Viega 78252 1 Inch Epdm Sealing Element

Product Description

The VIEGA 78252 is a 1-inch EPDM sealing element designed for use in press-fit piping systems. EPDM (ethylene propylene diene monomer) elastomer provides reliable sealing performance across a range of temperatures and pressures commonly encountered in plumbing and mechanical systems. The stainless steel construction of the fitting body complements the EPDM seal material, offering corrosion resistance in demanding installation environments. Licensed plumbers and pipefitters install this component as part of press-connection assemblies, where a watertight, consistent seal is critical to system integrity.

This sealing element is suited for residential and light commercial plumbing applications where press-fit technology is specified. It is used in hydronic heating, potable water distribution, and general mechanical piping systems that require a dependable elastomeric seal at 1-inch connections. Press-fit systems using EPDM seals are commonly found in new construction and retrofit projects where open-flame soldering is restricted or undesirable.

Key Features

• 1-inch nominal size fits standard press-fit connection points
• EPDM elastomer seal material offers resistance to heat, water, and weathering
• Stainless steel construction provides corrosion resistance
• Designed for press-fit piping assembly without soldering or threading
• Consistent seal geometry supports repeatable, leak-free connections

Compatibility

Designed as an OEM-style replacement sealing element for 1-inch press-fit piping system components.

Installation Notes

Installation is performed by licensed plumbers using approved press-fit tooling. Shut off and depressurize the water supply before servicing any piping connection. Inspect the sealing element for nicks or deformation prior to pressing, as damage to the EPDM seal can compromise the joint. Follow applicable IPC and local plumbing code requirements for press-fit assembly and inspection.
