Barrel Nipple NPT Stainless Steel 316
Machined from Grade 316 stainless steel with added molybdenum for superior resistance to rust, salt water, and harsh chemicals, this fitting outlasts lower grade alternatives in marine, industrial, and high-moisture applications where standard metals corrode quickly. Its male NPT tapered threads on both ends follow American standard tolerances, wedging tightly into female threaded valves, elbows, or pipe runs to form a reliable, leak resistant seal when used with PTFE tape or thread sealant. The smooth, unthreaded barrel in the middle does more than just separate the two threaded ends,-it provides a clean gripping surface for a wrench, making installation straightforward even in tight or fixed layouts. Rated for temperatures up to 220°C and Class 150 pressure ratings, it safely handles water, oil, gas, air, and mild chemical media across a broad range of operating conditions.
Summary:
- Connects two female-threaded pipes or fittings, providing high corrosion resistance and a secure link in plumbing, marine, and industrial fluid systems
- Male tapered threads on both ends and a smooth, unthreaded barrel section in the middle
- Uses American standard tapered threads that wedge together to form a tight, leak-resistant seal when paired with thread sealant or PTFE tape
- Joins two female-threaded valves, elbows, or straight pipe runs together in tight or fixed layouts
- Handles water, oil, or gas lines exposed to moisture or salty air where standard metals would quickly corrode
- Transports fluids, air, or mild chemical mediums safely under high-temperature and moderate-pressure ranges (typically up to 220°C and class 150 ratings)
Applications:
Commonly used in;
- Piping & plumbing extensions
- Marine & Offshore environments
