Straight union valve in brushed stainless steel with press-fit ends

Viega

Viega 90415 straight union valve 1/2 in press-fit stainless 316 EPDM 200 psi

SKU CH-N59X-BNK88

Press-fit stainless 316 straight union joins two 1/2 in pipes with EPDM seal rated to 200 psi

  • Press-fit ends install fast without threading tools
  • Stainless 316 body resists corrosion in potable water
  • EPDM O-ring seals reliably at 200 psi
  • Straight union joins two 1/2 in tubes directly
  • 4 17/32 in length fits tight plumbing runs

Press-fit union for potable water

The Viega 90415 straight union joins two half-inch pipes in potable-water systems. Both ends use a press-fit connection that removes the need for threading or soldering. The fitting body is stainless steel grade 316 with an EPDM O-ring. It is rated for 200 psi maximum operating pressure.

Press ends and EPDM seal change installation

The press-fit design lets installers complete joints with a compatible press tool instead of open flame or pipe dope. EPDM O-ring material resists chlorinated water and common treatment chemicals. No bolt holes or flange surfaces are present, so the union stays compact in tight runs.

Grade 316 stainless body handles 200 psi

Stainless steel grade 316 provides corrosion resistance for long service in aggressive water conditions. The straight-union shape keeps flow path simple and allows easy visual inspection of the joint. Overall length is 4 17/32 in, giving a predictable layout dimension for pipe planning. Builders needing a threaded or flanged connection must choose a different fitting type.

Questions about this item

Does the 316 stainless body or the EPDM O-ring need scheduled replacement?

The 316 stainless body resists corrosion in potable water, while the EPDM O-ring handles normal thermal cycling; neither has a published service interval.

What pressure limit is reached first during continuous 200 psi operation?

The fitting is rated for 200 psi maximum operating pressure, so that pressure ceiling is the limiting factor under sustained use.

How much heat does the 4 17/32 in straight union transfer when water runs all day?

Stainless steel conducts heat, so the 4 17/32 in body will approach water temperature; no insulation is included.
