Screw-in Vent Pressure Tolerance

General Specifications

  • Standard pressure range: 1 to 15 PSI
  • Depends on design, material, and application
  • Varies between plumbing, automotive, and industrial uses
  • Always check manufacturer specifications

Residential Plumbing

  • Primarily for air pressure equalization
  • Handles minimal positive/negative pressure (<5 PSI)
  • Prevents water trap siphoning
  • Not designed for significant pressure

Automotive Applications

  • Higher tolerance than plumbing vents
  • Typically 10-15 PSI
  • Engine crankcase ventilation
  • Pressure varies by vehicle design

Industrial Vents

  • Made from stainless steel or brass
  • Higher pressure ratings (30-50 PSI)
  • Wide variation between models
  • Critical to match system requirements

Always ensure the vent matches system pressure requirements and complies with industry standards.
