Features and Benefits
NPTF (National Pipe Taper Fuel) refers to Dryseal American National Standard Tapered Pipe Threads. They do not require a sealant due to being formed by metal to metal contact.
High Speed Steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and non-ferrous materials.
Blue Diamond is a specially treated electrochemical coating designed to prevent surface welding when tapping soft, stringy materials. Blue Diamond is a proprietary coating exclusive to Reiff & Nestor Company.
