Propress
General
Press connector system with press connectors that use modern cold press connection technology in dimensions ranging from DN 15(1/2”) to DN 100(4”). Copper tube: type A, B and C hard drawn copper tube from DN15 to DN100 and annealed copper tube in DN15 to DN40. All tube must comply with the AS 1432 standard. Propress fittings are approved for installations in both above and below ground applications.
Press Connectors All sizes with SC‑Contur (Smart Connect) – connections which remain unpressed become visible when the system is filled. During leakage tests with water, Viega guarantees the identification of unpressed connections in the pressure range 100‑650 kPa, in the case of a dry leakage test with compressed air or noble gases from 2.2‑300 kPa.
