Series 5321 • Standard Pipe Chamfer • Standard Projection

Features and benefits

• Manufactured from select tap high-speed steel.
• Ground threads standard in American Standard Pipe Form (NPT) and American Standard Dryseal Pipe Form (NPTF).
• NPT threads require the use of a sealer, such as Teflon® tape or pipe compound.
• NPTF dryseal threads give a pressure-tight joint without the use of a sealer.
• Uncoated taps standard; coatings available as a stock modification.
• Spiral flutes lift chips out of the tapped hole reducing stop lines.
• Most effective in materials that produce long, stringy chips.
