Tubular, continuous, seamless, compressible, resilient mounting article comprising inorganic fibers, and having an inner curved surface, a central longitudinal axis, and a uniform internal cross-sectional area along the central longitudinal axis. The mounting articles are useful, for example, in mounting pollution control elements in pollution control devices.

1. A mounting article having a continuous and seamless tubular shape independent of a pollution control element, with first and second opposed open ends, a cross section deformable in any direction by at least 2% without breaking, a wall thickness compressible up to and including 60% without applying a compressive force exceeding 1000 kPa, an outer surface, an inner surface, at least a portion of which is curved, a central longitudinal axis, and a uniform internal cross-sectional area along the central longitudinal axis, wherein the mounting article comprises inorganic fibers. 2. The mounting article of claim 1 having a Resiliency Value after three thermal cycles from 25° C. to 900° C./530° C. of the Real Condition Fixture Test of at least 20 kPa. 3. The mounting article of claim 1 having a Resiliency Value after three thermal cycles from 25° C. to 900° C./530° C. of the Real Condition Fixture Test in a range from 20 kPa to 1400 kPa. 4. The mounting article of claim 1, wherein the mounting article as-made prior to heating above 500° C. contains not greater than 1 percent by weight organic material, based on the total weight of the mounting article. 5. The mounting article of claim 1, wherein the mounting article as-made prior to heating above 500° C. contains zero percent by weight organic material, based on the total weight of the mounting article. 6. The mounting article of claim 1, has one layer forming its outer surface and another layer forming its inner surface. 7. The mounting article of claim 6, wherein each layer is different. 8. The mounting article of claim 6, wherein each layer is either an intumescent layer or a non-intumescent layer, but they are not both intumescent or non-intumescent layers. 9. An article comprising the mounting article of claim 1 and a pollution control element having an outer surface frictionally contacting the inner surface of the mounting article, wherein the mounting article is in a stretched state with the inner surface of the mounting article being under tension. 10. A pollution control device comprising the article of claim 9 disposed in a casing. 11. The article of claim 9, wherein the pollution control element has an outside diameter, and when the mounting article is separate from the pollution control element, the mounting article has an inside diameter that is smaller than the outside diameter of the pollution control element. 12. An article comprising a pollution control element having an outer surface, the mounting article of claim 1, and a polymeric material covering disposed so as to provide a compressive force onto the outer surface of the mounting article that causes the inner surface of the mounting article to frictionally contact the outer surface of the pollution control element. 13. The article of claim 12, wherein the polymeric material cover is a polymeric shrinkable film covering the outer major surface of the mounting article, with the polymeric shrinkable film being shrunk so as to put the outer surface of the mounting article under compression. 14. The article of claim 13, wherein each of the opposing open ends of the mounting article has a seamless annular edge covered by the polymeric covering. 15. The article of claim 14, wherein the film is in the form of a tube. 16. The article of claim 13, wherein the film is in the form of a tube. 17. A pollution control device comprising a pollution control element mounted in a casing with the mounting article of claim 1. 18. A method comprising: providing a mounting article of claim 1; andapplying a shrinkable polymeric film over the outer surface of the mounting article. 19. The method of claim 18, wherein the polymeric film is a heat shrinkable polymeric film, and the method further comprises: heating the heat shrinkable polymeric film such that the film shrinks around the outer surface of the mounting article. 20. A method comprising: providing a mounting article of claim 1 having an inner surface, an inner circumference and inner geometric shape;a pollution control element having an outer surface, an outer circumference and an outer geometric shape, wherein the inner circumference of the mounting article is smaller than the outer circumference of the pollution control element, and the first and second geometric shapes are generally the same; anddisposing the mounting article around the pollution control element, at least in part, using a cone-shaped expanding wedge such that the inner surface of the mounting article is under tension and the outer surface of the pollution control element is frictionally contacting the inner surface of the mounting article.
