Aeroquip Fitting, Plug, 14 in NPT, Allen Head, Aluminum, Blue Anodized, Pair

The Aeroquip FCM3686 Blue Anodized Aluminum 14 NPT Allen Head Pipe Plugs have garnered mixed reviews from users, revealing a blend of appreciation and frustration. Customers are attracted to this product primarily due to its brand reputation and fair pricing, especially since they are often difficult to locate in traditional aviation supply stores. Many users appreciate the plugs for their aesthetic appeal, notably the vibrant blue color, and confirm that they do not exhibit markings suggesting they are produced in China. However, several users expressed dissatisfaction with the design, particularly noting that the tapered NPT threading does not seem to align with the plugs, which are perceived as having straight sides. This misalignment has led some customers to run the plugs through a taper die before proper installation, indicating potential quality control issues. Additionally, there have been reports of the plugs stripping easily when installed, particularly if not tightened carefully. Customers have raised concerns regarding the accuracy of sizing, with experiences of receiving plugs labeled incorrectly. Overall, while many users find the Aeroquip plugs functional for specific applications and appreciate their quality and finish, price and potential design flaws have left some customers feeling that this product does not fully meet their expectations. **
