Viega MegaPress 4815.5 Coupling 3/4 Carbon Steel

This Viega MegaPress coupling is a 3/4 inch carbon steel fitting designed for joining pipes without an internal stop. It suits professionals working on repair or expansion of existing steel pipe installations in commercial projects. The zinc-nickel coating provides corrosion resistance for black, painted or powder-coated pipe.

Cold Press Installation Without Welding

Cold press technology eliminates the need for welding, removing smoke and fire risk on the job site. Connections are clean and free from thread cutting oil or metal filings. Installation time can be reduced by up to 60% compared to traditional welded connections. The no-stop design allows the coupling to slide fully over the pipe for flexible positioning.

Check Pipe Compatibility Before Ordering

Verify that the existing pipe is 3/4 inch carbon steel, either seamless or welded, and that the surface is black, painted or powder-coated. Ensure a compatible MegaPress press tool and jaws are available for the 3/4 inch size. This coupling is not intended for other pipe materials or diameters.

Questions about this item

How can I confirm the MegaPress 4815.5 coupling is working correctly after pressing?

A successful press creates a permanent, leak-free joint on black, painted or powder-coated steel pipe; the connection is clean with no thread-cutting oil or metal filings and the zinc-nickel coating remains intact for corrosion resistance.

What comes in the box and what extra items are required to install this coupling?

The box contains the 3/4" carbon steel MegaPress coupling without stop; you must supply compatible steel pipe (seamless or welded) and a MegaPress press tool with the correct jaw set to complete the cold-press connection.

When should I choose the no-stop version 4815.5 instead of a stop coupling for my 3/4" line?

Select the no-stop 4815.5 when you need the coupling to slide fully over the pipe for repairs or inline expansion, allowing full insertion on both ends before pressing.
