Claims
- 1. A monolithic molded plastic component adapted for receiving an O-ring comprising:
- a plastic member having a bore therethrough, the member having a first and second set of monolithic castellations projecting inwardly into the bore and encircling the bore, and having an annular wall between the first and second castellations thereby defining a gap therebetween into which an O-ring may be received.
- 2. The plastic component of claim 1 wherein the member includes one or more apertures each having a periphery and further comprising filtration material extending across each of the apertures and molded into the component about the periphery of each of the apertures.
- 3. A monolithic molded plastic component adapted for receiving an O-ring of generally circular cross-section comprising:
- a plastic member having a bore therethrough thereby defining an axis, and having a first and second set of monolithic castellations projecting inwardly toward the axis and encircling the bore, and an annular wall therebetween, the first and second set of castellations generally defining respective first and second quarter-toroidal surfaces, the first quarter-torroidal surface separated from the second quarter-torroidal surface along the axis, whereby the first set of castellations and second set of castellations provide a semi-toroidal gap into which the O-ring may be received.
- 4. The plastic component of claim 3 wherein the member includes one or more apertures each having a periphery and further comprising filtration material extending across each of the apertures and molded into the component about the periphery of each of the apertures.
- 5. A monolithic molded plastic component adapted for receiving an O-ring of generally rectangular cross-section comprising:
- a plastic member having a bore therethrough thereby defining an axis, the member having a first and second set of monolithic castellations projecting inwardly toward the axis and encircling the bore, and an annular wall therebetween, the first and second set of castellations generally defining respective first and second planar surfaces generally orthogonal to the axis, the first planar surface separated from the second planar surface along the axis, whereby the first set of castellations and second set of castellations provide a rectangular gap into which the O-ring may be received.
- 6. The plastic component of claim 5 wherein the member includes one or more apertures each having a periphery and further comprising filtration material extending across each of the apertures and molded into the component about the periphery of each of the apertures.
