The Viega VIEGCAP1 is a ProPress copper pipe cap designed for 1 inch nominal pipe sizes using a press end connection style. This cap is built for professional plumbing and mechanical systems where a secure, leak-free termination is required. It is commonly used by plumbers and pipefitters to permanently seal the end of a copper pipe or tubing run without the need for open-flame soldering or solvent cements. The press connection technology allows technicians to complete installations faster and with fewer steps than traditional sweat-soldered fittings. This makes the VIEGCAP1 a practical choice for tight spaces, occupied buildings, or any job site where open flame is restricted or undesirable. The fitting is rated for pressures up to 200 psi and is suitable for operating temperatures ranging from 0 to 250 degrees Fahrenheit, making it compatible with a wide range of domestic water, hydronic heating, and cooling applications. The cap measures 1.11 inches in length, keeping the overall footprint compact when installed at the end of a pipe. Copper construction provides excellent corrosion resistance and long service life in both hot and cold water systems. Viega ProPress fittings are widely recognized in the trade for their reliability and compatibility with standard press tooling. The VIEGCAP1 fits into existing ProPress system installations without additional adapters. It is a straightforward, code-compliant solution for permanently capping off copper pipe ends in commercial and residential plumbing work. Plumbers working on retrofit projects, new construction, or service repairs will find this cap easy to install and dependable in service.
