Copper Press-fit Cap 2 1/2 in

The Viega 20833 is a copper press-fit cap designed to terminate a 2 1/2 inch copper tube in potable water systems. It uses a press-fit connection with an EPDM O-ring to create a watertight seal without soldering. The fitting is listed to multiple standards including CRN, CSA, FM, IAPMO, ICC, NFPA 13D, NFPA 13R, NSF/ANSI 372, NSF/ANSI 61, PHCC, and UL. It suits plumbers and contractors working on commercial or residential water lines.

Replaces soldered caps on copper tube

This cap replaces traditional soldered end caps on 2 1/2 inch copper tube, removing the need for open flame, flux, and solder on the job site. The jump is worth it when installation speed matters, when fire permits are difficult, or when working in tight spaces where torch use is unsafe. It is not for buyers who need a threaded connection, a different tube size, or a fitting rated above 200 psi maximum operating pressure.

Press-tool installation with minimal error points

Installation requires a compatible press tool and jaw set for 2 1/2 inch copper press fittings; the pipe is cut square, deburred, marked for insertion depth, and pressed in a single action. What usually goes wrong: skipping the deburring step damages the EPDM O-ring, an unmarked insertion depth leads to an incomplete press, and using the wrong jaw size produces a leak path. The fitting operates from 0 to 250 degrees F.

Questions about this item

What copper tube size does the 20833 press-fit cap fit?

It fits copper tube size 2 1/2 in and has an overall length of 2 1/8 in with an EPDM O-ring for sealing

Which press tool jaw profile is required for the 20833 cap, and what step is often missed?

Use a Viega-compatible press tool with the correct jaw for 2 1/2 in copper; the step often missed is fully inserting the tube until it contacts the fitting shoulder before pressing

How often should the EPDM O-ring on the 20833 cap be inspected or replaced?

Inspect the EPDM O-ring during any system maintenance or pressure test; replace it if signs of cracking, hardening, or leakage appear, especially after exposure near the 250 Degrees F maximum temperature
