3/4 inch x 1-1/2 inch Brass Nipple

3/4" x 1-1/2" Brass Nipple – Threaded Fitting for Precision Transitions

The 3/4" x 1-1/2" brass nipple is a precision-machined fitting designed for threaded pipe systems. Commonly used in water, air, and non-corrosive fluid applications, this component provides a reliable and pressure-rated connection between two female-threaded pipe segments.

Manufactured from lead-free brass, this fitting offers both mechanical strength and corrosion resistance, meeting performance standards required for potable water and general plumbing systems.

Advantages of Brass Construction

• ✅ Thread Consistency – Uniform threads support a leak-resistant seal and reduce the risk of cross-threading during installation.
• ✅ Lead-Free Alloy – Suitable for potable water systems, conforming to low-lead content regulations.
• ✅ Corrosion Resistance – Ideal for contact with water and non-reactive fluids; resists scale buildup and dezincification.
• ✅ Dimensional Accuracy – Fabricated to meet industry tolerance requirements for pipe fittings.
• ✅ High-Temperature and Pressure Capable – Maintains integrity under thermal stress and moderate system pressures.

Installation Considerations

This fitting is intended for use in threaded piping systems. Apply thread sealant or PTFE tape to the male threads before installation to ensure a leak-tight seal. Use a wrench to apply consistent torque, avoiding overtightening that may damage threads. Verify compatibility with system materials and fluids.

Common Use Cases

Frequently installed in domestic water systems, mechanical room piping, and compressed air lines. Also utilized in retrofit and service applications where precise pipe length and compatibility with existing brass or copper components are required.

Material Performance

Brass is selected for its machinability, resistance to internal corrosion, and suitability for use with potable water and inert gases. Lead-free brass formulations comply with current plumbing code requirements in regulated jurisdictions.
