Copper Adapter Flange 4 in

The Viega ProPress 0959.5XL is a copper adapter flange designed for potable water systems. It connects a 4 in copper tube via press-fit on one side to a flange on the other. The fitting meets ASTM B75 and ASTM B88 standards for material quality.

Sustained pressure and temperature rating

The assembly is rated for a maximum operating pressure of 200 psi and a maximum operating temperature of 250 degrees F. These limits define safe continuous service rather than short-term burst capacity. The EPDM O-ring material supports this temperature range in potable water applications.

Press-fit connection requirement

Installation requires a compatible Viega press tool to create the permanent seal on the 4 in copper tube side. The fitting cannot be joined with solder, thread or push-fit methods. Buyers without access to the specified press tool cannot install this part.

Questions about this item

How much heat can the Viega ProPress 0959.5XL adapter flange handle in continuous hot-water service?

The copper body and EPDM O-ring are rated for a maximum operating temperature of 250 Degrees F, so the fitting remains sealed in sustained high-temperature potable-water lines.

Which press tool and jaw set are required to install the 4 in press-fit end of this flange?

The fitting is compatible with Viega press tools; you must already own a Viega press tool and the correct 4 in jaw or ring for the ProPress system to make a watertight crimp.

Will the 4 in press connection on this flange mate with existing Type K or Type L copper tube already in the building?

Yes, the press-fit side is sized for 4 in copper tube that meets ASTM B75 and ASTM B88, the standards covering both Type K and Type L hard-drawn copper water tube.
