In each of its UL Listed areas of coverage, it provides the lowest flow rates available in the industry. The optional Electroless Nickel PTFE (ENT) coating has been investigated for installation in corrosive atmospheres and is UL Listed as corrosion resistant.
The VK486 is compatible with revolutionary InstaSeal® technology through the addition of new Torque-Assist caps. Make sure to look for the compatibility icon to ensure the correct sprinklers are being ordered for a job requiring InstaSeal technology.
