NPT (National Pipe Tapered Thread)

NPT threads are the most commonly used tapered threads in North America, designed to create a secure, leak-tight seal through the wedging action of the thread surfaces. With a thread angle of 60° and a taper of 1/16 inch per foot, NPT is suitable for various applications, including plumbing, gas transport, and industrial processing. B2B buyers should consider the importance of precise installation, as misalignment can lead to leaks, thus affecting operational efficiency.

NPTF (National Pipe Tapered Fuel Thread)

NPTF threads are tailored for fuel applications, offering tighter tolerances compared to standard NPT. These threads are essential for ensuring a leak-free connection in fuel systems and hydraulic applications. The enhanced sealing capability makes NPTF a preferred choice for sensitive applications where fluid loss can lead to significant safety and financial risks. Buyers should weigh the benefits of improved sealing against the potentially higher costs associated with tighter manufacturing specifications.

NPS (National Pipe Straight Thread)

NPS threads feature a straight design, making them easier to align than tapered threads. They are often used in conjunction with sealing compounds to ensure a leak-tight connection. Common applications include water supply systems and HVAC installations. B2B buyers should consider that while NPS threads simplify installation, they may require additional sealing measures, which can increase overall costs and complexity.

NPTF-L (National Pipe Tapered Fuel Thread with Locking Feature)

The NPTF-L design incorporates a locking feature to prevent loosening under vibration, making it ideal for high-pressure gas and hydraulic systems. This variation enhances safety and reliability in demanding environments. Buyers should evaluate the installation complexity against the benefits of increased security and reduced risk of connection failure, especially in critical applications.

BSPT (British Standard Pipe Tapered)

BSPT threads are widely used outside of North America, particularly in Europe. They are similar to NPT threads but differ in dimensions, which can lead to compatibility issues without the proper adapters. This makes BSPT a common choice for international plumbing and fitting applications. B2B buyers should be mindful of the regional standards and ensure compatibility with existing systems to avoid costly modifications.
