Add a filling port to your hydraulic tank while protecting against excess pressure and vacuum. Breather vents stop debris from entering your tank. Mount them on top of standard tank openings with included hardware.

Keep moisture, dirt, and debris from entering your oil reservoirs. The silica gel inside these breather vents absorbs moisture from the air, preventing rust from forming inside your tanks. The gel changes from blue to pink as it becomes saturated, letting you know it needs to be replaced. A second filter blocks dust and other particles from getting inside. These breather vents allow air to flow in and out of your lubrication system, keeping excess vacuum or pressure from building up in cylinders, gear boxes, and tanks.

For an extended service life, use breather vents with a steel body. They are stronger than breather vents with plastic bodies and hold up better when exposed to chemicals. A window lets you check the color of the gel. No need to replace the entire unit when the gel is saturated—use rebuild kits to add fresh gel and to replace the window, filters, and gaskets.

A small hex size makes these high-flow mufflers a good fit for cramped spaces. Commonly used with high-flow, air-powered equipment, such as diaphragm pumps and valves, they reduce noise and filter exhaust fumes without restricting flow.

Replace your muffler less often—these have a filter design that stays clean longer than porous mufflers. They’re often used in air-powered circuits to reduce noise and filter exhaust fumes.

Style A has a screw on top to adjust air flow.

These mufflers exhaust through narrow holes on one end to provide a concentrated blast of air. Use them to eject items from your conveyor and direct exhaust away from delicate applications. They have an external hex drive so they can be tightened with a wrench.

Also known as reclassifiers, these mufflers have a clear reservoir with a drain plug to remove and store oil mist for reuse. Mufflers must be mounted vertically.

Install these mufflers in air-powered drills and other loud equipment. They filter exhaust fumes and reduce noise by 30-35 dB, a reduction that's equivalent to putting in earplugs.

Mufflers with pipe connections thread into NPT or metric threaded exhaust ports.
