Description This is a 15' hose with a 3/8" inside diameter and solid brass 1/4" Male NPT threaded ends on each side. Solid brass end connectors never corrode and seal better against leaking than aluminum, steel, or zinc. This short hose is ideal for connecting supply lines, hose reels, compressors, and other system components. Its flexibility prevents vibrations from moving parts from traveling through the system and loosening connections or causing leaks. Specifications .
