The fluid filter includes a body. A plate is coupled to one end of the body, the plate having a first surface and a threaded portion having a thread pitch. A seal is disposed adjacent the plate, the plate having a second surface opposite the plate. A stop member is disposed adjacent the plate, the stop member having a third surface offset from the second surface. ## Claims ### Claim 1 A fluid filter comprising: a body; a plate coupled to one end of the body, the plate having a first surface and a threaded portion having a thread pitch; a seal disposed adjacent the plate, the seal having a second surface opposite the plate; a stop member disposed adjacent the plate, the stop member having a third surface offset from the second surface; wherein the third surface is offset from the second surface by amount between about three-quarters and about one thread pitch. ### Claim 2 (depends on 1) The fluid filter of claim 1 wherein the third surface is offset from the second surface by about an amount equal to three-quarters of the thread pitch. ### Claim 3 (depends on 2) The fluid filter of claim 2 wherein the threaded portion has 16 threads per inch. ### Claim 4 (depends on 1) The fluid filter of claim 1 wherein the offset is about 0.045 inches. ### Claim 5 (depends on 1) The fluid filter of claim 1 wherein the third surface is disposed between the first surface and the second surface. ### Claim 6 (depends on 5) The fluid filter of claim 5 wherein the stop member is made from a plastic material. ### Claim 7 A fluid filter comprising: a body having first and second ends; a plate coupled to the first or the second end of the body, the plate having a first surface and a threaded portion having a thread pitch; a channel member disposed adjacent the plate, the channel member defining an area with an open side opposite the first end and the channel member further including first and second peripheral edges; a sealing member disposed within the area, the sealing member having a second surface spaced a first distance from the open side; and, a stop member having a slot within a radial outer periphery of the stop member, wherein the first peripheral edge of the channel member extends into the slot to retain the stop member such that the stop member extends radially inwardly from the first peripheral edge of the channel member, the stop member having a third surface disposed between the first surface and the second surface. ### Claim 8 (depends on 7) The fluid filter of claim 7 wherein the third surface is offset from the second surface by a second distance, the second distance being between about three-quarters and about one thread pitch. ### Claim 9 (depends on 8) The fluid filter of claim 8 wherein said first distance is larger than said second distance. ### Claim 10 (depends on 9) The fluid filter of claim 9 wherein the second distance is about 0.045 inches. ### Claim 11 (depends on 7) The fluid filter of claim 7 wherein the channel member includes a lip disposed on an inner diameter. ### Claim 12 (depends on 11) The fluid filter of claim 11 wherein the slot of the stop member is coupled to the lip. ### Claim 13 (depends on 12) The fluid filter of claim 12 wherein the stop member is made from a plastic material. ### Claim 14 A fluid filter comprising: a body having first and second ends; a channel member having an outer diameter coupled to the second end of the body, the channel member including first and second opposing side walls and a bottom wall connecting the first and second opposing side walls, wherein the first and second opposing side walls and the bottom wall define an annular slot having an open side; a seal member disposed within the annular slot, the seal member having a first surface spaced from the open side; and, a stop member attached to the second side wall of the channel member such that the stop member extends radially outwardly from the second side wall, the stop member having a second surface disposed between the open side and the first surface. ### Claim 15 (depends on 14) The fluid filter of claim 14 wherein the second surface is offset from the first surface by about 0.045 inches. ### Claim 16 (depends on 14) The fluid filter of claim 14 wherein the channel member includes a lip portion along the inner diameter. ### Claim 17 (depends on 16) The fluid filter of claim 16 wherein the stop member includes a slot disposed along an outer diameter. ### Claim 18 (depends on 17) The fluid filter of claim 17 wherein the lip portion is disposed within the stop member slot. ### Claim 19 (depends on 14) The fluid filter of claim 14 further comprising a tapping plate coupled to the body on the second end, the tapping plate including a threaded portion having a thread pitch. ### Claim 20 (depends on 19) The fluid filter of claim 19 wherein the second surface is offset from the first surface by between about three-quarters and about one thread pitch. ### Claim 21 (depends on 7) The fluid filter of claim 7, wherein the stop member includes a vertical segment disposed adjacent an inner radial periphery of the second peripheral wall, a horizontal segment perpendicular to the vertical segment and extending radially outwardly from the vertical segment, wherein the slot is formed between the vertical and horizontal segments.
