DMS 12an ORB Oil Filler Cap Adapter LS and LT 6an, 8an, 10an, 12an, 16an
We've been making these oil filler cap adapters for the better part of 10 years for use with our turbo kits. They've always been a -8an for our scavenge pump return. We're now offering these with a female -12an ORB thread giving you the option to select a 6an, 8an, 10an, 12an or 16an male fitting. These work on all known OEM GM valve covers found on LS and LT engines, with or without the plastic filler adapter. These will even fit on the GM dry sump tanks. These are great for making custom catch can kits, scavenge oil tank returns or any other project where you require a AN fitting in the valve cover.
- Adapter thread size is 12an ORB: Pitch 1 -1/16 12 UNF
- Billet Aluminum
- Anodized Black
- High Temp Silicone O-ring included
