Hex Nipple Pipe Fitting BVV™ brand stainless steel parts are made with precision 304 Grade Stainless Steel and are clean and free from burrs or debris. These fittings are NPT threads (National Pipe Taper) and will compress against other Female/Male NPT threads creating a tighter and tighter connection. All NPT threads require thread sealant to create a watertight and gas-tight seal between the threads. We recommend using Yellow Gas PTFE Tape because it is rated for gases and is UL listed and it is NOT recommended to use white PTFE tape because it is not rated for gas service. **NOTE: Pre-Taped option comes from BVV Pre-taped with Yellow UL Listed Gas PTFE Tape on the Male NPT threads ONLY for a +0.50c charge per male npt end. (JIC Threads DO NOT need to be taped.) Hex Nipples allow the user to connect 2 female NPT fittings together and also have the ability to put a wrench on the middle portion of the fitting because of the hex wrench section.
