Stainless Steel Bleed Rings
Stainless steel bleed rings in 1" to 24" sizes for Class 150, 300 and 600 flanges, with a threaded radial port for bleeding, draining, venting and instrument connections.
About Stainless Steel Bleed Rings
Trilogy stainless steel bleed rings install between two flanges to add a connection point at the flange joint. The radial port lets operators bleed, drain or vent the line, and provides a place to mount gauges and other instruments without modifying the pipe or valve.
Rings are machined from solid stainless steel and sized to standard flange dimensions from 1" through 24" in Class 150, 300 and 600.
