Please consider 1/4 Knurled Thumb Screw Tank Drain as an alternative.
1/4" male npt air compressor tank drain. This is a standard tank drain that will work with virtually all air compressors that have a 1/4" tank outlet. Always drain your tank to prevent water build up and rust.
Though this product has been around many years and "is the industry standard" we HIGHLY recommend choosing the DC14 Thumb-screw Tank Drain
