How to ensure optimum sealing of the oil filter element

Installation of certain oil filter elements can feel tight in comparison to alternative filter element designs. Rest assured, any tightness is normal and ensures optimum sealing of the element.

Tight is right!
Many original equipment MANN-FILTER oil filter elements have end caps which seal radially to the relevant matching part in the oil filter housing (usually a plastic centre tube). This is achieved through the precise fit of the inside diameter bead of the filter end caps.
