Achieve maximum exhaust performance in heavy-duty casting applications with the Brass 20mm Core Box Air Vent from Radhe Industries. Designed for massive core box cavities and high-volume core-blowing machinery, our 20mm air vents provide ultra-wide surface area venting, allowing trapped air and curing gases to purge instantly without letting resin-coated sand breach the vent profile.
Manufactured directly in Jamnagar using premium, industrial-grade brass alloys, our 20mm vents offer exceptional structural integrity, high thermal resistance, and precise dimensional stability under extreme compaction pressures and repetitive thermal shocks.
Maximum Surface Area Exhaust: The extra-wide 20mm profile provides peak venting capacity for large-scale or deep core cavities, completely eliminating gas porosity, internal voids, and soft sand cores.
Tight Press-Fit Tolerance (0.01 mm): CNC-machined for precise outer dimensions to guarantee a flush, secure seating in 20mm pre-drilled core boxes without drift or loosening under vibration.
100% Verified Alloy Purity: Every melt undergoes strict spectroscopic analysis to guarantee ideal metallurgical composition that withstands thermal shock and mechanical fatigue.
Resistant to Chemical Erosion: Built to withstand aggressive cold-box amine gases, binder chemistries, core washes, and moisture without degrading or oxidizing.
Anti-Clogging Design: Smooth micro-slot geometry prevents sand buildup, extending tool life and making routine inline cleaning quick and easy.
