Stainless 316 Press-Fit Tee

The Viega Megapress 90185 is a crimp tee fitting made from grade 316 stainless steel for potable water systems. It provides three 3/4-inch connections with press-fit ends on two sides and a female pipe thread on the third. An EPDM O-ring seals each press joint without soldering or threading the pipe.

Upgrade from threaded or soldered tees

This fitting replaces traditional threaded or sweat connections where faster installation and corrosion resistance are priorities. The press-fit design eliminates open flame and reduces labour time on site. The jump is worth it on projects that demand 316-grade stainless durability and a 200 psi pressure rating.

Sustained pressure and temperature performance

The assembly is rated for continuous operation at 200 psi and temperatures up to 250 degrees F. Grade 316 stainless steel resists scaling and chemical attack over long service periods. The EPDM seals maintain integrity through thermal cycles without the degradation seen in lower-grade alloys.

Questions about this item

What pipe size and connection types does the 3/4" Megapress tee require for each port?

The tee accepts 3/4" tube on all three ports; ports A and B are press-fit connections and port C is a 3/4" FPT thread.

Which press tool and jaw size are used to install the 316 stainless tee, and what common step is missed?

Use a Viega-approved press tool with the correct 3/4" jaw; the step often missed is verifying the press indicator ring is fully closed before pressurising.

When should the EPDM O-rings in the 90185 tee be inspected or replaced?

Inspect the EPDM seals during any system service or if leakage appears; replace them if they show hardening, cracking or permanent deformation after prolonged exposure to 250 °F water.
