Eaton 1075X4 Barbed Tube Fitting 1/8 in Thread

Product Description

The EATON 1075X4 is a barbed tube fitting designed for low-pressure fluid and pneumatic line connections in plumbing, HVAC, and light industrial applications. The fitting features a 1/8 inch thread size and accepts tubing with a 1/4 inch outer diameter. The barbed design creates a secure mechanical grip on flexible tubing without additional fittings or clamps in many installations. At 0.056 pounds, it is a compact, lightweight component suited for tight-space installations. Plumbers, HVAC technicians, and general mechanical contractors are the typical installers of this type of fitting.

This barbed tube fitting is appropriate for residential and light commercial plumbing and HVAC systems where 1/4 inch OD flexible tubing must connect to a threaded port with a 1/8 inch thread. Common use cases include condensate drain lines, refrigerant oil lines, pneumatic control tubing, and similar low-pressure fluid transfer applications. Its small form factor makes it especially useful in confined equipment compartments and panel installations.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Shut off fluid or air supply pressure to the line before disconnecting or installing any fitting. Apply thread sealant or PTFE tape to the threaded end in accordance with applicable IPC or IFGC requirements. Ensure tubing is fully seated past the barb before pressurizing the line to confirm a leak-free connection.
