Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
Stainless Steel Pipe Bleed Rings
 |
 |
Create an access point in a pipe line where corrosion is a concern. Often used to relieve pressure or siphon and sample liquids, these bleed rings act as a port between two pipe flanges, eliminating the need to take apart your flanges to get inside. They include a plug, or replace the plug with your own fitting, valve, or probe. Made of stainless steel, these bleed rings resist rusting.
Install these bleed rings between two pipe flanges along with a gasket on both sides to avoid leaks. They’re designed to fit flanges that meet ASME B16.5.
304/304L Stainless Steel—304 stainless steel bleed rings keep corrosion at bay in wet conditions but will start to corrode when exposed to salt water.
316/316L Stainless Steel—316 stainless steel bleed rings withstand wet conditions as well as chemicals and salt water.

Steel Pipe Bleed Rings
|  |
Access the inside of a pipe line to vent pressure, drain liquid, or take samples. These bleed rings act as a port where two pipe flanges meet, so you don’t have to disassemble your flanges to get inside. They include a plug, or you can attach your own fitting, valve, or probe. Made of steel, these bleed rings should be used in noncorrosive environments to prevent rusting.
Install these bleed rings between two pipe flanges along with a gasket on both sides to avoid leaks. They’re designed to fit flanges that meet ASME B16.5.
