-wax casting machine brands. Includes:
• one rubber base
• one threaded plastic holder
• Not suitable for use with Flowlogic® casting machines.
