A new design for an old item. This oil filler has a nice smooth look along with a low profile smooth cap design. Knurled cross-groove design on cap allows for good grip even when it's wet or oily. The filler body and cap are made from 6061 T-6 and fully polished to a show car shine! Supplied with gasket, o-ring, and 1/4" NPT - 1/2" barbed hose fitting so breather line hookup is easy.
