Product Questions & Answers

what's the difference between a black nipple and a galvanized one, and would this 1/8 inch size work for a low-pressure air line?

Question by: Neil K on Feb 12, 2026, 10:27 AM

Black pipe fittings skip the zinc coating that galvanized ones carry, which makes them a common pick for gas lines, oil lines, and similar applications where that coating isn't needed or wanted. For a low-pressure air line at 1/8 inch, this nipple can get the job done depending on your setup, though the 3-inch length is worth confirming against your spacing before you order.

i keep seein “1/8 x 3” on these nipples, what’s that actually mean?

Question by: Kent R on Dec 26, 2025, 6:00 PM

It’s a black nipple with a 1/8 size and a 3 inch length, typically used as a short threaded connector between two fittings or ports.
