Brass air hose drain cock 1/4 NPT with handle, 13mm

These brass air hose drain cocks are fitted directly to air compressor tanks to remove accumulated moisture and oil. Supplied as a pair, each features a 1/4 NPT male thread and 13mm diameter for reliable connection and operation.

The handle-operated screw adjustment design makes installation and operation straightforward. The brass construction provides excellent corrosion resistance, ensuring long service life in low-noise air pumps, woodworking paint sprayers, and industrial compressors.

Each drain cock functions as a replacement for worn or damaged original valves on existing equipment. Before installation, depressurise the storage tank completely and drain any remaining air pressure. Once fitted and sealed, the valve controls oil and water removal easily through manual handle adjustment.

Brass resists rust and degradation far better than standard materials, making these valves a durable upgrade for any compressed air system requiring regular maintenance drainage.

To install, ensure your tank is depressurised, remove the old valve, and fit the new brass drain cock securely in its place.
