W. L. Gore & Associates’ Series: AVS 41 (P/N VE2048) venting solution is engineered specifically to protect transmissions, transfer cases, power transfer units, axles, and limited-slip couplings from extreme operating conditions. The continuous airflow of the automotive vents equalizes internal pressure, therefore improving reliability by reducing vacuum and premature failure of housing seals, according to the company. In addition to airflow, the vent’s membrane provides resistance to contamination from dust, dirt, water spray, flooding and freezing. The pre-filter protects the membrane from lubricant particles in the air stream, and the protective cap serves as an extra barrier against impact. With the combination of membrane, pre-filter, and protective cap, long-lasting protection is ensured, even after exposure to challenging road conditions.
