DESCRIPTION <br /> The Viking Microfast�' Quick Response Pendent Sprinkler VK302 is a small = ; <br /> thermosensitive glass bulb spray sprinkler available with various finishes � <br /> and temperature ratings to meet design requirements. The special Polyester, 'i <br /> Polytetrafluoroethelyne (PTFE), and Electroless Nickel PTFE (ENT) coatings I <br /> can be used in decorative applications where colors are desired. In addition, , �� <br /> these coatings have been investigated for installation in corrosive atmospheres � <br /> and are listed/approved as corrosion resistant as indicated in the Approval � <br /> Charts. (Note: FM Global approves ENT finish as corrosion resistant. FM <br /> Global has no approval classification for PTFE and Polyester coatings as corro- ' <br /> sion resistant.) �� , � <br /> 2.
