This comprehensive kit includes six durable plastic cards, each tailored to specific fitting types such as NPT, NPSM, ORFS, JIC, ORB, and SAE 45°. With features that allow for accurate measurement of both outer and inner diameters, along with a versatile tool for determining threads per inch (TPI) and fitting angles, this kit simplifies and enhances your measurement process. Encased in a sturdy blue vinyl bag, it's the ultimate portable solution for both on-site and in-shop applications. How to Use Identify the Shape Select the card that matches the shape of the fitting or adapter you need to identify. For fittings with angled surfaces, use the angle guides on the angle and thread gauge tool to determine the correct angle. Measure the Size After choosing the card that resembles the part, find the closest diameter by inserting your fitting or port into each hole until you find the perfect match. Determine the Thread Once you've identified the correct outside diameter, if the part is threaded, use the angle and thread gauge tool to accurately measure the thread size. Features Ability to Measure Inner and Outer Dimensions Outer Dimensions Inner Dimensions Both OD and ID Threads Portable and Organized Storage Every component of the kit is securely stored in a durable blue vinyl bag, ensuring that all tools are kept together and well-organized.
