Custom Builder Eric Drouillard introduces his new FINNED OIL CAP. Reminiscent of finned styling in retro automotive designs; this cap will add the finishing touch to your sweet custom. Sand cast from 6061 aircraft grade aluminum, it features a double Buna N o-ring seal for a no leak fit. The FINNED OIL CAP will fit on any Harley or custom with a 1.25” ID push-in filler neck. Creating a custom oil tank? Just use 1.5" X .120" tubing for the filler neck (also available through Toxic Choppers) and the FINNED OIL CAP is ready to go! Made in the USA.
