A Kleinn hex male nipple adapter with 1/4" male NPT threads on both ends, intended for joining or extending 1/4" NPT air lines and fittings. The small, threaded adapter lets installers connect components with matching male ports or bridge minor thread size changes cleanly, helping to complete plumbing runs on air tanks, compressors and accessories where identical male NPT connections are required.
