Parker 139HB-6-4 Brass Elbow Hose Fitting 1/4 Nptf X 3/8 Id

Product Description

The PARKER 139HB-6-4 is a brass barbed hose fitting in a 90-degree elbow configuration, designed to connect a 3/8 inch inside diameter flexible hose to a 1/4 inch male NPTF threaded port. The brass body provides corrosion resistance suitable for fluid transfer applications in plumbing, HVAC, and light industrial systems. The hose barb end measures 0.415 inches in diameter, delivering a secure mechanical grip on compatible hose. The fitting is rated for use between -40 degrees F and 160 degrees F, making it appropriate for a range of liquid and low-pressure fluid service applications. Installation requires no special tooling beyond a wrench for the threaded end.

This fitting is used in residential and light commercial applications where a direction change is needed between a barbed hose connection and a threaded port. Common install scenarios include condensate drain lines, water supply connections, and fluid transfer assemblies where a 90-degree transition from a threaded component to flexible hose is required. The NPTF thread form provides a pressure-tight mechanical seal on compatible fittings without relying solely on thread sealant.

Key Features

• Elbow configuration provides a 90-degree transition between hose and threaded port
• 1/4 inch male NPTF threaded end for pressure-tight mechanical seal
• 3/8 inch ID hose barb end with 0.415 inch barb diameter for secure hose retention
• Brass construction resists corrosion in water and fluid service
• Rated from -40 degrees F to 160 degrees F for broad temperature compatibility
• Threaded connection type for straightforward installation and removal

Compatibility

Designed for use with 3/8 inch inside diameter flexible hose and 1/4 inch NPTF threaded ports in plumbing, HVAC, and light industrial fluid transfer applications.

Installation Notes

Installation should be performed by a qualified plumber or HVAC technician following applicable IPC and local plumbing codes. Shut off and depressurize the fluid system before installation or removal. Apply thread sealant tape or compound to the NPTF male threads as appropriate for the service fluid. Secure the hose barb end with a hose clamp rated for the operating pressure of the system.
