Viega 90315 MegaPress coupling 3/4 in bath hardware

SKU CH-SD5Q-CFECN

Connects two 3/4 in pipes with a press-fit stainless steel coupling rated to 200 psi

  • Press-fit installation saves time on potable water lines
  • 316 stainless steel body resists corrosion in plumbing systems
  • EPDM O-ring seals up to 200 psi operating pressure
  • Straight 3/4 in connector joins equal pipe sizes directly
  • No-stop design allows full pipe insertion for secure crimp

Stainless 316 press-fit coupling

The Viega 90315 MegaPress coupling joins two 3/4 in pipes with press-fit connections on both ends. Made from grade 316 stainless steel with an EPDM O-ring, it is rated for potable water at up to 200 psi. The straight connector measures 2 15/16 in overall length and has no stop.

Verify pipe material and press tool access

Confirm the existing pipe is compatible with press-fit stainless fittings and sized at 3/4 in outer diameter. Ensure a suitable press tool and jaw set for 3/4 in stainless press systems is available on site. Check that local codes accept press connections for potable water and that no threading or soldering adapters are required.

Replaces threaded or soldered 3/4 in couplings

This fitting replaces traditional threaded or soldered straight couplings in 3/4 in potable water lines. The jump is worth it when faster, flameless installation is preferred and the system pressure stays within 200 psi. It is not for applications needing a stop feature, flange mounting, or bolt-hole alignment.

Questions about this item

What is included with the Viega 90315 MegaPress coupling and do I need any extra parts?

The box contains the straight press-fit coupling with its EPDM O-rings already fitted. You will need a compatible press tool and stainless-steel tubing cut to 3/4 in outer diameter.

How do I choose the right version of this 3/4 in coupling for my job?

This single model 90315 is a no-stop straight connector in 316 stainless rated to 200 psi; select it when you need a direct press-fit joint between two 3/4 in tubes.

What does the 200 psi rating mean once the coupling is installed in a potable-water system?

It confirms the joint will hold up to 200 psi working pressure in hot or cold potable water when pressed correctly with the proper tool.
