1. A method of sealingly coupling a hollow fiber bundle to a casing for encasing a bundle of hollow fibers comprising:

  • (a) providing an annular porous collar having first and second outer peripheral edges, said collar including pores having a pore size distribution of from about 5 μ

    m to about 500 μ

    m;

    (b) providing a casing having first and second longitudinal ends, said casing defining a central chamber, said chamber having a first and second open ends wherein said longitudinal ends of said casing each include an inner, lateral, annular lip proximal to each of said open ends;

    (c) coupling said first outer peripheral edge of said annular porous collar to at least one of said inner, lateral, annular lips of said casing;

    (d) retaining a bundle of hollow fibers having first and second longitudinal ends within said chamber;

    (e) permeating said longitudinal ends of said hollow fiber bundle with a fluid impermeable material;

    (f) joining said porous collar coupled to said casing to said hollow fiber bundle by penetration of said fluid impermeable material through said pores of said porous collar; and

    (g) curing said fluid impermeable material, wherein a fluid impermeable seal is formed between said bundle of hollow fibers, said casing and said annular porous collar.
