Black Iron Nipples

(194 products)

Our enormous stock of black malleable iron fittings includes a huge number of nipples. Nipples do the important job of connecting two fittings that are close to each other. Nipples come pre-cut and pre-threaded, unlike black iron pipe, which must be cut and threaded for each joint. This makes black iron nipples an extremely convenient and time-saving piece of hardware. The best thing about them is that they are low cost, with many of our nipple fittings costing under $1! Browse and select from our impressive stock of black malleable iron nipples below.
