1/2″ x 8″ Galvanized Steel Pipe Nipple – Threaded, Schedule 40
The 1/2″ x 8″ galvanized steel nipple is a Schedule 40 threaded fitting designed for use in general plumbing, mechanical, and hydronic systems. Manufactured from welded steel pipe, this component is hot-dip galvanized to provide corrosion protection in both interior and exterior applications where rust resistance is essential.
Performance Characteristics
- Hot-Dip Galvanized Coating – Zinc coating provides a barrier against corrosion in moist or exposed environments.
- Threaded NPT Ends – Machined to ANSI B1.20.1 standards for compatibility with standard 1/2″ female pipe threads.
- Fabricated from Schedule 40 Pipe – Offers consistent wall thickness and strength suitable for moderate-pressure systems.
- Extended Length – 8″ body allows for bridging longer gaps or for use in custom-built assemblies where spacing is critical.
Specifications
- Nominal Pipe Size: 1/2 inch
- Length: 8 inches
- Material: Welded steel pipe, hot-dip galvanized
- Thread Type: NPT (National Pipe Tapered), both ends
- Standard Compliance: ASTM A53 / A733
Installation Notes
Thread sealant or PTFE tape should be applied to male threads prior to installation. Tighten using appropriate pipe wrenches without over-torquing to avoid thread deformation. This component is not intended for use in potable water systems in jurisdictions that require lead-free compliance under NSF 61-G or NSF 372.
Common Applications
Used for extensions and spacing in non-potable piping systems such as:
- • Hydronic heating circuits
- • Compressed air systems
- • General utility piping in commercial and industrial environments
- • Water supply lines where corrosion resistance is needed and code permits galvanized materials
Durability Insight
Galvanized steel nipples remain a contractor-preferred option in systems requiring cost-effective corrosion resistance. While not suitable for aggressive or acidic fluids, they perform reliably in standard atmospheric and wet conditions.
This 1/2″ x 8″ galvanized steel nipple is engineered to meet demanding system requirements while ensuring dimensional accuracy and installation consistency. Suitable for mechanical and plumbing professionals seeking dependable threaded connections in building systems.
