Stainless Steel 316 Close Taper Nipples 150lb
When a connection has to hold, in saltwater air, chemical lines, or high-heat plumbing,- the fitting you choose makes all the difference. Built from Grade 316 stainless steel, these Close Taper Nipples resist rust, corrosion, and chemical degradation in environments where standard steel fittings deteriorate fast. That's why engineers and tradespeople reach for marine-grade 316 when the job demands long-term reliability. The close taper design runs threads along the entire body, leaving virtually no unthreaded gap in the middle. This allows the male taper threads to jam together and self-seal under pressure, no extra fittings, no added length. For tight installations where two female threaded components need to sit face to face with minimal clearance, these nipples are the go-to solution. Rated at 150lb pressure class, they're built to handle standard low pressure systems up to 150 psi across a wide range of applications, hot and cold water plumbing, oil, gas, and chemical transport lines, marine installations, and outdoor fluid systems. The short, stubby profile keeps your pipework compact without compromising the integrity of the connection.
