The Bridgeport 1104 1" Malleable Iron Conduit Nipple serves as a short raceway between enclosures or boxes when used with a locknut. The NPSM threads create a pressure-tight, vibration-resistant seal when the male and female threads compress and tighten. This nipple will fit on each end of the male thread while maintaining the integrity of the electrical connection. The malleable iron body has excellent tensile strength. Bridgeport conduit nipples come in a wide range of sizes and styles to provide complete installation flexibility, helping you install fast and deliver more. We engineer our conduit nipples with quality and innovation, allowing contractors to save time and money on every job. When you need quality electrical fittings for more efficient jobs, look for Bridgeport Orange.
