From NPT to BSP, Jarvis manufactures application-specific cutting and roll-forming pipe taps using advanced materials, coatings, and processes to keep you ahead of industry demands.
INFORMATION
In 1949, Mueller Water Products patented the tamper-proof gas valve which included several tapered pipe threaded holes as part of the design. That same year, Jarvis Cutting Tools began producing Pipe Taps manufactured to the National Pipe Thread specifications developed by the American Standards Association thirty years earlier.
We continue to be the leader in the manufacturing application specific cutting and roll forming taps to meet all thread standards including National and British Whitworth . Our customer’s focus is quality and throughput. Jarvis supports this focus by providing application specific standards and made to order specials produced using innovating manufacturing process on modern equipment. Our customers also benefit from Jarvis’ close relationship with our suppliers. We are actively involved in testing new PM steels, coatings and machining processes. The innovations we bring to market enable our customers to stay on the cutting edge of technology. All of our work is focused on providing you with the optimal tool for your process and goals.

APPLICATIONS
INFORMATION
A plumber’s toolbox isn’t complete without a full set of pipe taps. Don’t get caught without the right tap for the job!
NPT pipe taps are used to create threads (or to rethread) metal piping and fittings.
Our taps provide superior thread ensuring a tight seal.
Typical plumbing application is the threading of piping used to transfer liquids & gases.
Our taps can be used with aluminum, brass, copper or steel.

BASICS
American National Standard Pipe Thread standards, often called national pipe thread (NPT) standards for short, are US national technical standards for screw threads used on threaded pipes and pipe fittings. They include both tapered and straight thread series for various purposes including rigidity, pressure-tight sealing, or both.[1] The various types are each named with a symbol and a full name; examples of the symbols include NPT, NPS, NPTF, NPSC, and others. [For full writeup + Charts: Go to NPT Wikipedia]
NPT (National Pipe Taper) high speed steel pipe taps
NPT joints generally require a sealant
NPTF (dryseal) is called for in high pressure situations
Interrupted Thread Facilitates chip removal. Recommended for use in soft, ductile materials such as aluminum. After the lead, every other thread in an interrupted thread pipe tap is removed to minimize the clogging of the threads.
NPS Straight Thread Straight Pipe Taps. For cutting NPS (straight) pipe threads. NPS threads are frequently found on pipes, lamps and lighting fixtures.
Long Taper Pipe Taps Extension Pipe Taps [ex: 6 OAL / Over All Length]
British Standard Pipe (BSP) BSP technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings by mating an external (male) thread with an internal (female) thread. It has been adopted as standard in plumbing and pipe fitting, except in North America.
Commonly used US sizes are 1⁄8, 1⁄4, 3⁄8, 1⁄2, 3⁄4, 1, 1 1⁄4, 1 1⁄2, 2, 2 1⁄2, 3, 4, 5, & 6 inch
