The SFSK oil analysis kits contain the equipment for sample extraction from the STAUFF test coupling or directly from a container or oil tank. To do this, the supplied hose is connected directly to the test coupling using an adaptor and the fluid is filled into the supplied sample bottle. But the sample can also be extracted directly from a container using the hand pump and filled into the sample bottle. The sample extraction kit is available in two versions with BSP and with NPT test couplings.
