2 inch x 4 inch Galvanized Steel Nipple

1" Galvanized Steel Nipple – Threaded Pipe Fitting for Pressure Systems

The 1" Galvanized Steel Nipple is a straight, threaded pipe section designed to join two female-threaded fittings in pressurized fluid or gas systems. Manufactured from schedule 40 carbon steel and coated with a hot-dip galvanized zinc layer, this fitting provides enhanced corrosion resistance and is suitable for general-purpose plumbing, mechanical, and industrial installations.

This component is commonly used in piping systems where durability and code compliance are required, including potable water supply, fire protection systems, and compressed air lines. Threads conform to ANSI/ASME B1.20.1 NPT standards to ensure secure, consistent engagement during installation.

Product Features

• ✅ Material: Schedule 40 galvanized carbon steel
• ✅ Size: 1" nominal pipe size x custom cut length (e.g., 2-1/2", 4", 5")
• ✅ End Connections: NPT male threads both ends
• ✅ Corrosion Resistance: Zinc-coated exterior protects against rust in humid and wet environments
• ✅ Operating Pressure: Rated for use in systems up to 150 psi (dependent on system design and applicable standards)

Installation Notes

Proper thread engagement is critical for leak-free performance. Thread sealant (pipe dope) or PTFE tape should be applied to the male threads before assembly to ensure a secure seal. Do not overtighten, as this may cause thread deformation or cracking in connected components. Threads should be clean and undamaged prior to installation.

Applications

Common installations include:

• Water supply lines in residential and commercial buildings
• Low-pressure steam and air systems
• Outdoor spigots and irrigation piping exposed to weather conditions
• Fire sprinkler branch lines and manifolds (verify local code approval)

Specification Compliance

Meets ASTM A733 for pipe nipples and ASTM A53 for pipe material. Galvanized coating applied per ASTM A123 or equivalent hot-dip process. Threads manufactured in compliance with ANSI/ASME B1.20.1.

Galvanized nipples are a standard component in field-assembled pipe systems, offering a cost-effective and time-tested method of joining threaded pipe sections. When applied correctly with compatible fittings, this 1" galvanized nipple ensures durable, serviceable connections across a wide range of installations.
