3/8 inch x 1/4 inch Brass Flared 90 Degree Reducing Elbow OD Flare x Male

3/8" x 1/4" Brass Flared 90° Reducing Elbow – Compression Elbow for Directional Tubing Transitions

The 3/8" x 1/4" Brass Flared 90 Degree Reducing Elbow is a precision-machined fitting used to connect two dissimilar outer diameter flared tubes at a 90° angle. Designed for use with soft metal tubing such as copper or aluminum, this elbow provides a mechanically sealed joint in gas, water, fuel oil, or air systems. It accommodates transitions between 3/8" OD and 1/4" OD tubing in compact system layouts requiring directional change and size reduction.

This flared fitting utilizes metal-to-metal contact at the flare faces, eliminating the need for solder or sealant at the joint. It is suitable for systems where vibration resistance and periodic disassembly may be required, including fuel lines, HVAC controls, and appliance connections.

Product Features

• ✅ Flared Compression Seal: 45° flare end connections create a tight, vibration-resistant seal without the need for additional sealants.
• ✅ Brass Body Construction: Machined from high-quality, corrosion-resistant brass for long service life in residential, commercial, and light industrial systems.
• ✅ Size Reduction: Connects 3/8" OD tube to 1/4" OD tube while facilitating a 90° direction change, useful in space-constrained assemblies.
• ✅ Field Serviceable: Easily removable and reinstallable, allowing access for system maintenance or reconfiguration.
• ✅ Standard Compliance: Typically conforms to SAE J512 and ASME B16.22 specifications for flare fittings.

Technical Specifications

• Connection Type: Flared (3/8" OD x 1/4" OD)
• Material: Forged or machined brass
• Bend Angle: 90 degrees
• Flare Angle: 45° (standard for SAE flare fittings)
• Working Pressure: Varies by application; typically 150–200 psi for gas and 1,200 psi max for hydraulic service (verify with tubing rating)

Installation Guidelines

• Use a 45° flaring tool to prepare tubing ends; ensure flare faces are clean and uniform.
• Do not apply tape or pipe dope to flare threads; sealing occurs at the flare surface.
• Torque fitting using proper flare nut wrenches to avoid over-compression and maintain seal integrity.

Application Scope

This reducing elbow is typically used in fuel systems, refrigeration lines, water service connections, and instrumentation tubing networks where space and directional constraints exist. It is also suitable for gas appliance hookups and compressor systems where both pressure resistance and reusability are required.

Material Note

Brass flare fittings provide thermal conductivity and mechanical strength, with resistance to water, non-oxidizing acids, and many petroleum products. Lead-free variants comply with NSF/ANSI 61 and 372 standards for potable water systems in jurisdictions with low-lead mandates.

The 3/8" x 1/4" Brass Flared 90 Degree Reducing Elbow delivers a secure, serviceable, and pressure-rated connection for transitions in tubing systems where reliable mechanical seals and directional routing are critical.
