DESCRIPTION <br /> The Viking Microfast� Quick Response Pendent Sprinkler VK302 is a small e°r <br /> thermosensitive glass bulb spray sprinkler available with various finishes <br /> and temperature ratings to meet design requirements. The special Polyester, <br /> Polytetrafluoroethelyne (PTFE), and Electroless Nickel PTFE (ENT) coatings <br /> can be used in decorative applications where colors are desired. In addition, ,Lt <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.
