PRP Stealth Filler Caps


PRP Stealth Filler Caps

PRP’s Stealth Filler Caps are great addition where a filler cap is needed. These universal caps will fit applications including: Valve covers, rear ends, inspection covers and overflow tanks. Each cap kit features a screw in cap with an O-ring for positive sealing.

PRP’s Stealth line is comprised of existing products that are anodized in a Gun Metal finish with a special PRP Stealth logo. The line only includes top selling products which we have taken to the next level with this tricked out finish. The logo change was also an added feature to distinguish between our standard line and our new Stealth line.
