Our Discount Hydraulic Hose Thread Identification Kit is a perfect addition to your shop, garage, workbench, or anywhere else you wind up working with threaded fittings! This ID-KIT includes 31 heat-treated aluminum gauges that are individually stamped (worry no more about putting them back correctly!) to help you identify British Parallel and Metric Threads. The rugged, lockable carrying case ensures that your gauges will be there when you need them most. Also included is our handy Thread ID Guide booklet ($5.00 value!) that will help you figure out any remaining thread questions.
Included in the ID-KIT are the following items.
- M8x1.0 - M52x2.0 metric thread gauges
- 1/8-28 BSPP to 2-11 BSPP thread gauges
- Hard Carrying Case
- How to Identify Fluid Ports and Connectors Guide Book

Popular Questions
JIC (Joint Industry Council) fittings can be identified by their 37-degree flare seating surface, which differentiates them from other types like the 45-degree flare fittings. Additionally, they are typically marked with the JIC designation or size, and the threads can be measured to match standard JIC thread sizes, which conform to SAE J514 specifications.
Hydraulic fittings are components used to connect hoses, pipes, and tubes in a hydraulic system, ensuring a secure and leak-free flow of hydraulic fluid. They come in various types, such as threaded, crimped, and flanged, and are made from materials like steel, brass, or stainless steel to withstand high pressures and corrosive environments. Proper selection and installation of hydraulic fittings are crucial for maintaining system integrity and performance.
Thread identification refers to the unique identifier assigned to each thread within a process by the operating system. This identifier, often called a thread ID or TID, allows the system and developers to manage, track, and reference individual threads separately, ensuring proper execution and resource allocation.
To read a metric thread callout, you typically see a format like M8 x 1.25, where "M" indicates a metric thread, "8" represents the nominal diameter in millimeters, and "1.25" is the pitch, or the distance between threads, in millimeters. Additional information such as thread tolerance class may follow, for example, M8 x 1.25 - 6g, where "6g" indicates the tolerance grade.
Yes, NPT (National Pipe Thread) threads have a tapered angle of 60 degrees, while BSP (British Standard Pipe) threads have a 55-degree angle and can be either parallel or tapered. You can identify them by measuring the thread angle with a gauge and checking the thread pitch and shape; NPT threads will have a slight taper, whereas BSP threads are often parallel (BSPP) or have a gentler taper (BSPT).
To identify the type of thread, examine its physical characteristics such as pitch, diameter, and thread angle, and compare them to standardized thread profiles like ISO metric, UNC/UNF, or BSP. Additionally, using thread gauges or a thread identification tool can provide precise measurements to match the thread to known standards.
In hydraulics, the most commonly used threads are National Pipe Tapered (NPT), British Standard Pipe (BSP), and metric threads. These threads ensure a secure, leak-proof connection in hydraulic systems, which is essential for maintaining system pressure and performance. The choice of thread type often depends on regional standards and specific application requirements.
