VK503 - ESFR Pendent Sprinkler (K16.8)

VK503

Viking is a proud world leader in the design and manufacturing of life-saving fire sprinklers. The VK503 ESFR Pendent Sprinkler is just one of thousands of industry-leading sprinklers available to customers! 

The VK503 is a fast response fusible element type sprinkler designed for early fire suppression. With a 16.8 (242 metric) nominal K-Factor and special deflector, this sprinkler produces large, high-momentum water droplets in a hemispheric pattern below the deflector. This permits penetration of the fire plume and direct wetting of the burning fuel surface while cooling the atmosphere early in the development of a high-challenge fire.

Sift through virtually every sprinkler in a flash with the revolutionary Sprinkler Selector(opens in a new window)! Select various criteria, such as K-factor, occupancy type, orientation, temperature and more, to get the part number you need. Test it out today and streamline your projects!
