1/4 inch ID Copper Long Radius 90° Elbow – Optimized for HVACR and Hydronic Flow Paths

The 1/4 inch inside diameter copper long-radius 90-degree elbow is designed for use in refrigeration, air conditioning, and low-pressure hydronic systems. Constructed from high-grade, seamless wrought copper per ASTM B75 or B280, this elbow allows smooth directional transitions with reduced pressure drop and minimized turbulence, compared to short-radius alternatives.

This fitting is suitable for use in both R-22 and R-410A systems and is annealed to facilitate brazing during field installations. Its long sweep provides better refrigerant flow characteristics and minimizes system noise, especially critical in precision HVACR applications.

Key Performance Features

• Material: Wrought copper, ASTM B280 compliant
• Nominal Size: 1/4 inch inside diameter (tube size)
• Bend Radius: Long-radius design for optimized flow with minimal friction loss
• End Type: Smooth tubing ends for brazed (sweat) connections
• Working Pressure: Rated for up to 700 PSI (with appropriate joint integrity and wall thickness)

Application Scope

This copper elbow is commonly used in:

• Refrigerant line sets for split-system and packaged HVAC units
• Chilled water piping in low-temperature hydronic systems
• Condenser and evaporator coil assemblies
• Dehumidification and heat pump loops

Installation Guidance

To ensure a reliable, pressure-rated joint, use nitrogen purging during brazing to prevent oxidation and scale buildup. Clean all mating surfaces thoroughly and select a compatible brazing alloy. Do not overheat to avoid compromising the temper of the elbow. Always follow ASHRAE and UPC/IPC code requirements for refrigerant or water-carrying copper joints.

Code Compliance Note

This product is lead-free and meets federal Safe Drinking Water Act (SDWA) guidelines, as well as NSF/ANSI 61 requirements for potable water if used in domestic systems. It is also UL listed for refrigerant applications where applicable.

Engineered for contractors who demand performance, durability, and code compliance, the 1/4 inch ID copper long-radius 90° elbow provides smooth directional flow and robust brazed joint capability—ensuring reduced vibration, optimized line layout, and long-term reliability in HVACR piping systems.
