The Blue Aluminum Elbow for Compressed Air Systems provides a corrosion-resistant, low-pressure-drop solution for directional changes in compressed air piping networks. Available in 90° and 45° configurations with sizes ranging from 1/2” to 6”, these elbows are constructed from high-grade 3003 aluminum alloy with a proprietary blue electrophoretic coating that enhances both durability and system visibility . Rated for operating pressures up to 232 psi (16 bar) and temperatures from -4°F to 176°F (-20°C to 80°C), they feature precision-machined ends for leak-free connection to compatible aluminum pipes and fittings . The elbows’ smooth internal geometry minimizes pressure loss, making them ideal for energy-efficient compressed air distribution in industrial and commercial facilities.
The dual-layer coating system provides 300% better UV resistance than uncoated aluminum and exceeds 1,000 hours of salt spray testing per ASTM B117, preventing corrosion in humid environments . The distinctive blue color also enables quick identification of compressed air lines.
With a wall thickness of 2.5mm to 8mm (depending on size) and internal surface roughness of Ra < 0.8 μm, these elbows produce only 3-5% pressure drop at maximum flow, significantly less than galvanized steel elbows .
Weighing 60% less than equivalent steel elbows, the aluminum design reduces structural support requirements and simplifies installation, cutting labor costs by approximately 30% compared to metal alternatives .
Precision-machined ends with dimensional tolerances of ±0.05mm ensure secure mating with push-to-connect, compression, and welded fittings commonly used in aluminum compressed air systems.
These blue aluminum elbows are ideal for:
• Automotive Assembly Plants: Direction changes in robotic tool air lines.
• Food Processing Facilities: Corrosion-free compressed air distribution in washdown areas.
• Warehouse Operations: Efficient airflow in overhead compressed air networks.
• Pharmaceutical Manufacturing: Clean air systems requiring non-contaminating components.
• Construction Sites: Temporary and permanent air lines in outdoor environments.
The 3003 aluminum alloy is non-toxic and corrosion-resistant, while the blue coating is free from heavy metals, meeting FDA 21 CFR 175.300 requirements for food contact surfaces .
Yes, when paired with transition fittings, they connect seamlessly to steel piping, allowing gradual system upgrades to aluminum.
To maintain efficient airflow, limit to 4 elbows per 50-foot run. More elbows may require pressure compensation to maintain end-use pressure.
