Eaton 1068X4 Barbed Tube Male Connector 1/8 in Nptf

Product Description

The EATON 1068X4 is a barbed tube male connector designed to join flexible tubing to a threaded port in fluid and pneumatic line applications. The fitting features a 1/8 inch NPTF male thread on one end and a barbed stem sized for tubing with a 0.12 inch inside diameter and 1/4 inch outside diameter on the other. Constructed from brass, it delivers reliable sealing and corrosion resistance in a wide range of low-pressure fluid handling systems. Plumbers, HVAC technicians, and industrial maintenance trades use this style of fitting to make secure, leak-resistant connections between rigid threaded ports and flexible tubing without additional tools beyond standard hand tightening.

This barbed male connector is suited for residential and light commercial applications where flexible tubing must terminate at a threaded port on a valve, manifold, pump, or equipment housing. Typical uses include condensate drain lines, water supply connections, and pneumatic control tubing in HVAC and plumbing systems. The NPTF thread form provides a dry-seal mechanical fit that reduces the need for additional thread sealant. Sold individually, this fitting is a straightforward drop-in component for service and new installation work.

Key Features

• 1/8 inch NPTF male thread for dry-seal connection to threaded ports
• Barbed stem fits tubing with 0.12 inch inside diameter and 1/4 inch outside diameter
• Brass construction for corrosion resistance and durability in fluid service
• Compact, lightweight design at 0.02 pounds for easy handling in tight spaces
• Sold as a single unit for targeted service replacement or new installation

Compatibility

Designed as an OEM-style replacement or service fitting for systems using 1/4 inch OD flexible tubing with a 1/8 inch NPTF threaded port connection in plumbing, HVAC, or pneumatic control applications.

Installation Notes

Installation is typically performed by licensed plumbers or HVAC technicians working on low-pressure fluid or pneumatic lines. Shut off the relevant fluid or air supply and relieve system pressure before removing or installing any fitting. NPTF threads are designed to seal on the thread form itself, but applying a compatible thread sealant tape is acceptable practice where system requirements call for it. Ensure the barbed stem is fully seated into the tubing and secure with an appropriate clamp if the application requires a positive retention method.
