Parker 215PN-4 Close Nipple 1/4 Inch Mnptf Brass

Product Description

The PARKER 215PN-4 is a brass close nipple designed for industrial pipe assemblies requiring a short, threaded male-to-male connection. Threaded on both ends with 1/4 inch MNPTF (male national pipe tapered fuel) threads, this fitting measures 0.88 inches in overall length and handles working pressures up to 1,000 psi. It is rated for temperatures from -65 degrees F to 250 degrees F, making it suitable for a wide range of fluid and gas service applications. Plumbers, pipefitters, and industrial maintenance technicians install close nipples like this to join two female-threaded fittings with minimal spacing between them.

This close nipple is used in industrial piping systems, hydraulic lines, pneumatic circuits, and fuel delivery assemblies where a compact threaded connector is required. Its brass construction provides corrosion resistance in water, air, oil, and many fuel service environments. The MNPTF thread form creates a pressure-tight seal in tapered female port threads. Typical applications include manifold assemblies, instrumentation connections, and equipment panel fittings in both commercial and industrial settings.

Key Features

• 1/4 inch MNPTF threads on both ends for direct male-to-female pipe connections
• 1,000 psi maximum working pressure rating
• Operating temperature range of -65 degrees F to 250 degrees F
• 0.88 inch overall length for tight-clearance installations
• Brass construction for corrosion resistance in fuel, water, and air service
• Meets SAE J530 and SAE J531 standards

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial piping systems using 1/4 inch MNPTF threaded connections in hydraulic, pneumatic, fuel, and general fluid service applications.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters in accordance with applicable codes such as the IPC or IFGC depending on the service medium. Depressurize and isolate the line completely before removing or installing any pipe fittings. Apply an appropriate thread sealant or PTFE tape to the MNPTF threads to ensure a leak-free connection; do not overtighten, as brass fittings can crack under excessive torque. Verify that the mating female port threads are clean, undamaged, and of a compatible thread form before assembly.
