Complete two-piece valve kit designed for efficient vacuum bagging composites, including 2 stainless steel valves and quick disconnect fittings. Simple x-shaped slit installation in the bag film allows fast, secure connection and helps reduce setup time in resin infusion projects. Ideal choice for high performance composite work, this high temperature disconnect fitting is tested to maintain 29 inches of mercury and 200 psi at up to 500°F. Dependable sealing performance supports prepreg fabrics, high temperature resin infusion, and other advanced curing conditions. Attractive, practical design features standard 1/4 inch NPT external threads on the vacuum bagging valve for easy connection to your existing system. The quick disconnect fitting includes 1/4 inch internal threads on both ends, supporting reliable, leak- couplings in varied setups. Constructed from 304 stainless steel with machining and a knurled for enhanced grip, this high temperature disconnect fitting delivers superior resistance versus aluminum, making it ideal for demanding composite layups using polyester or epoxy resins. Wide application across composite materials, whether you are working with carbon fiber, fiberglass, or hybrid laminates. This vacuum bagging valve for composites helps streamline material consolidation, making it easier to achieve consistent quality in panels, molds, and custom structural parts.
