1. An assembly for providing a radial seal between two air conduit members;
- said assembly comprising;
(a) a first conduit member having an open end including a seal retainer thereon;
said seal retainer including a retainer trough;
(i) said retainer trough having at least three sidewalls;
said three sidewalls comprising a front wall adjacent said open end, a rear wall and a frusto-conical sidewall extending therebetween;
said frusto-conical sidewall increasing in diameter from said front wall to said rear wall(b) a compressible seal ring operably positioned within said retainer trough;
said seal ring, when in an uncompressed state, comprising elastomeric material and having;
(i) first, second and third outside walls including first and second opposite end walls;
said first wall engaging said front wall, said second wall engaging said rear wall and said third wall engaging said frusto-conical sidewall;
(ii) an inner surface defining a central aperture therethrough;
said seal ring inner surface being stepped, in decreasing diameter, in a direction of extension from said first end wall to said second end wall;
(iii) said seal ring third outside wall being opposite said seal ring inner surface and having a frusto-conical configuration of increasing outside diameter in a direction of extension from said first end wall to said second end wall;
(iv) said seal ring being sized to fit between said trough front and rear walls, in use.(c) a second conduit member having a tubular section constructed and arranged for insertion through said open end and through said seal ring central aperture when said seal ring is nested within said retainer trough;
said tubular section being sized to cause compression of said seal ring sufficiently for formation of a radial seal with said seal ring inner surface, when said second conduit tubular section is inserted through said seal ring central aperture;
(i) said retainer trough being sized to receive said compressible seal ring without compression of said seal ring in a direction between said seal ring inner surface and said seal ring outside wall, before said second conduit member is operably inserted into said seal ring central aperture.
