Viega MegaPress 4818 carbon steel tee 1-1/4 inch

1-1/4 Inch Carbon Steel Tee

The Viega MegaPress 4818 tee connects three sections of 1-1/4 inch carbon steel pipe in a T configuration. It is intended for commercial plumbing professionals who need to branch existing black, painted or powder-coated steel lines without welding equipment. The press-connect design eliminates open flame and reduces on-site contamination from cutting oil or metal filings.

Cold Press Installation Limits

Cold press technology removes the fire and smoke hazards of welding, yet it requires a compatible press tool and jaws that are not included with the fitting. The zinc-nickel coating resists corrosion on seamless and welded pipe, but the connection cannot be disassembled once pressed. Installers must verify pipe condition and tool calibration before each joint to ensure a leak-free seal.

Upgrade From Threaded Or Welded Joints

This tee replaces traditional threaded or welded fittings when a project demands up to 60 percent faster installation and a cleaner work environment. The jump is worthwhile for repair and expansion jobs on small to large commercial systems where downtime, fire permits or indoor air quality make hot work impractical. It is not suited for applications requiring future disassembly or for piping materials outside the approved steel range.
