1/4 inch Galvanized Iron 90 Degree Elbow Female x Female

1/4 inch Galvanized Malleable Iron 90° Elbow – Threaded Fitting for Low-Pressure Piping Systems

The 1/4 inch Galvanized Malleable Iron 90° Elbow is a threaded fitting used to change direction in pipe runs by 90 degrees. Manufactured from ASTM A197 malleable iron and hot-dip galvanized per ASTM A153, this elbow is designed for general-purpose plumbing, air, and low-pressure water distribution systems.

With female National Pipe Taper (NPT) threads on both ends, the fitting connects two male-threaded pipes at a right angle. The galvanized coating provides corrosion resistance, making it suitable for interior and select exterior applications where moisture or condensation may be present.

Technical Specifications

• Material: Galvanized Malleable Iron
• Nominal Size: 1/4 inch
• Connection Type: NPT Female x NPT Female
• Bend Angle: 90 Degrees
• Compliance: Meets ASME B16.3 and ANSI B1.20.1; galvanized coating per ASTM A153
• Pressure Rating: 150 PSI for steam, 300 PSI for non-shock water/oil/air service

Installation Guidelines

Use with standard malleable iron or steel pipe and apply a compatible pipe joint compound or PTFE tape for sealing. Avoid over-tightening to maintain thread integrity and prevent stress on the fitting. Always follow local code requirements and system pressure testing procedures before commissioning the system.

Applications

This elbow is commonly used in water supply lines, HVAC piping, air compressor systems, and general industrial applications. It is ideal for directional changes in confined installations or wherever structural routing constraints require a 90-degree turn.

Material Insight

Galvanized malleable iron provides both mechanical strength and corrosion protection in non-potable systems. The zinc coating extends the service life in mildly corrosive environments while preserving the fitting's structural integrity under fluctuating temperature and pressure conditions.
