Breather Vents
Protect against excess vacuum and pressure in cylinders, gear boxes, enclosures, manifolds, and tanks. You can also use these breather vents to block debris from entering equipment.
Style H has a Buna-N O-ring for extra protection against leaks.

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.

Mufflers
Use these mufflers with air-powered tools, valves, and cylinders to reduce noise and filter exhaust fumes.
Style K has a push-to-connect fitting that connects to firm tubing, such as nylon, polyurethane, and FEP.

Air-Release Valves for Water and Coolant
These valves are often used to remove air pockets in cooling and heating systems to maintain consistent flow and prevent water surges that can damage equipment. All have a vented relief port to exhaust discharge directly.
Key-Operated Air-Release Valves for Water
- Max. Pressure: 150 psi
- Temperature Range: 33° to 200° F
Turn the key to manually release air from radiators, heaters, and other hot water equipment. These valves have a vented relief port that exhausts discharge directly. Body is nickel-plated brass for good corrosion resistance.
Air-Release Valves for Steam
Our only air-release valves for steam, these seal shut when steam enters the valve to prevent system contents from escaping through the relief port. They are commonly used to eliminate air pockets in steam mains and risers. All exhaust discharge directly through the vented relief port.
