Nipples

Trenton Pipe Nipple Company is one of the largest, oldest, and most respected manufacturers of Red Brass nipples. In addition to a large inventory of a wide range of sizes, custom lengths are generally made and shipped within hours, not weeks as done by others.

Specifications
All Trenton Brass and Chrome Plated Brass nipples are manufactured to the exacting standards of ASTM B-687 (Rev. 96).

Standard nipple threads are NPT National (American) Pipe Taper threads. In addition to the standard NPT threads, nipples are available in a variety of thread forms. See NPT Thread Data.

Sizes / Diameters
Diameters from 1/8” thru 6” in Regular (Schedule 40) and 1/8” thru 4” in Extra Strong (Schedule 80).

Lengths
Pipe and therefore nipples are available in virtually ANY length, but most pipe is stocked in 12 ft lengths.

Tempers
All are available in General Purpose Drawn temper (H58 temper) and most are also available in Annealed (O61) temper. (Unless specified otherwise, H-58 temper will be supplied.)

In addition to providing standard sizes (close to 12”), Trenton stocks long lengths and specializes in making odd length nipples as required. In most cases, special length nipples are shipped in the same expeditious time frame as stock items. There is no one who can satisfy the customer’s needs for special nipples as quickly as Trenton!
