Vent Plugs Stainless Steel IP67 / IP68

Home - Connectivity - Cable Glands, Junction Boxes & Vents - Vent Plugs Stainless Steel IP67 / IP68

IP67 and IP68 breathable vent plugs offer reliable pressure equalisation to prevent condensation inside sealed enclosures. By balancing internal and external pressure, they protect against moisture, corrosion, and short circuits, eliminating the need for costly heating or ventilation systems. Featuring durable, breathable Acrylic copolymer on nylon-support membranes, these solutions enhance safety, extend service life, and reduce maintenance in harsh environments.
  • Housing Material :-Stainless Steel (1.4305/303)
  • IP67 to IP68 protection
  • Available in types that provide ventilation performance from very low to very high levels
  • Prevents the formation of water condensation and protects against damage caused by pressure differences.
  • Designed to provide reliable pressure equalization inside sealed housings and enclosures.
  • Temperature range: -40°C to +100°C
  • Provides ventilation without compromising ingress protection (IP67–IP68).
  • High-performance membranes withstand aggressive environmental exposure.
  • Minimises corrosion and wear inside enclosures, ensuring longer operational life.
  • Reduce servicing costs by keeping electronics performing consistently.
  • Ideal for marine, food & beverage, industrial, and temperature-variable settings.
