Neptonics Stainless Steel Floatline Plug

Overview

The Neptonics Stainless Steel Floatline Plug is a terminal fitting for building custom spearfishing floatlines. Machined from solid stainless steel, it fits tubing with a 1/4-inch inside diameter and provides a welded attachment ring for connecting floatline hardware.

Design and Function

The plug fits into the end of the floatline tubing, creating a metal termination point for the assembly. Its welded stainless steel ring provides a connection point for external rigging hardware, while the solid machined construction eliminates the need to assemble or weld the fitting before installation.

Floatline Assembly

Building a complete floatline also requires compatible tubing, an internal cord core, and a floatline finishing kit. The core should be approximately 5–10 feet longer than the intended finished floatline to allow for assembly and termination. UV-resistant tubing is recommended for prolonged outdoor use.

Each plug is sold individually. Select the required quantity based on the number of floatline ends being assembled.
