Flowflex End Feed Fittings, sizes 8mm to 54mm, manufactured in both copper and bronze, are a fast, reliable and economic method of joining BS EN 1057 copper tube.

End Feed Fittings connect to copper tube through the process of capillary action with solder forming an easy, effective joint between the fitting and the tube.

They are lightweight for easy handling and lend themselves well to confined environments due to their compact sizing.

Approvals

Flowflex operates a quality management system audited by the British Standards Institute for the manufacture and supply of fittings and components for use in all applications of the HVAC industry.

Tube Compatibility

All installers should ensure that the size of the fitting matches the size of the pipe, whilst also ensuring both are in good condition and free from damage and imperfections.

Flowflex fittings are designed to connect to BS EN 1057 tube, for water and gas in sanitary and heating applications.

After all plumbing work has been completed, always ensure continuity checks are conducted by a qualified electrician in accordance with regulations (BS 7671: 20001).

Working Conditions

The working conditions for Flowflex End Feed fittings vary depending on the type of solder or brazing alloys used to join the fittings. Outlined below are alloy mixtures that we recommend using, together with their respective working conditions.

Recommended Soldering Alloys
Tin:Lead - 50:50 or 40:60
Tin:Silver - 95:5
Tin:Copper - Remainder:3>0.4
Recommended Brazing Alloys
Copper:Silver - Remainder:55>40 (Cadmium-Free)
Copper:Silver - Remainder:40>30 (with Cadmium)
Copper:Phospherous - 94:6
Copper:Phospherous:Silver - 92:6:2

NOTE: Soldering alloys with lead and brazing alloys with cadmium are not permitted in installations for water for human consumption.

All working conditions assume that the components have been assembled and connected correctly, and adhere to their respective tube compatiblity
When planning to use our products in applications outside the scope of our recommendations, approval from us should be obtained beforehand. Please contact us in these cases.

Electrical Continuity

Equipotential Bonding forms an important part of an installation, which ensures that all metalwork may be earthed or at least has the same potential to reduce the risk of equipment damage and personal injury. Isolated fittings or valves are not required to be bonded.

After all plumbing work has been completed, always ensure continuity checks are conducted by a qualified electrician in accordance with your applicable regulations.
