Parker 1/8 Kmmoo-s Female Cross 1/8 Inch Fnptf Fitting

Product Description

The PARKER 1/8 KMMOO-S is a female cross pipe fitting designed for industrial fluid and pneumatic systems. It connects four female-threaded lines at a single junction, allowing flow distribution or branching in a plumbing or pneumatic circuit. Constructed from zinc-plated steel, the fitting delivers a pressure rating of 5000 psi, making it well-suited for demanding service environments. The FNPTF (Female National Pipe Taper Fuel) thread form creates a pressure-tight mechanical connection without relying solely on thread sealant. Plumbers, pipefitters, and industrial maintenance technicians are the typical installers of this type of fitting.

This fitting is used in industrial pipe assemblies where four lines must converge at a single point using 1/8 inch female NPT-style connections. Common applications include compressed air distribution, hydraulic instrumentation lines, fuel system plumbing, and general industrial fluid handling. Its compact 1/8 inch thread size makes it a common choice for instrument-branch and pilot-line configurations in both shop fabrication and field maintenance work.

Key Features

• Four-way female cross configuration for multi-line fluid or pneumatic distribution
• 5000 psi pressure rating for high-pressure industrial service
• FNPTF thread form provides a reliable, pressure-tight connection
• Zinc-plated steel construction resists corrosion in typical shop and industrial environments
• 1/8 inch female thread size fits standard NPT-compatible ports and fittings

Compatibility

Designed as an OEM-style replacement and standard-service fitting for industrial pipe systems using 1/8 inch FNPTF female thread connections.

Installation Notes

Installation should be performed by a qualified pipefitter or plumber following applicable codes such as the IPC or relevant industrial piping standards. Depressurize and isolate the system completely before removing or installing any fitting. Apply thread sealant tape or compound appropriate for the service fluid to all male threads mating into this fitting. Do not overtighten, as excessive torque can crack zinc-plated fittings or distort threads.
