Quad-Rings™, or lobed rings, as designed to take the place of a traditional O-ring. These products fit in the same grooves as O-rings, and function much the same.  Mold parting lines are located between the lobes, as opposed to one the actual sealing surface with O-rings.  This eliminates a leak path compared to an O-ring.
