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

3/8 inch x 1/4 inch Lead-Free Brass Reducing Adapter – Male NPT x Compression

This 3/8 inch male NPT x 1/4 inch OD compression reducing adapter is engineered for system transitions between threaded and compression-type connections. Constructed from lead-free brass, it provides corrosion-resistant performance and compatibility with potable water applications where dimensional transitions are required in compact piping layouts.

Engineered for System Integrity

Specifying high-performance fittings reduces the likelihood of system failure, leakage, or non-compliance with plumbing codes. This reducer offers:

• ✅ Certified Lead-Free Composition Complies with ANSI and NSF standards for potable water system components.
• ✅ Thread and Compression Machining Threads meet NPT standards, and the compression end is precision-formed for consistent sealing on copper or plastic tubing.
• ✅ Compact Transition Profile Ideal for tight clearances, equipment panels, or retrofit scenarios where space efficiency is critical.
• ✅ High Tensile Strength Brass construction resists mechanical deformation and is suitable for indoor and covered outdoor installations.

Installation Guidelines

Threaded end should be sealed with approved PTFE tape or anaerobic thread sealant. The compression end requires correct ferrule seating and torque to prevent leaks. Compatible with copper and select plastic tubing. Use a two-wrench method to prevent over-rotation and protect system integrity during installation.

Technical Specifications

• Body Material: Lead-free brass
• Connection A: 3/8 inch Male NPT
• Connection B: 1/4 inch OD Compression
• System Rating: Suitable for potable water, low-pressure air, and inert gas applications

Functional Benefits

• ✅ Corrosion-Resistant Brass Maintains structural integrity in a variety of environmental conditions.
• ✅ Pressure-Tight Joint Formation Engineered contact surfaces reduce leak potential under standard operating conditions.
• ✅ Multi-System Compatibility Commonly used in water distribution, appliance hookups, HVAC, and instrumentation lines.

Typical Use Cases

Designed for use in retrofit or new installations requiring a reliable connection between male pipe threads and 1/4 inch compression lines. Often used in service valves, fixture tie-ins, supply risers, and other confined-space plumbing where reducer fittings are necessary for dimensional transitions.

Compliance Insight

As mandated by federal legislation and state plumbing codes, the use of lead-free brass components is required for any system supplying water for human consumption. This fitting meets those requirements while maintaining durability and mechanical performance.

Use the 3/8 inch x 1/4 inch lead-free brass reducing adapter to ensure durable, compliant, and pressure-capable transitions in fluid systems. Built to meet contractor expectations for reliability and installation efficiency in the field.
