Press fitting technology is sweeping the nation and Viega is leading the trend. When Viega introduced the ProPress System to the United States in 1999, installers could stop sweating fittings and start saving time. Today, after millions of trouble-free connections, installers across the county have put down their torches in favor of Viega’s flameless, solderless, ProPress System. Viega’s ProPress System has helped installers across the nation reduce installation time, save money and increase reliability on the job site.
