KHSST Taper Pipe • Chamfer 2 1/2 to 3 1/2 Pitches

Features and benefits

• Manufactured from select high-speed steel.
• Ground thread pipe taps are standard in American Standard Pipe Form (NPT) and American Standard Dryseal Pipe Thread 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 sealer.
• The nominal size of a pipe tap is that of the pipe fitting to be tapped, not the actual size of the tap; thread taper is 3/4" per foot.
• Alternate tap coatings are available as stock modifications.
