Viega 95295 MegaPress coupling With stop Smart Connect technology 304 stainless steel, 1'' x 1''

The Viega 95295 MegaPress coupling is a 1 inch by 1 inch fitting, so it joins two runs of 1 inch pipe. Both ends are press connections (P1 x P2), so no threading, welding or soldering is needed at either end.

A coupling with stop has an internal shoulder in the middle of the body, so each pipe end bottoms out at a fixed insertion depth. That sets the engagement for you on both sides. It is the version to use when you are joining two fixed pipe ends and want a repeatable stab depth; a stopless coupling is what you reach for instead when you need to slide the fitting along an existing pipe to close a gap in a run you cannot pull apart.

It is a straight two-end coupling, 1 inch to 1 inch, with a press connection on each end. If you need to branch a 1 inch line, a coupling will not do it; you want a MegaPress tee instead.

Only if you can get both pipe ends into the fitting. Because this coupling has an internal stop, each end seats at a set depth and the fitting cannot be slid along the pipe. For an in-place repair where the pipe cannot be sprung or pulled, use a stopless (no-stop) MegaPress coupling of the same 1 inch size.

The 95295 body is 304 stainless steel. That makes it the choice where carbon steel press fittings would be attacked, such as damp or washdown areas and services where corrosion resistance matters. Note that the sealing element, not the body alloy, governs which media and temperatures a MegaPress fitting is approved for, so match the fitting series to the service you are running.

The fitting itself is 3.366 inches long and 1.78 inches across in both height and width, so plan on clearance beyond that for the press jaw to wrap the collar. In tight bays and close-to-wall runs, measure the jaw envelope of your press tool, not just the fitting.

Smart Connect is Viega's feature that deliberately lets a small amount of water or air past an unpressed fitting during system test, so an un-pressed joint shows itself before the system goes into service. On a 1 inch 304 stainless 95295 coupling that is your pressure-test check: anything weeping at the collar did not get pressed.
