Carbon Steel Pipe Nipple | NPT | Threaded Both Ends | Schedule 40 (3" x Close)

Key features

• HEAVY-DUTY INDUSTRIAL BUILD: Engineered from high-strength Schedule 40 carbon steel. These pipe nipples are designed for maximum durability in high-pressure environments, making them the preferred choice for professional gas, oil, and HVAC installations.
• NON-POTABLE USE ONLY: These black steel fittings are not for drinking water (potable water) lines. They are specifically designed for natural gas, propane, steam, and fire sprinkler systems where corrosion resistance is managed or the system is closed.
• PRECISION NPT THREADING: Features standard NPT (National Pipe Thread) TBE (Threaded Both Ends) for a tight, leak-proof seal. The deep-cut threads ensure a secure fit with all standard 150lb and 300lb malleable iron fittings.
• THE DIY STANDARD: These are the "go-to" components for industrial-style home décor. Perfect for building custom heavy-duty shelving, steampunk lighting, garment racks, and rustic furniture that requires a high-load capacity.
• SPECIFICATION COMPLIANT: Manufactured to meet ASTM A53 standards for welded carbon steel pipe. Every nipple undergoes rigorous quality control to ensure consistent wall thickness and thread accuracy.
