Hep2O® - Connection to Metric Copper Pipe

Connection to Metric Copper Pipe

Hep2O® fittings have been designed to form reliable joints with metric copper tube which conforms to BS EN 1057 - R520. Copper pipes should be cut with a wheel cutter. Before jointing, copper pipe ends should be inspected to ensure they are free from burrs or swarf (which could damage the 'O' ring). It is also possible to connect 10mm BS EN 1057 - R220 copper tube into Hep2O® fittings providing the tube end is carefully prepared.

R220 copper tube is 'soft' and therefore susceptible to becoming misshaped or dented if it is not handled with care on site. Therefore the R220 tube end should be inspected for any signs of damage prior to jointing, as deformity of the tube could damage the 'O' ring whilst jointing, or otherwise affect the joint seal. R220 tube should be cut with a mini wheel cutter, and then a chamfer should be filed on the pipe. Rinse away the remainder of any copper filings and dry-off.

NB: Mark the joint depth on the copper pipe before jointing.
