Product Identity
Zoro Select 1MMZ4 is a forged-steel cross fitting with four female NPT ports sized at 3/4 inch. The black oxide finish and Class 3000 rating suit high-pressure piping systems. Plumbing professionals and industrial maintenance teams use it to branch fluid lines in hydraulic or compressed-air circuits.
Who It Suits And Who It Does Not
Installers needing a four-way intersection for 3/4 inch NPT pipe threads will find this cross matches the thread standard and pressure class. Buyers who require a different thread type, a larger or smaller port size, or a lower pressure rating should look at alternative fittings that meet those specific needs.
Deciding Specification
The Class 3000 pressure rating is the single figure that determines whether this cross can handle the system’s maximum working pressure. Verify that your application’s design pressure falls within this class before selecting the fitting.

Questions about this item
What pressure does the Class 3000 rating cap the cross at?
Class 3000 forged steel is rated for 3000 psi working pressure, so this cross handles up to 3000 psi in standard service.
What thread size and type does each port use for mounting?
Every port is 3/4 inch female NPT, giving four identical FNPT connections for pipe nipples or fittings.
How do I seal the NPT threads without causing leaks?
Apply PTFE tape or pipe dope on the male threads only, tighten two turns past hand-tight, and avoid over-torquing the forged steel body.
