Heyco Products, Inc. Screw Grommets 3401VB

The Screw Grommet part number 3401VB from bisco industries features an integral sealing ring that ensures a reliable seal at the mounting hole, achieving IP 65, 67, and 68 ratings. It allows for air passage to equalize pressure while preventing moisture intrusion, making it liquid-tight. This product is UL rated for NEMA Type 3R, 4, and 4X applications. The grommet includes a hydrophobic and oleophobic filter membrane that protects electronic enclosures from moisture and particulate contamination. It is designed with a pressure compensating seal to mitigate pressure buildup due to temperature fluctuations. Installation is straightforward, accommodating both threaded and clearance holes, and it is made from electrically non-conductive Nylon 6/6. The grommet can snap into panel thicknesses up to 0.125 inches (3.2 mm) without tools, and it features six vent holes for effective ventilation. It is a cost-effective alternative to metal or steel plugs, with a head thickness of approximately 0.21 inches (5.3 mm).
