Overview

Details: This section provides a detailed introduction to the aluminum American Type Coupling and its compatible thread specifications (e.g., NST/NPT/NH/BST). This type of coupling features a unique Expansion Ring design, which utilizes an internal copper ring to securely fasten the coupling to the hose through expansion. This method offers a more robust and leak-proof connection compared to traditional wire-binding techniques. Specifications cover common sizes such as 65mm (2.5″NH), 50mm (2″NH), 40mm (1.5″NH), and 25mm (1″NH). The information is clearly presented in a table with an orange background and black text for easy reference.
