  • Press-fit installation eliminates threading tools

  • EPDM O-ring seals without solder or flux
  • Rolled centre stop ensures correct insertion depth
  • 2 23/32 in overall length fits tight spaces

Stainless 316 Press-Fit Coupling

This Viega Megapress coupling joins two half-inch tubes in potable-water systems. The 316-grade stainless body resists corrosion in aggressive water conditions. A rolled centre stop ensures each tube seats at the correct depth without measurement. Model 90285 is supplied new and ready for press installation.

Press-Fit Connections with EPDM Seal

Both ends use a press-fit profile that eliminates threading, soldering or adhesive. The EPDM O-ring provides a watertight seal once the joint is pressed. Straight connector geometry keeps the run linear, simplifying layout in tight chases. No bolt holes or flanges are present, reducing potential leak paths.

Replaces Threaded or Soldered Half-Inch Unions

Installers moving from threaded brass or copper sweat joints gain speed and avoid open flame. The press method is worth the switch when labour savings outweigh fitting cost. Not suited for systems requiring larger diameters, flanged connections or non-potable fluids. Buyers needing alternative tube sizes or configurations must select a different fitting.

Questions about this item

What pipe sizes does the 1/2" press-fit coupling connect?

It joins two 1/2 in tubes on both ends using a straight press-fit connection.

What overall length must the installation allow for this coupling?

The fitting measures 2 23/32 in from end to end, so the pipe run needs that clearance.

How is the coupling installed and which step is often missed?

Press the fitting onto each tube with a compatible press tool; forgetting to verify the rolled center stop is seated can leave the joint misaligned.
