Air Vent Cap End Feed - 15Mm

AIR VENT CAP 15MM EF

The Copper End Feed Air Vent Cap (15mm) is a specialised fitting used in traditional copper central heating systems. It is designed to create a secure, soldered termination on a 15mm pipe riser, specifically where an automatic or manual air vent valve is to be installed to release trapped air from the system.

Key Features and Installation Details
Compliance: Manufactured to high standards (e.g., BS EN 1254) and typically WRAS Approved if intended for potable water systems, ensuring reliability in central heating applications.

Material: Constructed from durable Copper, providing a permanent, high-integrity base for the air vent.

Configuration: This is a terminal fitting. The 15mm End Feed Port connects permanently to the pipe riser, and the opposing end features a threaded socket (usually 1/2" BSP Female) specifically sized to accept a standard air vent.

Size: Connects to a 15mm copper pipe. The threaded side is designed to receive an air vent (air eliminator).

Function: Used at the highest point of a central heating circuit (e.g., a high-level radiator or cylinder coil pipework) to trap and vent air, preventing airlocks, noise, and corrosion within the system.

Installation Method: End Feed – Requires heating with a blowtorch, and the application of flux and solder to achieve a permanent capillary seal to the 15mm pipe.

The Installer's Advantage
Using a dedicated air vent cap provides a professional and secure termination point for the air vent, ensuring it is correctly positioned and permanently sealed to the pipework. This eliminates the need for complex adaptors or multi-fitting assemblies to transition the pipe to the vent thread, simplifying installation at critical high points.

Essential Companion Products (Copper System)
To successfully create a permanent, leak-proof soldered joint and complete the setup, the following linked materials are required:

Pipe: Requires 15mm pipe for the riser connection: Copper Tube 15mm x 0.7mm x 3m

Flux: Essential for preparing the surfaces for soldering: LA-CO Soldering Flux 60g

Solder: Required to complete the high-integrity seal: Lead-Free Solder 250g

Cleaning: Required for preparing pipe ends before fluxing: Steel Wool Pack (6oz)
