Vacuum conduit attachment tools

A method of assembling a vacuum attachment tool including a hollow body extending from a first end to a second end and including a vacuum conduit connector disposed at the second end, the method comprising:

• positioning an outer collar of the conduit connector relative to an inner collar of the conduit connector such that the inner and outer collars are co-axial, wherein the inner collar has an inner diameter sized to receive a first vacuum conduit having a first diameter, wherein the inner collar includes a deflectable tab including a plurality of teeth operable to engage a locking mechanism of the first vacuum conduit, and wherein the outer collar has an inner diameter sized to receive a second vacuum conduit having a second diameter greater than the first diameter;
• moving the outer collar relative to the inner collar such that the inner collar is received within the outer collar;
• and
• coupling the outer collar to the inner collar.

A vacuum attachment tool comprising:

• a hollow body formed circumferentially about a central axis, wherein the hollow body extends from a first end to a second end and defines a flow path;
• and
• a conduit connector disposed at the second end of the hollow body, wherein the conduit connector comprises:
• an inner collar formed about the central axis and including:
• a radial inner surface having an inner diameter sized to receive a first vacuum conduit having a first diameter;
• a radial outer surface;
• a deflectable tab including a first plurality of teeth operable to engage a locking mechanism of the first vacuum conduit, wherein at least one tooth of the first plurality of teeth includes a first portion and a second portion spaced circumferentially from the first portion by a recess;
• and
• a first plurality of ribs positioned on the radial outer surface of the inner collar, the first plurality of ribs including at least one alignment rib;
• and
• an outer collar formed separately from and coupled to the inner collar, the outer collar including:
• a radial inner surface having an inner diameter sized to receive a second vacuum conduit having a second diameter greater than the first diameter;
• a radial outer surface;
• a second plurality of teeth positioned on the radial outer surface of the outer collar and operable to engage a locking mechanism of the second vacuum conduit;
• a plurality of locking fingers operable to engage at least one rib of the first plurality of ribs of the inner collar to couple the outer collar to the inner collar;
• and
• a second plurality of ribs positioned on the radial inner surface of the outer collar, at least one rib of the second plurality of ribs including a crushing portion operable to engage the first plurality of ribs of the inner collar via the crushing portion when the outer collar is coupled to the inner collar, the second plurality of ribs further including at least one alignment rib, wherein the at least one alignment rib of the second plurality of ribs is operable to engage the at least one alignment rib of the first plurality of ribs when the outer collar is coupled to the inner collar, wherein engagement of the alignment ribs aligns the outer collar relative to the inner collar and restricts rotation of the outer collar relative to the inner collar.
