## Abstract

A fluid filter such as an oil filter for a vehicle is provided. The fluid filter includes a body having a first, closed end and a second, open end. A plate is coupled to the second end, the plate having a first surface and a threaded portion having a thread pitch. A channel member has an outer edge coupled to the second end of the body, wherein the channel member defines a recess with an open side opposite the first surface of the plate. A stop member is disposed within the recess of the channel member, the stop member having a first height. A sealing member is coupled to the stop member, and the sealing member has a second height greater than the first height of the stop member.

## Claims

### Claim 1

A fluid filter comprising:
a body having a first, closed end and a second, open end;
a plate coupled to the second end of the body, the plate having a threaded portion;
a channel member having an outer edge coupled to the second end of the body, the channel member defining a recess;
a stop member disposed within the recess of the channel member, wherein the stop member includes a first surface with a first groove and a second, opposite surface with a second groove;
a first sealing member coupled to the first groove of the stop member and a second sealing member coupled to the second groove of the stop member, the first sealing member having a first height extending beyond the first surface of the stop member and the second sealing member having a second height extending beyond the second surface of the stop member;
wherein the first height of the first sealing member is offset from a height of the first surface of the stop member by a first distance, and the second height of the second sealing member is offset form a height of the second surface of the stop member by a second distance; and
wherein a combination of the first distance and the second distance is about an amount that equates to three-quarters of the thread pitch of the threaded portion.

### Claim 2

A fluid filter comprising:
a body having a first, closed end and a second, open end;
a plate coupled to the second end of the body, the plate having a threaded portion;
a channel member having an outer edge coupled to the second end of the body, the channel member defining a recess;
a stop member disposed within the recess of the channel member, wherein the stop member includes a first surface with a first groove and a second, opposite surface with a second groove;
a first sealing member coupled to the first groove of the stop member and a second sealing member coupled to the second groove of the stop member, the first sealing member having a first height extending beyond the first surface of the stop member and the second sealing member having a second height extending beyond the second surface of the stop member;
wherein the first height of the first sealing member is offset from a height of the first surface of the stop member by a first distance, and the second height of the second sealing member is offset form a height of the second surface of the stop member by a second distance; and
wherein a combination of the first distance and the second distance is about an amount between three-quarters and one of a thread pitch of the threaded portion.

### Claim 3 (depends on 2)

The fluid filter of claim 2, wherein the channel member includes a projection extending outwardly from an inner surface of a side wall, and the stop member includes a groove on an outer surface thereof that couples with the projection of the channel member.

### Claim 4 (depends on 2)

The fluid filter of claim 2, wherein the channel member includes a groove in an inner surface of a side wall, and the stop member includes a projection extending outward from an outer surface thereof which couples with the groove of the channel member.

### Claim 5 (depends on 2)

The fluid filter of claim 2, wherein the stop member is plastic.

### Claim 6 (depends on 2)

The fluid filter of claim 2, wherein a combination of the first distance and the second distance is about 0.045 inches.

### Claim 7 (depends on 2)

The fluid filter of claim 2, wherein the first distance is approximately the same as the second distance.
