Value Brand 461-070GR 1/4" MNPT x 7" Red Brass Pipe Nipple Sch 40

SKU CH-7SSY-7JKQX

Red brass pipe nipple with 1/4" MNPT threads on both ends, 7" overall length, Schedule 40 wall, rated 125 PSI from 20 to 400 °F

  • Red brass construction resists corrosion
  • Schedule 40 wall handles 125 PSI working pressure
  • Male NPT threads on both ends simplify installation
  • Rated for 20 to 400 °F service temperature
  • Meets ANSI B 1.20.1 and ASTM B687 standards

Product identity and intended use

This red brass pipe nipple measures 1/4 inch nominal size with a 7 inch overall length and male NPT threads on both ends. It suits plumbing installations that require a short, corrosion-resistant connector rated for 125 PSI and temperatures between 20 and 400 degrees Fahrenheit.

Upgrade path and when to switch

The fitting replaces worn or leaking threaded nipples in Schedule 40 systems where lead-free brass is preferred. The jump is worthwhile when existing galvanised or standard brass nipples show dezincification, thread damage or cannot meet ANSI B1.20.1 and ASTM B687 compliance.

Installation notes and common pitfalls

Thread sealant or tape must be applied to both male ends before tightening to the specified torque for Schedule 40 pipe. Over-tightening can split the red brass body, while under-tightening leaves a leak path; ensure the mating female threads are clean and undamaged.

Questions about this item

What thread size does the 1/4 inch MNPT nipple need to seal against?

The nipple uses 1/4 inch MNPT threads on both ends to ANSI B 1.20.1, so it mates with matching 1/4 inch FNPT fittings.

Which step do installers often miss when fitting the red brass nipple?

Applying thread sealant or tape to the MNPT threads before tightening is the step most often skipped, yet it is required for a leak-free joint.

When should the 7 inch Schedule 40 nipple be inspected or replaced?

Inspect the nipple whenever the system is opened; replace it if threads show galling, the red brass body is corroded, or pressure tests exceed 125 PSI at up to 400 Degrees F.
