Viega 4815.5XL carbon steel coupling

This carbon steel coupling uses a press-by-press connection for 2-1/2 inch tube. It carries a 200 psi pressure rating and operates from 14 to 284 degrees Fahrenheit. The no-stop design allows full insertion depth during assembly.

Suited for press-fit carbon steel systems

Installers needing a straight coupling for 2-1/2 inch carbon steel pipe with press tooling will find this fitting matches the required standards. Projects that require a built-in stop, different tube material or another connection method should select an alternative fitting.

Fits press-tool workflows on 2-1/2 inch lines

The coupling joins two press-ready ends without additional threading or welding equipment. It satisfies FM, LC1002, PS117, TSSA and UL listings for code compliance. The carbon steel body handles the stated temperature and pressure range in hydronic or compressed-air circuits.

Questions about this item

What size tubing must I already have to connect the 2-1/2 in press ends of the 4815.5XL coupling?

You need 2-1/2 in tubing on both sides; the coupling is a press-by-press fitting for that exact tube size.

Will the carbon-steel body of this 2-1/2 in coupling hold up to the same 200 psi, 284 °F conditions as my existing steel pipe?

Yes, the carbon-steel fitting is rated for 200 psi and a temperature range of 14 to 284 °F, matching typical steel-pipe service limits.

After pressing the 4815.5XL onto 2-1/2 in tube, how can I verify the joint is secure before pressurising to 200 psi?

Visually confirm the press tool jaws fully engaged the fitting bead on both ends, then pressure-test the system per applicable code.
