4" NIBCO Double Elbow

In multi-stall vacuum plazas, conventional tight-angle plumbing fittings induce immense airflow resistance, restricting turbine intake capacity and degrading suction power at the guest hose drops. This specialized double elbow configuration provides a balanced, dual-directional transition branch that allows multiple trunk or drop lines to seamlessly integrate into a single 4-inch vacuum header line with minimal fluid friction. Molded from rugged black Acrylonitrile Butadiene Styrene (ABS), this non-pressure fitting boasts exceptional structural resistance to constant negative suction pressure, internal temperature variations, and the continuous scouring action of fine road gravel, sand, and debris moving through the lines.

Key features and benefits include:

• Optimized Vacuum Airflow Dynamics: Engineered as a high-capacity double branch junction to smoothly merge or divide heavy suction lines without choking system airflow.
• Industrial ABS Construction: Molded from premium black ABS plastic, providing superior impact resistance, anti-collapse rigidity under full vacuum loads, and unmatched internal abrasion protection against sharp debris.
• Full 4-Inch Hub Connections: Features three precision-molded 4" Hub openings (Hub x Hub x Hub) designed to slip over and solvent-weld directly onto standard 4-inch ABS pipes for a flush, airtight joint.
• Corrosion & Moisture Inert: Completely immune to backroom humidity, continuous dampness, and chemical overspray drift, ensuring it won't rot, rust, or pit over years of operational service.
• Saves Footprint Spatial Envelope: Replaces multiple cascading fittings with a single, structural multi-port junction, optimizing tight mechanical spacing on overhead racks or inside backroom vacuum collector pads.
