1/2" × 7mm Core Box Air Vent

Product Overview

Achieve precise gas purging and optimal sand compaction with the Brass 1/2″ × 7mm Core Box Air Vent from Radhe Industries. Engineered specifically for core tooling requiring fractional imperial outer diameters with standard 7mm depth seating, this air vent allows trapped air and curing gases to escape instantly while keeping resin-coated sand securely inside the core cavity.

Manufactured in Jamnagar using high-tensile, corrosion-resistant brass alloys, our 1/2″ (12.7mm OD) vents deliver high structural strength, tight press-fit accuracy, and exceptional resistance to wear under continuous core-blowing pressure and thermal shock.

Key Features & Operational Benefits

  • High Airflow Efficiency: Engineered slot geometry allows rapid gas relief from the core box cavity, eliminating internal voids, blowholes, and soft spots in resin sand cores.

  • Micro-Tolerance Fit (+-0.01mm): Precision-turned outer diameter ensures a flush, tight press-fit into 1/2″ core box drillings without shifting under high blow pressure.

  • 100% In-House Material Purity: Every melt is verified by spectroscopic analysis to ensure robust metallurgical composition that withstands repetitive thermal cycling.

  • Corrosion & Chemical Resistance: Impervious to aggressive binder chemistries, cold-box amine gases, core washes, and atmospheric moisture.

  • Anti-Clogging Performance: Smooth micro-slots resist sand entrapment, speeding up routine maintenance and reducing production downtime.
