NPT stands for National Pipe Taper thread. It’s a tapered thread standard commonly used in North America for pipe and fitting connections in various applications, including: Key features of NPT threads: Tapered threads: The threads have a slight taper, meaning they gradually get narrower towards the end. This taper creates interference when the threads are tightened, […]

British Standard Pipe Tapered (BSPT) is a type of pipe thread used in the United Kingdom and other Commonwealth countries. It is a tapered thread, which means that the diameter of the thread gets larger or smaller as it goes along the length of the pipe. This taper helps to create a tight seal when […]
What is BSPP Threads The British Standard Pipe Parallel (BSPP) is a thread used to connect pipes and fittings. It’s a parallel thread, meaning that the sides of the thread are straight, as opposed to tapered like BSPT threads. This makes it easier to assemble and disassemble, but it also means that it’s not as […]
Here’s a breakdown of the thread specified in DIN 3852-2: Key Points: Thread Type: It primarily designates parallel threads, but also includes a tapered thread variant. Standard Scope: Covers dimensions, types, and designations for stud ends used in fittings, valves, and port plugs. Relationship to ISO Standards: Closely aligns with ISO 1179-1 for parallel threads, but offers additional […]
NPT and NPTF threads are both commonly used tapered pipe threads in plumbing and piping systems, but they have some key differences: Sealing: NPT (National Pipe Taper): Requires a sealant, like Teflon tape or pipe dope, to create a leakproof connection. The threads themselves don’t provide a perfect seal, so the sealant fills in any gaps and […]
