3/4 inch Galvanized Iron Cap

3/4" Galvanized Iron Cap – Threaded Fitting for Secure Line Termination

The 3/4" Galvanized Iron Cap is designed to seal the end of a galvanized pipe run, providing a strong and corrosion-resistant closure point. Manufactured to meet stringent dimensional and pressure specifications, this fitting is a dependable choice for contractors working in water supply and low-pressure steam systems.

Product Advantages

• ✅ Hot-Dipped Galvanized Finish Offers superior resistance to corrosion and rust, extending service life in wet or humid environments.
• ✅ Threaded FNPT Connection Standard 3/4" female National Pipe Thread (NPT) provides a tight mechanical seal with compatible steel piping.
• ✅ Cast Iron Core Durable construction maintains structural integrity under operating pressure and temperature fluctuations.
• ✅ Uniform Wall Thickness Enhances mechanical strength and ensures even thread engagement during installation.
• ✅ ANSI/ASME Compliance Produced to meet or exceed ASME B16.3 and ASTM A197 specifications for malleable iron pipe fittings.

Installation Guidance

Installation of this cap is straightforward. Apply thread sealant or PTFE tape to the male threads of the mating pipe to ensure a leak-free seal. Tighten the cap with a pipe wrench while taking care not to overtighten, which can compromise threads. Suitable for both vertical and horizontal applications, depending on system design.

Technical Details

• Material: Galvanized malleable iron
• Size: 3/4 inch nominal pipe size
• Connection Type: Female NPT
• Pressure Rating: Up to 150 psi for water, oil, or gas systems (WOG)
• Standards: ASME B16.3, ASTM A197, ANSI B1.20.1

Typical Applications

This fitting is typically used in plumbing and mechanical systems to terminate the end of a pipe segment. It’s well-suited for use in water distribution, low-pressure gas lines, and compressed air systems where a corrosion-resistant seal is required.

Industry Note

Galvanized iron pipe and fittings are commonly selected for outdoor or exposed installations due to their enhanced resistance to environmental degradation. Proper sealing and thread engagement are critical to avoid seepage or failure at threaded joints.

The 3/4" Galvanized Iron Cap delivers long-term performance in a range of residential and light commercial applications. For contractors seeking durable, code-compliant solutions, this fitting provides a secure and cost-effective way to terminate galvanized pipe runs.
