00:00:01 for over 65 years li plug expansion plugs have been the most reliable and economical method of sealing fluid passageways with more than 100 million plugs installed in aircraft missiles spacecraft and other critical hydraulic and pneumatic applications the Li plug includes two components the Li plug and a tapered pin which is driven into the plug the plug is placed into a reamed
00:00:30 counter bore in your manifold the tapered pin is then driven into the plug until the ends of the pin and plug are flush with each other Li plug installation is based on the Li locking end principle of controlled expansion used throughout the Li insert product line the outside diameter of the plug has many lands and grooves as the pin is driven into the plug controlled
00:00:57 expansion causes the lands and grooves of the plug to bite into the surrounding bore material forming independent seals and retaining rings this provides a positive reliable leak and trouble-free seal for both liquids and gases this unique design leads to a number of li plug advantages the tapered pin provides evenly distributed force along the length of the plug resulting in
