Viega 95390 Press-fit Cap 1/2 in Stainless Steel 304

SKU CH-A4G1-0W474

A press-fit stainless steel 304 cap for 1/2 in potable water lines, rated to 200 psi and 250 °F

  • Press-fit design enables fast, tool-free installation on 1/2 in piping
  • Stainless steel 304 construction resists corrosion in potable water systems
  • FKM O-ring provides reliable sealing up to 200 psi operating pressure
  • Rated for temperatures from 0 to 250 degrees F across hot and cold lines
  • Meets ASTM A312 and ASME B31 piping standards for code compliance

Viega Press-fit Cap 1/2 in

The Viega 95390 is a stainless steel press-fit cap designed to terminate 1/2 inch piping in potable water systems. It provides a permanent mechanical seal without soldering, threading or welding. Installers working to ASTM A312 and ASME B31 standards use it for pressure-tested closures.

FKM O-ring and centre-stop omission

The fitting ships with an FKM O-ring rated for 0 to 250 degrees F and 200 psi maximum operating pressure. Because no centre stop is included, the pipe can be fully inserted through the cap for custom-length assemblies or inspection access. The press profile creates a leak-tight joint in a single tool actuation.

Grade 304 stainless steel construction

Grade 304 stainless steel resists corrosion in chlorinated potable water and withstands the listed temperature range without degradation. The 2 5/32 inch overall length fits tight cavities while leaving enough grip area for press jaws. The press-fit connection eliminates open flame on site and reduces installation time compared to threaded alternatives.

Questions about this item

Will the FKM O-ring need replacement after years of 250 °F service?

The FKM O-ring is rated to 250 °F maximum operating temperature; prolonged exposure near that limit can accelerate ageing, so plan periodic inspection and replacement if sealing performance drops.

What pressure limit governs sustained operation on a 1/2 in press-fit line?

The fitting is rated for 200 psi maximum operating pressure; that pressure ceiling will be reached before any dimensional limit on the 1/2 in pipe.

How much heat does the stainless 304 body radiate during all-day hot-water circulation?

Stainless steel 304 conducts heat modestly; at 250 °F water temperature the cap surface will approach fluid temperature, so insulate the run if personnel contact or heat loss is a concern.
