1/4 inch x 3 inch Brass Nipple

1/4" x 3" Brass Pipe Nipple – Machined for Precision and Long-Term Reliability

The 1/4 inch x 3 inch Brass Pipe Nipple is a precision-machined fitting engineered for use in a variety of plumbing, hydraulic, and pneumatic systems. Manufactured from lead-free brass, this nipple provides strong resistance to corrosion, high pressures, and thermal expansion—making it suitable for demanding commercial and industrial applications.

Commonly used for joining two female-threaded components, this nipple delivers high thread integrity and secure engagement, minimizing the risk of leakage in both water and gas systems. Its uniform wall thickness and seamless interior bore ensure minimal pressure loss and turbulence in flow-sensitive applications.

Key Performance Features

• ✅ Material: Lead-free brass per ASTM B62 and NSF/ANSI 372 compliance for potable water applications
• ✅ Thread Type: NPT (National Pipe Thread), male x male per ANSI/ASME B1.20.1
• ✅ Pressure Rating: Suitable for use in systems operating up to 1,200 PSI for air and 150 PSI for saturated steam
• ✅ Corrosion Resistance: Withstands oxidizing and non-oxidizing environments; ideal for water, gas, oil, and low-concentration chemical flow
• ✅ Versatile Fit: Compatible with brass, bronze, copper, and galvanized components in multi-material systems

Typical Applications

The 1/4" x 3" brass nipple is widely used in:

• • Commercial and residential water supply systems
• • Low-pressure natural gas and propane systems
• • HVAC and hydronic heating loops
• • Instrumentation and control tubing interfaces
• • Compressed air and vacuum line configurations

Installation Guidelines

Installation should follow standard practices for threaded pipe joints. Apply PTFE tape or pipe thread compound to male threads before tightening to ensure a leak-resistant seal. Torque should be applied evenly with a pipe wrench to avoid thread deformation or galling. Always verify compatibility with the piping material and fluid type before installation.

Did You Know?

Brass is a preferred material for threaded nipples due to its workability, corrosion resistance, and non-sparking properties—making it a critical component in both plumbing and industrial fluid handling systems.

The 1/4" x 3" Brass Pipe Nipple meets performance expectations for threaded piping systems that demand reliable, long-term sealing and mechanical durability. Ideal for professional-grade construction and retrofit environments where precision and longevity matter.
