MegaPress union for carbon-steel pipe

The Viega 25715 MegaPress union joins two 1-1/4 in carbon-steel pipe ends using a press-to-press connection that requires no threading or welding. It is intended for installers who need a permanent, leak-tight joint in hydronic or compressed-air systems where open-flame work is impractical.

Rated for 200 psi and 0 to 250 °F

The carbon-steel body withstands a maximum working pressure of 200 psi across the full temperature range of 0 to 250 degrees Fahrenheit. Pressed joints maintain their seal through thermal cycling without the loosening that can affect threaded fittings.

No additional components required

The fitting arrives ready to press; no gaskets, sealant, thread tape or separate ferrules are needed. A compatible press tool and jaw set complete the installation, reducing the number of parts a technician must carry to the job site.

Questions about this item

How is the Viega 25715 MegaPress union installed and what step is often missed?

Install by pressing each end with a compatible MegaPress jaw on a press tool; the step often missed is verifying the press indicator ring on both connections to confirm a complete seal.

What maintenance or replacement will the MegaPress union need later?

The carbon steel body with press connections is designed for permanent installation; no routine maintenance is required, but inspect for corrosion if system water chemistry exceeds recommended limits.

What limit appears first on the MegaPress union under sustained high-temperature use?

The temperature rating of 250 degrees F is reached before the 200 psi pressure rating under sustained heat, so thermal limits govern continuous operation.
