How to Read an AN Fitting Size Chart
Understanding thread sizes‚ dimensions‚ and nominal vs. actual sizes is crucial. The chart provides detailed measurements to ensure proper fitting selection for hydraulic and pneumatic systems.
Understanding Thread Sizes and Dimensions
Thread sizes on an AN fitting chart are specified by their diameter and threads per inch (TPI)‚ ensuring compatibility with various hydraulic and pneumatic systems. The chart distinguishes between nominal and actual sizes‚ with nominal sizes based on standard references and actual sizes providing precise measurements. For instance‚ an AN fitting labeled as -4AN corresponds to a 1/4-inch nominal size‚ while the actual thread diameter and pitch are detailed for accurate mating. This differentiation is critical in engineering applications to prevent mismatches and ensure system integrity. Proper understanding allows for precise component selection‚ optimizing performance and reliability in high-pressure environments.
Interpreting Nominal and Actual Sizes
Interpreting nominal and actual sizes on an AN fitting chart is essential for accurate component selection. Nominal sizes‚ often represented by dash numbers (e.g.‚ -4AN)‚ serve as reference points‚ while actual sizes provide precise measurements. For instance‚ a -4AN fitting corresponds to a nominal 1/4-inch size but includes specific thread diameter and pitch dimensions. Actual sizes ensure compatibility‚ preventing mismatches in fluid systems. Engineers must distinguish between these to maintain system integrity. Clarity in size interpretation is critical for selecting and installing components correctly‚ ensuring optimal performance and reliability in hydraulic and pneumatic applications. Proper understanding of these measurements is vital for safe and efficient system operation.
AN Fitting Sizes: A Detailed Breakdown
AN fitting sizes range from -2AN to -32AN‚ providing a standardized system for fluid and gas systems. Each size specifies thread diameter‚ tube outer diameter‚ and length dimensions.
AN Fitting Sizes by Thread Size
AN fitting sizes are categorized by thread size‚ ranging from -2AN to -32AN‚ with each size representing specific thread diameter and pitch. The thread size determines the outer diameter of the fitting‚ ensuring compatibility with tubes or hoses. For example‚ a -4AN fitting has a thread diameter of 0.25 inches‚ while a -8AN fitting has a thread diameter of 0.50 inches. These sizes are standardized to ensure precise connections in fluid and gas systems‚ particularly in aerospace and high-performance applications. The thread size chart provides detailed measurements‚ including thread count and pitch‚ to help users select the correct fitting for their specific needs. This precision is critical for maintaining system integrity and performance in demanding environments.
AN Fitting Sizes by Nominal Pipe Size
AN fitting sizes by nominal pipe size are standardized measurements that correspond to specific diameters‚ ensuring compatibility in fluid and gas systems. Nominal pipe size refers to the diameter of the pipe‚ which is often different from the actual outer diameter. For example‚ a nominal pipe size of 1 inch may not exactly measure 1 inch in diameter. These sizes are crucial for selecting the correct AN fitting‚ as they ensure proper connections and prevent leaks or system failures. The size charts provide detailed dimensions for each nominal pipe size‚ making it easier for engineers and manufacturers to choose the right fitting. This standardization is essential for maintaining system integrity and performance in various applications‚ including aerospace and high-performance fluid systems. By adhering to these nominal pipe sizes‚ users can ensure reliability and optimal functionality in their systems.
AN Fitting Sizes by Tube Size
AN fitting sizes by tube size are designated to match specific tube outer diameters‚ ensuring secure connections in high-performance systems. Tube sizes are often indicated by dash numbers‚ which correspond to standard tube diameters. For example‚ a -3 tube size refers to a 3/16 inch outer diameter‚ while a -4 corresponds to 1/4 inch. These sizes are critical for maintaining proper fitment and system integrity. The AN fitting size chart provides detailed measurements for each tube size‚ including thread dimensions and overall lengths. By adhering to these standards‚ engineers and manufacturers can ensure compatibility and reliability in applications such as aerospace and industrial fluid systems. The chart serves as a vital reference for selecting the correct fitting‚ preventing leaks‚ and optimizing system performance. Proper tube size matching is essential for safety and efficiency in demanding environments.
