Stainless steel press-fit coupling with centre stop

Viega

Viega 95285 MegaPress coupling 1/2" press-fit 304 stainless 200 psi

SKU CH-7S9S-QD246

A 1/2" press-fit stainless-steel coupling with a rolled centre stop, rated to 200 psi for non-potable water

  • Press-fit installation saves time on non-potable lines
  • 304 stainless body resists corrosion in harsh environments
  • FKM O-ring handles 200 psi operating pressure
  • Rolled center stop ensures correct insertion depth
  • 2 23/32 in overall length fits tight spaces

1/2" Stainless Press Coupling

The Viega 95285 MegaPress coupling joins two 1/2 inch pipes with a press-fit connection. It is manufactured from 304 grade stainless steel and features an FKM O-ring. A rolled centre stop ensures correct insertion depth on both ends. The fitting is rated for a maximum operating pressure of 200 psi.

Non-Potable Systems Only

This coupling is designed for non-potable water applications such as hydronic heating or compressed air lines. It is not certified for drinking water installations. Installers without access to a compatible press tool cannot use this fitting. Projects requiring threaded, soldered or push-fit connections need a different fitting type.

200 psi Pressure Rating

The 200 psi maximum operating pressure determines whether this coupling suits the system design. Verify that the intended application does not exceed this limit. The 304 stainless construction and FKM seal define the chemical and temperature compatibility. No other fitting in this range carries a higher pressure rating from the supplied data.

Questions about this item

How do I press the 1/2" MegaPress coupling onto the pipe and what step is often missed?

Cut the pipe square, deburr inside and out, check the FKM O-ring is seated, mark the 2 23/32 in insertion depth, then press with a calibrated MegaPress jaw; the step often missed is verifying the depth mark after pressing.

What maintenance will the FKM O-ring in this 304 stainless coupling need over time?

Inspect the FKM O-ring annually for hardening or chemical attack from non-potable water; replace the O-ring if it shows cracks or permanent compression set, otherwise the 304 stainless body requires no routine maintenance.

At what pressure does the 200 psi rating become the limiting factor during sustained operation?

The 200 psi maximum operating pressure is the first limit reached under sustained use; continuous pressure above this value will stress the FKM seal and rolled centre stop beyond their design allowance.
