About this category

DZR solar thermal compression couplings are manufactured to offer dezincification ISO 6509 laboratory standards. The DZR logo means that the fittings are manufactured with a high percentage of zinc which is highly resistant to corrosion. The corrosion is inherent with solar thermal systems were the glycol fluid can eat its way through less zinc incorporated material parts. We offer many variations of these DZR fittings to help plumbers and engineers to commission any glycol filled pressurized heating system quickly and efficiently. This is without the risk of bursting brass fitting while putting the high pressures through solar thermal system equipment. Tolerances can be increased with the use of our high pressure copper tube inserts. Use the best products available when repairing or assembling solar thermal hot water copper pipe work compression connections. Material specification meets with EN2154-2 DZR high temperature and corrosion resistant joints.
