Got a busted nipple fitting on a grease line and tryin to figure out if this one'll do the job as a swap-in. Both ends 1/4-18 NPTF male?

Question by: Frank A on Nov 14, 2025, 9:42 PM

both ends are 1/4-18 NPTF male, so if your existing fitting matches that thread spec on both sides, this long nipple should drop right in as a replacement. Brass construction with Dura-Kote plating means it holds up better than a plain brass fitting would in a corrosive environment, which matters on grease lines that see a lot of grime and moisture.
