This tee fitting is ideal for adding a Fuel Sampling Port (Part No. 2542) to rubber fuel line using a pair of barbed hose adapters. It is also perfect for adding an aftermarket oil pressure gauge to a factory warning light switch port without losing the warning light switch.
Brass is acceptable for pressure gauges and fuel systems, but if you need a similar fitting for higher pressure applications, we also offer a Steel 1/8 NPT Female Tee, Part No. 3223.
Note: NPT nomenclature can be confusing because the nominal size refers to the inside diameter of the pipe, not the outside diameter of the threads. Male 1/8 NPT threads measure approximately 3/8" OD. For more information, check in our Guide to Using NPT Fittings.
