3/8 inch x 1/4 inch Brass Reducing Adapter Lead-Free Female x OD

Optimize Transitions with the 3/8 Inch x 1/4 Inch Lead-Free Brass Reducing Adapter

The 3/8 inch x 1/4 inch Brass Reducing Adapter is a precision-machined component designed for secure, threaded transitions between dissimilar pipe sizes in plumbing and mechanical systems. Fabricated from lead-free brass, this fitting supports potable water applications and complies with applicable codes for safety and performance.

Performance-Driven Features

• Threaded Male-to-Female Connection – Engineered for compatibility with standard NPT threads, allowing tight engagement with minimal thread deformation.
• Lead-Free Certification – Meets or exceeds NSF/ANSI 61-G and 372 requirements for use in systems delivering potable water.
• Corrosion Resistance – Brass composition resists dezincification, pitting, and scale buildup in a range of environmental conditions.
• Pressure Rating – Suitable for working pressures commonly found in residential and light commercial water systems.
• Dimensional Accuracy – Manufactured to strict tolerances using automated CNC processes to ensure repeatable, leak-resistant installs.

Specifications

• Material: Lead-Free Brass (DZR-rated)
• End Connections: 3/8 inch Male NPT x 1/4 inch Female NPT
• Application: Potable water, air, and non-corrosive fluid systems
• Temperature Range: Up to 200°F (dependent on sealing method)
• Pressure Rating: Typically up to 200 psi for water systems

Installation Guidelines

Apply PTFE thread sealant or approved pipe joint compound to male threads prior to installation. Avoid over-torquing, which can compromise sealing surfaces or crack mating components. Use calibrated hand tools to ensure torque remains within manufacturer-recommended thresholds.

Common Applications

This reducing adapter is widely used in plumbing assemblies requiring reliable conversion between 3/8 inch and 1/4 inch threaded pipe, tubing, or fittings. It is typically implemented in appliance hookups, fixture installations, and transition points in hydronic and potable water systems.

Regulatory Insight

Brass fittings labeled as inchlead-free inch must contain a weighted average of no more than 0.25% lead across wetted surfaces per Safe Drinking Water Act (SDWA) guidelines adopted nationwide.

Engineered for performance and compliance, the 3/8 inch x 1/4 inch Brass Reducing Adapter delivers durable and secure transitions under demanding service conditions—ideal for contractors requiring consistent, code-approved solutions in water and mechanical systems.
