AN to NPT Adapter Fittings & Connectors

An AN to NPT adapter connector(s), when combined with thread sealing tape or thread sealant, provides a leak-free connection for your fuel, transmission, oil, coolant, or other low-pressure systems on your car, truck, or race vehicle with a solid design.

Upgrading existing NPT In-line adapter fittings and other connectors provides another level of detail when raising the hood on your race or street vehicle. Available in steel, brass, aluminum, and stainless steel, NPT adapter fittings are manufactured in different finish options such as anodized, polished, or chrome. Once installed, these fittings will draw additional attention to your vehicle on the street or in the pit area at the track.

An NPT adapter is a fitting (usually made from aluminum, steel, brass, or stainless steel) that connects two different sizes or styles of fittings together. Examples include AN (aircraft), NPT, inverted flare, hose barb, as well as other types. Adapters are usually straight but are often available in different angles such as 45 or 90 degrees.

AN fittings are usually made from aluminum, stainless steel, or steel. Sizes will range from -2 through -32, typically in even steps with each step equal to 1/16" for the measurement of the outside diameter of the tubing. For example, a "-6" fitting size is equal to 6/16", or 3/8". The fitting is flared at a 37-degree angle, which provides excellent sealing and flow properties. An AN hose fitting involves 2 pieces, which includes a socket and a nipple. The socket fits onto the end of the hose and the nipple fitting pushes into the hose end, with the help of metal or nylon vise jaws, which hold the socket while the nipple fitting draws into it. The two pieces are joined together via threads and once tight, the connection is complete as the hose is squeezed between the two. AN fittings were created during World War II by the Army and Navy, and thus named "AN fitting". After WWII, the fittings were used throughout the aviation and automotive performance industry and continue to be used today. AN fittings can be used as water pump fittings, transmission fluid cooler fittings, fuel pump fittings, and more in automotive applications.

When you are plumbing your fuel, oil, coolant, vacuum, or other system for your car, truck, or race vehicle, fittings are needed, which can include AN to NPT adapters and connectors. These fittings are designed to provide leak and trouble-free connections that will last a long time. Make JEGS your #1 source for AN to NPT adapters, fittings, and connectors today!
