Pro-source 3712601275PRO Automatic Drop Leg Drain 1/2 in

Product Description

The PRO-SOURCE 3712601275PRO is an automatic drop leg drain designed for use in compressed air systems. It automatically expels accumulated moisture and condensate from the low points of a compressed air distribution line, helping maintain air quality and protecting downstream equipment from water contamination. Measuring 6.5 inches high and 2.75 inches wide, it is sized for installation on 1/2 inch pipe drop legs. At 1.85 pounds, the unit is compact and practical for a range of system configurations. Installation is typically performed by a licensed pipefitter, HVAC technician, or industrial maintenance professional.

This drain is suited for residential, commercial, and light industrial compressed air systems where moisture buildup in distribution piping is a concern. It is installed at the low points of compressed air drop legs to collect and automatically discharge liquid condensate without requiring manual intervention. Typical applications include compressor room distribution headers, tool drops, and air-operated equipment supply lines where consistent air quality is required for reliable equipment operation.

Installation Notes

Installation should be performed by a qualified pipefitter or mechanical contractor familiar with compressed air system piping. Depressurize and isolate the affected section of the compressed air system completely before removing any existing drain or fitting. Follow applicable plumbing and mechanical codes for compressed air piping, including relevant ASME and local jurisdiction requirements. Do not overtighten threaded pipe connections; use appropriate thread sealant rated for compressed air service.
