Threaded NPT Hex Nipple

All stainless steel parts from Stainless Steel Express are free of burrs and debris and are developed with high-quality and durable 304 Grade Stainless Steel. All fittings are NPT threads (National Pipe Taper) and easily compress against other NPT threads that are Female and Male, ensuring a tighter and secure connection. Use thread sealant with NPT threads to create a water-tight and gas-tight seal between each thread. We recommend using tape that is rated for gases and is UL listed.

In addition, this Threaded NPT Hex Nipple Fitting also allows you to utilize a wrench on the middle. Hex nipples are available in sizes of ¼”, ⅜” X ¼”, ⅜”, ½” X ¼”, and ½” to meet your needs.
