Viega introduces PEX Press fire protection fittings and mounting bracket in high-performance polymer for NFPA 13D fire sprinkler installations. Eight new fittings are available in two sizes (3/4” and 1”) and in four configurations (straight adapters, elbows, tees and wall tees). The mounting bracket can be used with all sprinkler pendant styles and every sprinkler configuration. The wall tee fitting does not require a bracket and is designed for applications to efficiently feed back-to-back rooms with one plumbing line and one fitting. Viega.
