Question by: Warren M on May 26, 2025, 4:55 PM
got a line with 1/2-14 female npt on it now, and i need to step down to 3/8-18 male npt. is this the straight adapter for that?
Answer by: Customer Support on May 28, 2025, 1:42 PM
For that kind of step down, it matches a 1/2-14 female NPTF on one end and a 3/8-18 male NPTF on the other, in a straight pipe to pipe brass adapter.
Question by: Billy W on Sep 5, 2025, 6:19 PM
brass or not, will this adapter hold up in a hydraulic system runnin grease lines without leaking all over the place?
Answer by: Customer Support on Sep 7, 2025, 8:38 AM
Brass construction on this fitting handles grease system applications without issue. The threads are NPT on both ends, which taper to form a mechanical seal when properly installed. No thread sealant comes pre-applied, so you'll want to use an appropriate sealant or tape on the threads before running it in a pressurized grease line. That absence of factory sealant is actually a plus for sensitive systems where contamination matters.
