1/4" Schedule 40 Black Steel Nipple Assortment

This 66-piece assortment supplies 1/4" MNPT x MNPT black welded steel nipples in a range of standard lengths. Each piece is manufactured to Schedule 40 wall thickness and meets ANSI/ASME B1.20.1, ASTM A53 Type E Grade A and ASTM A733 standards. Electric resistance weld construction provides consistent quality for plumbing and compressed air lines.

Replaces individual nipple purchases

Buying the kit eliminates the need to source separate lengths for each job, reducing downtime on maintenance and new installations. The jump is worth it when a facility regularly uses 1/4" Schedule 40 black pipe and wants a single organised supply covering close, short and medium lengths.

Suits maintenance techs and pipefitters

The assortment fits technicians who need immediate access to multiple 1/4" nipple lengths for repairs or fabrication. Builders requiring larger diameters, stainless material or grooved-end fittings should look at other product lines.

Questions about this item

What thread size do the 1/4 in Schedule 40 nipples need to mate with?

Each nipple has 1/4 in MNPT threads on both ends, so they require matching 1/4 in FNPT fittings or ports to seal properly.

How do I seal the tapered NPT threads on these steel nipples without cracking the joint?

Apply PTFE tape or pipe dope to the male threads only, then tighten one to two turns past hand-tight; over-torquing the tapered joint is the common error that splits fittings.

When should I replace a nipple from this 66-piece assortment?

Replace any piece that shows visible rust, thread deformation, or leakage at the joint; the black welded steel has no sacrificial coating, so corrosion is the primary wear indicator.
