High-Pressure Steel Bleed Rings
- For Use With: Air, Natural Gas, Oil, Steam, Water
- Pressure Class: See table
- Flanges:
Pressure Class 300: Use Class 300 steel
Pressure Class 600: Use Class 600 steel
Tap into 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. Remove the included plug for access or attach your own fitting, valve, or probe to the threaded hole. Made of black-coated 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.

To relieve pressure, siphon liquid, or take samples in a pipe line where corrosion is a concern, these bleed rings act as a port between two pipe flanges. They have a threaded hole and plug to access the inside of your line instead of having to disassemble your flanges. Or remove the plug and attach your own fitting, valve, or probe. These bleed rings are stainless steel, so they 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 stainless steel bleed rings keep corrosion at bay in wet conditions but will start to corrode when exposed to salt water. 316 stainless steel bleed rings withstand wet conditions as well as chemicals and salt water.

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.

Drainage Valves
Also known as stop cocks, install these valves on your tank for easy draining.
Valves with external seal are for higher flow applications than valves with an internal seal.

Self-Draining Breather Vents
Minimize moisture buildup in enclosures. Also known as drain plugs, these breather vents have a small outlet that allows condensation to drain. They have a silicone O-ring above the threads for a tight seal. Install them at the lowest point of the enclosure. Breather vents meet IP66 for protection in washdown environments. Use them to prevent excess vacuum and pressure in cylinders, gear boxes, and tanks and to block debris from entering equipment.
Brass breather vents have good corrosion resistance.
316 stainless steel breather vents have excellent corrosion resistance.
