ProPress extended coupling no stop 3/4 in trap

The Viega 79010 is a straight extended coupling for potable water systems. It connects two 3/4 inch copper tubes using press-fit ends on both sides. The fitting is made from copper with an EPDM O-ring and carries no centre stop. It is intended for installers who need a continuous press connection between equal tube sizes.

Thermals noise and power draw in normal use

This component has no moving parts, electrical draw or active cooling. It operates passively within the plumbing network and produces no audible noise. The copper body and EPDM seal are rated for a maximum operating pressure of 200 psi. Thermal behaviour follows the surrounding water temperature and pipe insulation.

Maximum operating pressure 200 psi

The 200 psi rating defines the pressure boundary for this fitting. Systems that exceed this pressure require a different component. Buyers who need a centre stop for tube positioning cannot use this model. The fitting is restricted from sale in certain states, so local code compliance must be verified before purchase.

Questions about this item

How do I install the ProPress extended coupling without a center stop, and what step do installers often miss?

Press the coupling onto both 3/4 in copper tubes using a compatible ProPress tool; the missing step is fully seating each tube end so the EPDM O-rings compress evenly without a stop to gauge depth.

What maintenance or replacement will the EPDM O-ring seals need over time?

The EPDM O-rings should be inspected periodically for hardening or cracking and replaced if leakage appears, as they are the only sealing element in the press-fit joints.

What pressure limit will be reached first during sustained operation?

The fitting is rated for a maximum operating pressure of 200 psi, which is the primary limit under continuous service.
