When dealing with pipe connections, selecting the right type of thread is crucial for ensuring secure, leak-free seals. Whether you’re a contractor, a wholesaler, or simply need fittings for personal projects, understanding the key differences between BSPP, BSPT, and NPT threads can make all the difference. We offer pipe nipples and galvanized pipe fittings tailored to your specific requirements, complete with OEM and ODM services.
BSPP, BSPT, and NPT Threads: What Are They?
BSPP (British Standard Pipe Parallel), BSPT (British Standard Pipe Taper), and NPT (National Pipe Thread) are commonly used thread standards for pipes and fittings. They play a significant role in many industries, especially for transporting liquids, gases, and steam in both high and low-pressure environments. But, these thread types are not interchangeable, which is why knowing the details is important.
- BSPP (Parallel Thread):
BSPP is a straight thread, where the male and female parts screw together without tapering. A key characteristic of BSPP is that it requires a sealing ring (O-ring or crush washer) to create a tight seal between the male and female parts. These threads are commonly used in Europe, Asia, Australia, and South Africa. - BSPT (Taper Thread):
BSPT threads, on the other hand, have a tapered profile, where the male and female threads gradually get tighter as you screw them together. This tapering creates a mechanical seal, but a thread sealant is often required for additional security. BSPT threads are popular in many plumbing systems and are especially common in British and Commonwealth countries. - NPT (Taper Thread):
Similar to BSPT, NPT threads are tapered, meaning that the thread diameter decreases or increases as you screw the connection. One of the major differences between NPT and BSPT is the thread angle; NPT threads have a 60° angle with flat peaks and valleys, while BSPT has a 55° angle with rounded peaks and valleys. NPT is widely used in North America and is the standard for many industrial applications.
While BSP and NPT threads may appear similar, their differences mean they cannot be used together without risking leaks. This is especially true for high-pressure applications, where mismatched threads can lead to failure.
Application of BSPP, BSPT, and NPT Threads
BSPP, BSPT, and NPT threads each have their own specific applications:
- BSPP threads are ideal for low-pressure applications or when precise flow control is needed. Since they do not self-seal, they are commonly used in hydraulic and pneumatic systems where a leak-free connection is essential.
- BSPT threads are used when self-sealing connections are crucial, such as in plumbing, gas systems, and high-pressure applications. BSPT threads can connect with both parallel and tapered female threads, offering a versatile solution.
- NPT threads, standard in the United States, are commonly used in piping systems for gas and liquids. Their self-sealing nature makes them a frequent choice in industries like oil and gas, chemical, and other heavy-duty sectors.

Ensuring a Leak-Free Connection
It’s important to choose the right fittings for the job to prevent leaks and failures. For example, while BSPT male threads can be connected to both BSPP (parallel) and BSPT (tapered) female threads, NPT and BSP threads are not compatible. This difference stems from their distinct angles and thread designs. If you attempt to use mismatched threads, it can lead to cross-threading, leakage, or even damage to your system.
Our fittings are designed to make installation as easy and secure as possible. We also offer expert advice on selecting the right product for your specific project needs. Whether you need GI fittings or pipe nipples, we ensure that each fitting meets international quality standards.
We Also Offer Pipe Nipples
Overview: A pipe nipple connects two fittings or pipes with female threads and is a short piece of pipe. Typically featuring male threads at both ends, pipe nipples play a crucial role in various plumbing and industrial applications. They come in different lengths and types, including “close nipples,” which have no unthreaded area and are nearly concealed when connected.
Manufacturers often use galvanized carbon steel to make pipe nipples, enhancing durability and corrosion resistance. These components serve both residential and industrial settings, connecting pipelines and fittings when a short length of pipe is needed.
Galvanized Carbon Steel Nipple Pipe Fittings
Galvanized carbon steel nipple pipe fittings are a short section of pipe with male pipe threads on both ends, designed to connect two female threaded galvanized steel pipes. These pipe nipples are essential in various industrial applications, offering durability and resistance to corrosion.
A “close nipple” has no unthreaded areas, making it virtually unexposed when connected between two female fittings. The length of the nipple includes the threads, making it suitable for outdoor environments and heavy-duty applications.
These fittings, made from zinc-coated steel, provide superior protection against rust, making them ideal for water, air, and steam applications. With compliance to industry standards such as ASTM A197, ASME B16.3, and B1.20.1, these fittings guarantee high performance and reliability.
Key Features:
- Male NPT threaded ends
- Hot-dip galvanized finish for corrosion resistance
- Suitable for outdoor and industrial applications
- Manufactured to ASTM and ASME standards
