Features and benefits

• Manufactured from select tap high-speed steel.
• Ground thread pipe taps are standard in American National Standard Straight Pipe (NPS) thread form and American National Standard Dryseal Straight Pipe (NPSF) thread form.
• NPS threads are suitable for tapping holes or couplings for low pressure work when used with a sealer; also suitable for NPSC and NPSM work.
• NPSF dryseal taps are intended for low pressure work, such as fuel and oil lines where a sealer is not used.
• Dryseal threads give a low-pressure, pressure-tight joint without the use of a sealer.
