Viega Megapress Stainless 304 Coupling No Stop 1/2" x 1/2" 95310

SKU CH-3543-HRV9Y

Connects two 1/2" pipes with a press-fit stainless steel 304 coupling rated for 200 psi and 250°F

  • Press-fit coupling joins 1/2 in tubes without welding
  • Stainless 304 body resists corrosion in non-potable systems
  • FKM O-ring seals up to 200 psi and 250 Degrees F
  • Straight connector design simplifies in-line installations
  • Ready-to-press fitting cuts labour time on site

Stainless 304 press-fit coupling

The Viega Megapress 95310 is a straight connector made from grade 304 stainless steel. It joins two 1/2 inch tubes with press-fit ends and an FKM O-ring for a secure, leak-free seal. No-stop design allows the fitting to slide fully over both pipes before pressing. Rated for 200 psi and 250 Degrees F in non-potable water systems.

Installers needing a permanent, flameless joint

Suits contractors who want fast, reliable connections without soldering or threading on site. The press-fit method reduces installation time and eliminates open flame hazards. Not intended for potable water lines or applications exceeding the stated pressure and temperature limits. Builders requiring a removable or threaded union should select a different fitting style.

Consistent performance under continuous pressure

The FKM O-ring maintains its seal during sustained operation at the maximum 200 psi rating. Stainless 304 construction resists corrosion and scaling when exposed to non-potable water at temperatures up to 250 Degrees F. The rigid, no-stop body prevents joint movement or creep during long-term thermal cycling. No internal components to fatigue, so the connection remains stable throughout the system lifecycle.

Questions about this item

What press tool and jaw size are needed to install this 1/2" Megapress coupling?

Use a Viega Megapress press tool with the 1/2" stainless steel jaw set to crimp the FKM O-ring connections on both ends.

Can this 304 stainless coupling join directly to existing carbon steel pipe in a non-potable system?

No, the press-fit ends require 1/2" stainless tube; a transition adapter is needed to connect carbon steel pipe.

How can I confirm the 200 psi seal is holding after pressing the coupling?

Pressurise the line to the system test pressure and inspect the two press-fit joints for leaks; the FKM O-rings should show no weeping at 250 °F max.
