*** IN STOCK SHIPS TODAY *** 1/8" NPT steel pipe plug. RBS offers the racer this steel internal hex plug that comes with thread sealant already on it so all you need to do is send the plug into it's new home and within seconds you are done.
Plugs are handy to have if installing different injectors on a engine as most injectors have extra 1/8" NPT holes for the racer to run as many or as few of fuel lines as their record smashing tune-up calls for. Extra 1/8" NPT holes no issue, grab a plug, 3/16" Allen wrench and that fast problem solved.
Finish is black oxide steel and threads are coated in a dry Teflon sealant.
Plugs are sold each.
