Copper press-fit cap for 3-inch tube

The Viega 20843 is a copper cap designed to terminate a 3-inch press-fit plumbing line. It connects directly to compatible copper tube using a press tool, forming a permanent seal without solder or flame. The fitting carries an EPDM O-ring and meets multiple North American plumbing and fire-protection standards.

Replaces soldered or threaded end caps

This cap removes the need for open-flame soldering, flux, or pipe dope on a 3-inch line. The jump is worth it when installation speed, fire-safety restrictions, or limited workspace make a press connection the only practical way to close the system.

Rated for 200 psi and 250 °F maximum

The fitting handles potable-water pressure up to 200 psi and continuous temperatures up to 250 °F, with a minimum operating temperature of 0 °F. It is not intended for service beyond those limits or for applications that require a centre stop inside the cap.
