Electronics module enclosure

An electronics housing comprising:

• a first enclosure portion defining an internal cavity;
• a second enclosure portion at least partially covering said internal cavity;
• at least one vent positioned in one of said first enclosure portion and said second enclosure portion;
• said vent comprising a through hole protruding from an exterior edge of the vent to an interior edge of the vent, through hole including a radially interior tapered surface, wherein the radially interior tapered surface extends an entire length of the through hole;
• a malleable sealing member disposed in said vent, wherein the malleable sealing member is a malleable spheroid and wherein the malleable sealing member contacts a full circumference of the tapered surface while the vent is closed;
• a rigid retaining member disposed in said vent and directly contacting said malleable sealing member, wherein the rigid retaining member is a rigid spheroid and is maintained in position within said vent via an interference fit with the radially interior tapered surface of said vent;
• and
• wherein the internal cavity is sealed by a combination of the second enclosure portion, the at least one vent, and the malleable sealing member.
