SKU CH-97JW-G3P9J

Connects two 3/4-inch Schedule 40 pipes using compression fittings on both ends

  • 3/4-inch compression fit joins copper without soldering
  • Low-lead brass meets potable-water standards
  • Zinc-plated finish resists corrosion in damp locations
  • Rated for Schedule 40 pipe at 160 psi

3/4" Compression Brass Coupling

The Mueller 160-305NL is a compression coupling manufactured from low-lead brass with a zinc-plated finish. It is designed to join two sections of 3/4 inch pipe using compression connections on both ends. This fitting suits residential and commercial plumbing installations where a reliable, solder-free joint is required.

Fits Schedule 40 Pipe Without Soldering

The coupling accepts 3/4 inch female compression connections at each end and is rated for Schedule 40 pipe. No open flame or solder is needed, which frees up installation time and reduces fire risk in confined spaces. The low-lead brass construction meets drinking-water safety requirements for potable systems.

Questions about this item

What pressure limit appears first when the 3/4" compression brass coupling runs continuously at schedule 40 rating?

The fitting is rated for schedule 40 service, so the 160 psi working pressure of that schedule becomes the limiting factor under sustained use.

How much heat does the brass coupling generate during all-day water flow?

Brass conducts heat away from the fluid, so the coupling itself adds no measurable heat; the line temperature simply follows the water temperature.
