Schedule 40 black nipple for plumbing systems

This 2-1/2 inch by 7 inch Schedule 40 black nipple connects threaded pipe sections in plumbing installations. It suits contractors and maintenance teams joining steel pipe runs carrying water, gas or oil. The fitting is new and supplied by Legend Valve under part reference 355-191E. Buyers needing a different diameter, length or material should select another fitting.

Threaded steel construction handles pressure

The Schedule 40 wall thickness provides the strength required for standard-pressure service in residential and commercial systems. Black steel withstands the temperatures found in typical hot-water and steam lines without deformation. No special tools beyond standard pipe wrenches are needed for assembly. Installers should follow local codes for joint compound or tape on the tapered threads.

Proposition 65 warning applies to this fitting

California Proposition 65 notices state that this product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. The warning is a regulatory requirement for items sold into California. Buyers who must avoid listed substances should verify suitability before purchase. The notice does not indicate a defect in the nipple itself.

Questions about this item

How do I install the 2-1/2" Schedule 40 black nipple without damaging the threads?

Apply pipe thread sealant or tape to the male threads, hand-tighten into the female fitting, then use a pipe wrench for one to two additional turns. Over-tightening cracks the fitting or strips the threads.

What maintenance or replacement will this Schedule 40 black nipple need over time?

Inspect periodically for external rust, mineral scale, or leakage at the joints. Replace the nipple if corrosion penetrates the wall or if threads become damaged during service.

What is the first limit that appears when this Schedule 40 black nipple is under sustained pressure and heat?

The Schedule 40 wall thickness sets the maximum continuous working pressure at the system operating temperature. Exceeding that pressure rating causes deformation or rupture before other factors.
