Krytox GPL407潤滑液脂在40°C時的柴油機油黏度為440 cSt，相信可溫度因素空間為-70–316°C。Chemours工司產出的Krytox GPL 407防銹液脂選用非熔融增稠劑，而都是普通級的Krytopx PTFE。類似這些從聚四氟氯氯乙烯到二陽極氧化硅的變化將防銹液脂的工作的溫濕度力量從約316°C（600°F）延長到由油的減壓蒸餾/分解掉工作的溫濕度知道的下限。Krytox GPL-407由Krytox-GPL-107發動機油做出，在適宜空氣流通的情況下下，該發動機油行瞬時接受399°C（750°F）和更大的工作的溫濕度。能夠補足/如何防銹液，它行連續性更長久間隔。盡管Krytox GPL-407并不開始打算在288–316°C（550–600°F）這的工作的溫濕度下成為Krytox GPL-200品類，但它仍然將氟化防銹液脂的選用范圍圖加大到PTFE和Teflon的316°C（600°F? 稠化防銹液脂。Krytox GPL 407比聚四氟氯氯乙烯增稠防銹液脂含有更大的油提取度，故此在同樣環境下幾率不會輕易連續性因此長久間隔。

Krytox GPL407 grease has an Oil Viscosity of 440 cSt at 40°C and the estimated useful temperature range is  –70–316 °C.Krytox GPL 407 grease from Chemours is made using a non-melting thickener, instead of the normal Krytox PTFE. This change from PTFE to silica boosts the temperature capability of the grease from approximately 316 °C (600 °F) to an upper limit determined by the evaporation/breakdown temperature of the oil. Krytox  GPL-407 is made from Krytox? GPL-107 oil, which, with proper ventilation, can withstand up to 399 °C (750 °F) and higher temperatures for brief periods. With replenishment/re-lubrication, it can last longer.While Krytox GPL-407 is not meant to replace the Krytox GPL-200 series at temperatures below 288–316 °C (550–600 °F), it does extend the range for using fluorinated greases to beyond the 316 °C (600 °F) limit of PTFE and Teflon? thickened greases. Krytox  GPL 407 has higher oil separation than PTFE thickened greases and, therefore, might not last as long under equivalent conditions.
