Overview

Donaldson screw-fit vents are designed for easy integration and long-term protection. They block liquids, dust, and harmful particles while allowing continuous pressure and temperature equalization, essential during altitude or thermal changes. The durable threaded design fits seamlessly into your equipment, helping extend enclosure life and improve reliability. With consistent airflow and rugged sealing, our screw-fit vents are designed for maintaining performance in tough environments

Features

  • Robust design provides maximum protection from harsh environments
  • Hydrophobic vent meets water repellency ratings up to IP69K
  • Oleophobic vent meets oil repellency ratings up to 8
  • Provides dust and liquid protection while equalizing pressure
  • Screw-Fit design integrates easily into your device for quick assembly
  • Secure vent cap design will not separate from the body during installation or application
  • Durable automotive-grade glass-filled PBT plastic provides high strength and resistance to harsh environment

Handling & Specification

  • Clean mounting surface and area where Screw-Fit vent will be installed to remove any contamination
  • Allow surface to dry after cleaning
  • Ideal location for installation is on a flat, vertical surface on an exterior housing wall. This location will prevent any liquids from collecting
  • Insert the Screw-Fit vent into the housing with the threads aligned properly and screw into the housing
  • After ensuring that the vent is threaded properly, tighten the vent to 0.6 - 1.0 Nm (5-10 in-lb)
  • Optional hex nut (P516960) is available for M12x1.5 Screw-Fit vents
  • Chamfer recommended for optimal O-Ring seal when wall thickness is suitable
