Tapered plugs chillers and heat exchangers

Tapered plugs available from MLP

Tapered plugs are used to repair and stop leaks in condensers, chillers and heat exchangers. They are driven into tube ends with a soft faced hammer until seated and sealed tight eliminating future leaks. Welding is optional depending on your application. Select a plug where the middle diameter will approximately match your tubing ID. It is best not to drive the plug in flush when installing, but to leave 1/4″ of the length exposed. The photo reveals grooved finishes for a better gripping surface, but smooth plugs are available as well. A wide range of sizes are manufactured from 2” down to .25”. Materials shown in the photo are 360 brass, 316L stainless steel and titanium; however, we will manufacture to your specifications and provide material certifications to suit your application. We understand that quick deliveries are critical for field maintenance and we won’t let you down. Please contact us for all your tapered plug needs.

Utilizing our CNC Lathe

Here is another example of MLP utilizing our CNC lathe by using a 304 Stainless Steel flange. The original flange was reverse engineered by MLP for our customer. After the reverse engineering was completed, the part was produced by using our CNC lathe and our Haas CNC milling machine. MLP was not only able to reverse engineer, but also produce this precision product for our customer. This is another example of the high quality precision machine component services we provide for our customers. Proudly Made in USA by MLP!
