High-quality materials are crucial for optimal sealing performance:

• Vent body: Stainless steel or engineering plastics with excellent corrosion resistance
• Sealing components: O-rings made of EPDM (ethylene-propylene-diene-monomer) or Viton
• EPDM offers good resistance to water and weather
• Viton is suitable for more aggressive chemicals

Key installation requirements:

• Threads must be clean and free of debris
• Torque to recommended value - avoid over/under tightening
• Over-tightening may damage threads or seals
• Under-tightening leads to leakage

Regular maintenance ensures long-term performance:

• Periodically check for wear, cracks, or deformation
• Replace worn-out seals promptly
• Focus on material quality, correct installation, and routine upkeep
