An end cap for sealing an end of a tubular wall is provided. The end cap includes a circular-shaped body having an inner surface defining an aperture that extends into the circular-shaped body but not completely through the circular-shaped body. The end cap further includes a sealing member disposed on at least a portion of the inner surface of the circular-shaped body. The end cap further includes first and second finger portions extending in a first direction from the circular-shaped body that are configured to removably engage first and second notches in the tubular wall such that the inner surface contacts an outer surface of the tubular wall and the end cap is removably attached to the tubular wall.
1. An end cap for sealing an end of a tubular wall, comprising:
a circular-shaped body having an inner surface and an outer surface, the inner surface defining a cylindrical-shaped aperture that extends into the circular-shaped body but not completely through the circular-shaped body, the inner surface having a first inner surface portion and a second inner surface portion, the first inner surface portion being substantially parallel to an outer end of the circular-shaped body, the second inner surface portion extending from an outer periphery of the first inner surface portion in a first direction and being substantially perpendicular to the first inner surface portion;
a sealing member disposed on the second inner surface portion of the circular-shaped body; and
first and second finger portions extending in the first direction from the circular-shaped body, the first finger portion having a first extension portion and a first tab portion, the first extension portion extending away from the circular-shaped body in the first direction, the first tab portion extending away from the first extension portion perpendicular to the first extension portion and toward the tubular wall, the second finger portion having a second extension portion and a second tab portion, the second extension portion extending away from the circular-shaped body in the first direction, the second tab portion extending away from the second extension portion perpendicular to the second extension portion and toward the tubular wall, the first and second tab portions being configured to removably engage first and second notches, respectively, that extend into the tubular wall such that the sealing member contacts an outer surface of the tubular wall and the end cap is removably attached to the tubular wall.
2. The end cap of claim 1 , wherein the first and second finger portions are centered on a plane that bisects the circular-shaped body into two-equal sized regions.
3. The end cap of claim 1 , wherein the sealing member is constructed of an elastomer.
4. The end cap of claim 3 , wherein the elastomer is at least one of styrene, ethylene, butylene, propylene, and diene.
5. The end cap of claim 1 , wherein the sealing member has a first surface that is disposed on the second inner surface portion, and an arcuate shaped surface that is configured to contact the outer surface of the tubular wall.
6. The endcap of claim 1 , wherein the first tab portion has a chamfered portion that is received within the first notch in the tubular wall.
7. An end cap for sealing an end of a tubular wall, comprising:
a circular-shaped body having an inner surface and an outer surface, the inner surface defining an aperture that extends into the circular-shaped body but not completely through the circular-shaped body, the inner surface having a first inner surface portion and a second inner surface portion, the first inner surface portion being parallel to an outer end of the circular-shaped body, the second inner surface portion extending from an outer periphery of the first inner surface portion in a first direction and being perpendicular to the first inner surface portion;
a sealing member having a first surface that is disposed on the second inner surface portion of the circular-shaped body, and an arcuate shaped surface that is configured to seal against an outer surface of the tubular wall; and
first and second finger portions extending in the first direction from the circular-shaped body, the first finger portion having a first extension portion and a first tab portion, the first extension portion extending away from the circular-shaped body in the first direction, the first tab portion extending away from the first extension portion perpendicular to the first extension portion and toward the tubular wall, the second finger portion having a second extension portion and a second tab portion, the second extension portion extending away from the circular-shaped body in the first direction, the second tab portion extending away from the second extension portion perpendicular to the second extension portion and toward the tubular wall, the first and second tab portions being configured to removably engage first and second notches, respectively, that extend into the tubular wall such that the arcuate shaped surface of the sealing member contacts the outer surface of the tubular wall and the end cap is removably attached to the tubular wall.
8. The end cap of claim 7 , wherein the sealing member is constructed of an elastomer.
9. The endcap of claim 8 , wherein the first tab portion has a chamfered portion that is received within the first notch in the tubular wall.
