Permatex® High Strength Removable Orange Threadlocker is a one-of-a-kind anaerobic formula that combines the strength of Permatex® Red Threadlocker with the removability of Permatex® Blue Threadlocker. Permatex® Orange Threadlocker provides high strength for heavy-duty applications, but unlike Red Threadlocker, can be removed with hand tools and does not require heating to achieve removal.
