Monday, October 2, 2023 - 12pm

Hastings, Mich.– The Viking Corporation announced today a new sprinkler to round out its robust residential concealed sprinkler offering. The cULus Listed VK495 K3.7 Residential Concealed Pendent provides sprinkler designers more options than ever before when dealing with the variability in water supplies seen in residential sprinkler systems.

“The low-flowing K3.7 sprinkler is optimized at the 14’ x 14’ coverage area flowing only 10 gpm at 7.3 psi,” states Darren Palmieri, Viking’s General Manager – Residential Portfolio. “The K3.7 fills out our residential concealed pendent line perfectly, as we already offer a K3.0, K4.9 and K5.8. We now offer concealed sprinklers that are optimized for all the most commonly used coverage areas, making Viking a one-stop-shop for sprinkler designers.”

Viking’s glass bulb VK495 is available in brass or an Electroless Nickel PTFE (ENT) coating for applications in which corrosion might be of concern. The sprinkler is cULus Listed and has an Ordinary temperature rating of 155°F (68°C) and an Intermediate temperature rating of 200°F (93°C). Its protective cap prevents damage to the sprinkler during installation and ceiling finishing, and Viking’s line of cover plates offers multiple sizes, finishes and shapes.
