Zoro Select

Zoro Select ZUSA-PF-7891 Male Tee 304 Stainless 1/4 in NPT

SKU CH-9B5T-020GW

A 304 stainless steel male tee with 1/4 in NPT threads on all three sides, rated to 7500 psi for air, gas, oil, water and steam

  • 304 stainless steel resists corrosion in harsh media
  • Male NPT threads on three ports simplify inline branching
  • 7,500 psi rating handles high-pressure instrument lines
  • Low-lead compliant for potable water systems
  • ANSI B31.1 conformance supports code-driven installations

Industrial Pipe Fitting

The Zoro Select ZUSA-PF-7891 is a male tee fitting built from 304 stainless steel for instrumentation and control systems. It connects, redirects or terminates small-bore tubing carrying air, natural gas, oil, potable water or steam. The component meets low-lead requirements for potable water service. It conforms to ANSI B31.1 for power piping applications.

Threaded Connections

Each of the three ports carries male NPT threads at 1/4 inch nominal size with 18 threads per inch. The all-male layout lets the fitting join three female-threaded components directly without extra adapters. Stainless steel construction resists corrosion in harsh fluid environments. Silver colour provides quick visual identification in the field.

Pressure Rating

Maximum operating pressure is rated at 7500 psi, defining the safe limit for system design. This single figure determines whether the fitting suits the intended service. Builders needing a different pressure class or a female-threaded port must select another part.

Questions about this item

What does the 1/4 in NPT interface with 18 threads per inch cap in practice?

The 1/4 in NPT male threads on all three ports seal at up to 7,500 psi for air, natural gas, oil, potable water and steam service.

What clearance and thread engagement does the 304 stainless male tee need to fit?

Each of the three 1/4 in NPT male ends requires a matching female NPT port with full 18 TPI engagement; the compact tee body fits standard instrumentation panels.

How is the ZUSA-PF-7891 installed, and what step is often missed?

Apply PTFE tape or pipe dope to the male NPT threads, tighten to the ANSI B31.1 make-up torque, and pressure-test to 7,500 psi — skipping the thread sealant causes leaks.
