Type A compression fittings are:

• Non-manipulative fittings, used on high pressure systems

• Manipulative fittings, used on lower pressured systems

• Non-manipulative fittings, used on lower pressured systems

• Manipulative fittings, used on high pressure systems

To prepare the pipework for the type B compression fittings, you must:

• use a swaging tool on the ends of the pipework.

• apply flux to the ends of the pipework.

• apply solvent weld to the ends of the pipework.

• make sure the o rings are not damaged.

If a compression fitting has the mark DZR stamped on it, it means the fitting is:

• Lead free

• A direct zone reducing valve

• Dezincification resistant
