Product Description
SET OF GASKETS 3-1/2" for PERFORATED FLASK
FOR VACUUM CASTING
SILICONE & GRAPHITE - GASKETS FOR 3-1/2" PERFORATED FLASKS
A set of 3-1/2" gaskets... High Grade Silicone and Graphite High Temperature gaskets.
Gaskets are used together to provide the best seal during vacuum casting to seal the perforated flask ring and casting chamber.
*** The Silicon acts as a sealing layer, while the graphite is placed on top of the silicone, protecting and prolonging the silicone seal from the high flask temperature.
The combination of the 2 types of gaskets provides a very good seal, allowing the vacuum to fully pull the molten metal into the flask.
These gaskets are die-cut, have a thickness of 1/8" for the Silicone and 1/16" for the Graphite.
Gaskets come in various diameters to work with individual flask OD sizes; visit our store.
