The 2" Justrite self- closing safety Drum Gate Valves body is made of brass and features a Teflon seal. The Drum Gate Valve model screws tightly into drum and can then be adjusted to right position, with spout downward, without thread damage or leakage. For trouble-free dispensing of viscous noncorrosive flammables such as adhesives, paint or heavy oils above 2000 SSU (about 30W oil), the 2" Justrite Drum Valve is ideal.
