How to Assemble Plugs (Fittings)
In this step-by-step video, you will learn how to assemble Swagelok® plugs, which are used to close and seal unused ports in fluid systems. Plugs play an important role in maintaining system integrity by helping contain system pressure, preventing leakage, and allowing for future system modifications or expansion. Available in a variety of sizes, materials, and configurations, they are commonly used across industrial, laboratory, and process applications where reliable fluid system performance is essential. Understanding the proper selection and installation of plugs can help support safe, efficient operation and long-term system reliability. This video covers key assembly practices and installation considerations, and for additional guidance, refer to the Swagelok Tube Fitter's Manual.

Welcome to this Swagelok how‑to video.
Here’s what you’ll need to perform the procedure shown in this brief video: two open‑end wrenches, or one open‑end wrench and a vise.
Swagelok plugs can be used to block a Swagelok fitting port when desired.
Remove the nut and ferrules from the Swagelok tube fitting.
Turn the plug onto the fitting so that it is finger‑tight.
While holding the fitting body steady, tighten the plug one‑quarter turn.
For 1/16‑, 1/8‑, and 3/16‑inch sizes, and 2, 3, and 4 mm sizes, tighten the plug one‑eighth turn.
Swagelok plugs can be disassembled and reassembled many times.
Make subsequent connections by slightly tightening with a wrench after rotating the nut to finger‑tight.
Always depressurize the system before disassembling a Swagelok plug.
Do not mix or interchange parts with those of other manufacturers.
