VG-P816F-NS-20 Combination Group B (Cover): 1"W X 0.25"H X 240"L Grey Nolu-S (20ft Per Pack) Core Bits The top of breather isFeatures Ram extruded Ultra low friction dry lubricated UHMW PE (NS). Nolu S extrusions are a proprietary blend of UHMW PE and solid lubricants. Maintains good wear characteristics while significantly reducing coefficients of friction compared to standard UHMW. Unique self lubricating properties make it ideal for applications requiring reduced friction, noise reduction, and higher dry running speeds. Extends life of mating surfaces Reduces energy and
