Bidirectional airflow attachment hose and methods of use

A bidirectional airflow connector assembly comprising

• an elastomeric connector having an opening therethrough comprising a body portion and a connector flange portion at a distal end thereof;
• wherein the connector flange portion is approximately perpendicular to the body portion;
• a rigid compression fitting having an opening aligned with the opening of the elastomeric connector;
• wherein the rigid compression fitting comprises a female cap, a double sided male component, and an insert having dimensions to fit therebetween;
• wherein the insert comprises a tube portion and an insert flange portion, wherein the insert flange portion is approximately perpendicular to the tube portion;
• wherein the insert flange portion is proximate a first end of the insert and is about the same circumference as the connector flange portion;
• wherein the tube portion is proximate a second end of the insert and has a length that is shorter than a length of the elastomeric connector and has an outer circumference that is about the same as the inner circumference of the elastomeric connector;
• wherein the double sided male component comprises a male hose end;
• and
• wherein a proportion of an inner diameter of the tube portion proximate the insert flange portion to a narrowest inner diameter of the male hose end, or a proportion of an inner circumference of the tube portion proximate the insert flange portion to the narrowest inner circumference of the male hose end, is 2:1 or less.
