To eliminate non-filtered oil from circulating in an engine's oil system, JEGS O-Ring Non-Bypass Oil Filter Adapter changes the stock Chevy oil filter adapter with standard bypass valve (which is prone to break) to a heavy-duty non-bypass. No longer do you need to weaken the stock adapter with plugs, screws, or epoxy that could loosen and damage the oil system. Mounting hardware included.
Notes
Intended for performance engines only
Designed for 1968-Up Chevy blocks originally equipped with spin-on filter
