Air Vents

Air Vents – End Feed Fittings are plumbing components designed to remove trapped air from heating and water systems, using an end feed connection for a secure and compact installation.

About Air Vents – End Feed Fittings

End feed air vents are used to release built-up air from pipework, radiators, and heating systems, helping to maintain system efficiency and prevent issues such as noisy pipes, slow heating, or corrosion. These vents are soldered onto copper pipe systems using end feed technology, creating a permanent, leak-free connection.

They are ideal for sealed systems and are often positioned at high points where air naturally collects. Suitable for both domestic and commercial applications.

Benefits

  • Improves system efficiency: Removes trapped air to enhance heat distribution and performance.
  • Reduces noise: Prevents gurgling or knocking in pipework.
  • Prevents corrosion: Eliminating air helps protect system components.
  • Compact solder fitting: End feed design allows space-saving installation.
  • Long-lasting: Provides a durable joint when installed correctly.

Applications

  • Central heating systems (radiators, pipework).
  • Hot water distribution systems.
  • Boiler and plant room pipework.
  • Commercial heating installations.
  • Solar water heating systems.

Key Features

  • Designed to automatically or manually release trapped air.
  • Suitable for copper pipe installation via soldering.
  • Made from brass or nickel-plated materials.
  • Compatible with high temperature and pressure systems.
  • Available in various sizes (typically 15mm, 22mm, etc.).
  • Compliant with WRAS and BS EN standards (where applicable).

Installation & Technical Info

End feed air vents should be installed at system high points. Clean fitting and pipe, apply flux, solder appropriately, and test after cooling.

Ensure compatibility with operating pressures and temperatures. For sealed or pressurised systems, use vents rated for system specifications.
