Abstract
An inline filter having a swivel right-angle fitting for coupling an inlet or outlet tube. The fitting includes a stem having a pair of O-rings and a distal ridge and notch. The cap of the filter includes a port having a plurality of annular, resilient tabs that engage the notch and ridge to retain the fitting to the cap.
Claims11
An inline water filter, comprising:
- a generally cylindrical filter body having a first end and a second end and a longitudinal axis, said filter body defining a hollow interior and defining openings at each of said ends, said openings being in communication with said interior;
- a first cap attached to said filter body at said first end and sealing said opening at said first end, said first cap defining a circular port having annular resilient tabs;
- a second cap integral with said filter body at said second end, said second cap sealing said opening at said second end;
- a first substantially right-angle fitting having a cylindrical stem portion with an annular ridge engaging said annular resilient tabs of said first cap, said first fitting configured to connect a first tube to said filter, said first fitting being rotatable about the longitudinal axis;
- a second substantially right-angle fitting attached to said second cap, said second fitting configured to connect a second tube to said filter;
- and
- a quantity of a granulated activated carbon filtration media inside said filter body.

An inline water filter, comprising:
- an elongated generally tubular filter body defining a hollow interior;
- a first end cap attached to a first end of said filter body, the first end cap defining a port;
- a second end cap integrally formed with a second end of said filter body;
- a first substantially right-angle fitting attached to said first end cap, said first fitting communicating with the hollow interior of the filter body and having a first hollow stem portion that extends into said port and a second hollow head portion configured to connect to a first tube, the stem portion being rotatable about a longitudinal axis, and the first end cap having a plurality of resilient tabs surrounding the port that engage a ridge on the stem portion of the first fitting;
- at least one O-ring surrounding the stem portion of the first fitting and providing a water tight seal between the stem portion and the portion of the first cap defining the port;
- a second fitting integrally formed with said second cap, said second fitting communicating with the hollow interior of the filter body and being configured to connect to a second tube;
- a filtration medium inside said filter body;
- porous means for separating the filtration medium and the port of the first end cap;
- wherein unfiltered liquid enters said filter body through one of said first and second fittings and filtered liquid exits said filter body through another of said first and second fittings after passing through both the filtration medium and the porous means;
- and
- whereby relative rotation of said first substantially right angle fitting and said filter body allows for adjustment of a radial angle between said first and second fittings to permit flexibility of routing said first tube and said second tube.
