The leading cause of PRD failures remains water and ice damage, despite years of attempts to bring this to light in the industry. As a reliable solution, Emcara has developed a line of stainless-steel spring-loaded Vent Caps.
Emcara Garter Series Vent Caps are the most effective way of preventing water and foreign material from entering a CNG or Hydrogen PRD system. Utilizing stainless steel construction, Emcara Garter Vent Caps are built to last and are resistant to pressure washing and impact. Our Vent Caps are designed to vent gas and reseal, eliminating the possibility of the vent tube and PRD system becoming contaminated, even if a small amount of gas has vented.
