BARREL NIPPLE – 316 STAINLESS STEEL

Barrel Nipple 150lb BSP Threaded Fitting – Marine-Grade 316 Stainless Steel (CF8M)

This 150lb BSP threaded fitting is engineered for demanding applications in marine, industrial, and commercial environments. Manufactured from premium marine-grade 316 stainless steel (CF8M), this fitting delivers outstanding resistance to rust, corrosion, and chemical exposure, making it ideal for use in harsh and corrosive environments such as saltwater systems, chemical processing plants, and high-moisture industrial zones.

Key Features:

• Material: Constructed from 316 stainless steel, also known as CF8M, which is widely recognized for its superior corrosion resistance and durability. This austenitic stainless steel contains molybdenum, enhancing its ability to resist pitting and crevice corrosion — especially in chloride-rich environments.

• Pressure Rating: Rated to 150lb class, this fitting is capable of handling pressures up to 1150 PSI (10.3 BAR). It’s designed for safe and reliable performance under significant operating pressures, whether in liquid or gas systems.

• Thread Configuration: Features BSPT (British Standard Pipe Taper) male threads on one end and BSPP (British Standard Pipe Parallel) female threads on the other. This allows for versatile and secure connections in compatible systems. The taper on the BSPT ensures a tight mechanical seal, especially when used with thread sealant or PTFE tape.

• Compliance & Standards: Manufactured to ISO standards, ensuring consistent quality, performance, and compatibility with international systems. The product meets rigorous criteria for dimensional accuracy and pressure performance.

• Application Versatility: This fitting is suitable for a wide range of applications:

  • Marine systems: Saltwater piping, bilge systems, desalination units, ballast systems, and engine cooling loops.

  • Water systems: Municipal plumbing, water treatment plants, irrigation systems, and potable water infrastructure.

  • Gas systems: Compatible with air and inert gases in compressed gas setups, HVAC systems, and industrial gas lines.

  • Industrial use: Chemical processing, pharmaceutical production, oil and gas, food-grade processing lines, and factory automation.

Why Choose 316 Stainless Steel?

Compared to the more common 304 stainless steel, 316 stainless includes molybdenum, making it significantly more resistant to pitting, oxidation, and harsh chemicals — particularly in chloride environments like marine or coastal areas. Its strength at high temperatures and toughness in cryogenic conditions add to its appeal for high-performance environments.

Built to Last

This BSP threaded fitting is built to perform in some of the toughest conditions. Its resistance to rust, acid, and chemical attack, combined with precise machining and a clean, professional finish, ensures long service life with minimal maintenance.

Installation Notes

• Always inspect threads for cleanliness before installation.

• For BSPT threads, use thread sealant or PTFE tape to ensure leak-proof connections.

• Tighten to specification using appropriate tools — avoid over-tightening which may cause thread damage or sealing failure.
