Wednesday, July 24, 2019 - 8am


Hastings, Michigan, USA – The Viking Corporation, a global leader in fire protection and life safety systems, has introduced a stainless steel sprinkler with a fusible link operating element – the first of its kind in the fire protection industry. The new Model VK368 is a standard response pendent sprinkler and is cULus Listed and FM Approved for corrosive environments.

The Model VK368 features a stainless steel sprinkler body, deflector, and seat. With a solder link operating element, the sprinklers are especially well-suited for food processing facilities where exposure to glass may be a concern. Available with an intermediate temperature rating of 205°F (96°C), the 8.0 (115) K-factor Model VK368 has a 3/4” NPT thread and uses a standard sprinkler installation wrench. Versions with a 161°F (72°C) temperature rating and 20 mm BSPT options will be available at a later date.

The new stainless steel sprinkler joins Viking’s wide selection of corrosion-resistant sprinkler options including "Electroless Nickel PTFE" (ENT) plated sprinklers, which are available throughout a significant portion of the Viking sprinkler product line. Additionally, stainless steel flat cover plates are available for Viking’s Mirage® Model VK462 and Model VK538 Concealed Pendent sprinklers, and the Freedom® Model VK494 Residential Concealed Pendent sprinkler.
