Take a look at where the threads are located. It simply serves as a way to distinguish between the two connections. Next, determine if the thread is tapered or parallel. Tapered threads become narrower as they extend outward while parallel threads remain the same diameter. Sometimes this characteristic can be determined through visual inspection, but if not a caliper can come in handy. Use the caliper to measure the first, fourth, and final full thread.
These threads create a seal through metal-to-metal wedging or slight deformation of the threads. Parallel threads will often require an o-ring or thread tape to ensure a tight seal. The next step in identifying your thread type is to determine the pitch size. While a ruler could be used to calculate the pitch size, a pitch gauge is highly recommended as pitch sizes can be very similar. Test a couple different sizes with a pitch gauge to find the best match.
Using the caliper again, measure the outside diameter on a male thread and inside diameter on a female thread. There will inevitably be small variations due to different manufacturers. The final step in identifying your thread type is to identify the thread type standard. Gather the information from the previous steps and compare it with the measurements in the tables below.
You can also download all this information in a convenient PDF file. Download the Thread Identification Guide. Note: Due to variations in manufacturing the thread diameter may not match exactly with the measurements below. This thread type is most commonly used in North America. When torqued the flanks of the threads compress against each other forming a leak-tight seal. However, it is still recommended to use PTFE tape or another sealant compound to guarantee a completely leak-tight seal.
It ensures an even more leak-free seal. But it is important to note that using these variants together diminishes their leak-free characteristics. NPT threads should be burr-free and lubricated using lubricating paste or tape. Doing so limits corrosion on the threads which otherwise can make future disassembly nearly impossible.
This is a standard thread type that has been adopted internationally for interconnecting and sealing pipe ends. BSPP refers to parallel or straight threads. Meanwhile, BSPT refers to tapered threads. Are you confused yet?
However, since the male PT thread does not have a degree flare, it will not mate with the BSPP female swivel with conical seat. Also, we recommended using thread sealant with PT threads to ensure a leak-free seal. This is a highly reliable and reusable thread type. While some thread types require the threads of the male and female end to crush together to form a seal, the O-Ring on this thread type prevents that.
Metric thread type is most common in Europe. It has a cylindrical inner and outer diameter precise in millimeters. The fine taper of metric tapered thread allows for the best possible force transmission. M22 x 1. These parts may or may not come standard with a Nickel Plating. Our Push-In Fittings are the best elements for connecting pipes and actuators. Quick and Easy to use, our Push-In Fittings can be re-used thousands of times without affecting the pneumatic and mechanical seal in any way.
It comes in various configurations and guarantees a virtually unlimited, highly flexible use. All of these fittings have cylindrical threading and incorporate a O-ring. The use of an O-ring considerably improves the seal of angled, rough and slightly convex surfaces. Sealing tape or thread dope is no longer used. Thread sizes available: M3, M5, M7, M12x1. Mounting fittings with an Allen wrench or pneumatic tool.
All elbows and TEEs are rotary. Drastic reduction in assembly times. The pipe is easy to assemble by pressing lightly on the pusher ring. To remove the fitting, merely push radially on the key.
