Abstract
A multi-component end cap is provided. The multiple components combine to form one or more seal carriers where each seal carrier is formed in part by at least two different ones of the components. Methods of manufacturing an end cap having multiple components are also provided.
Claims23
An end cap for a filter element comprising:
- a first annular component;
- a second annular component secured to the first component, the first and second annular components defining a radially directed flow path therebetween;
- an outer seal defining a radially outward directed sealing surface and a secondary sealing surface;
- an outer seal carrier defined in part by the first annular component and in part by the second annular component, the outer seal carrier axially securing the outer seal therein and configured to expose the radially outward directed sealing surface of the outer seal, the outer seal carrier defining a first sealing surface, the secondary sealing surface of the outer seal sealingly contacting the first sealing surface of the outer seal carrier.

A filter arrangement comprising:
- an end cap comprising:
- a first annular component;
- a second annular component secured to the first component, the first and second annular components defining a radially directed flow path therebetween;
- an outer seal defining a radially outward directed sealing surface and a secondary sealing surface;
- an outer seal carrier defined in part by the first annular component and in part by the second annular component, the outer seal carrier axially securing the outer seal therein and configured to expose the radially outward directed sealing surface of the outer seal, the outer seal carrier defining a first sealing surface, the secondary sealing surface of the outer seal sealingly contacting the first sealing surface of the outer seal carrier;
- filter media secured to an inner side of the second annular component;
- a housing having an annular sidewall defining an open end and a central cavity, the sidewall defining a third sealing surface that is radially inwardly directed, the radially outward directed sealing surface sealingly contacting the third sealing surface, the filter media being positioned within the central cavity of the housing.

A method of forming an end cap for a filter element where the end cap provides a radially directed flow path through the end cap, the method comprising:
- forming a first annular component;
- forming a second annular component that is separate and independent of the first annular component;
- securing the second annular component to the first annular component such that the radially directed flow path is formed between the first and second annular components.
