These valves are made of corrosion-resistant materials for use in wet conditions and harsh environments.

For excellent corrosion resistance in wet conditions and harsh environments, these valves have no metal parts.

Turn the key to manually vent radiators and heaters.

Eliminate air pockets in your drinking water system with these valves. They meet NSF/ANSI 61, which designates them as safe to use with drinking water.

Place these diffusers in the grid of a drop ceiling to distribute air evenly throughout your space.

No additional fittings or collars needed.

Connect diffusers to duct.

Evenly disperse airflow into a room to maintain a consistent temperature throughout the space.

Cover the opening where air is pulled into your HVAC system.

Place these grilles in the grid of a drop ceiling.

Install onto floor ducts to direct hot and cold air from your HVAC system.

No need for clamps or connectors—duct and fittings have a male end that is slightly smaller than its female end for simple assembly.

Mount these louvers into openings that are too small for most louvers. They are sized for use in block and brick walls.

The included filter cleans the air as it passes through these louvers.

Get an exact fit for your opening by sliding out these louvers to the width you need.

Use these louvers in harsh environments—they won't rust.

Relieve heat and moisture buildup in enclosures and other small spaces.

A spring-loaded fusible link locks the blades closed if the temperature reaches 167° F. Louvers meet UL 10C fire requirements.

Cover chimneys to reduce downdrafts and prevent obstructions from entering.

For use with gas-fired equipment, such as boilers and furnaces, these vent pipes and fittings withstand temperatures up to 400° F. Also known as type B gas vents.

These breather vents withstand corrosion in damp environments.

Minimize moisture buildup in enclosures. Also known as drain plugs, these breather vents have a small outlet that allows condensation to drain.

Add a filling port to your hydraulic tank while protecting against excess pressure and vacuum.

Keep moisture, dirt, and debris from entering your oil reservoirs.

Adjust flow by turning the screw, then tighten the hex nut with a wrench to secure.

Commonly used with high-flow, air-powered equipment, such as diaphragm pumps and valves, these mufflers reduce noise and filter exhaust fumes without restricting flow.

These mufflers can be cleaned for an extended service life.

Replace your muffler less often—these have a filter design that stays clean longer than porous mufflers.

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

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.

Don’t let an unexpected clog interrupt your work. These mufflers have a filter that slides up slowly as it clogs to indicate when the muffler should be replaced. They reduce noise by 30-35 dB.

For the highest level of protection from water, these vents rated IP68 for protection from water submersion.

These conductive aluminum screens block electromagnetic interference (EMI) and radio frequency interference (RFI) to prevent electrical problems such as radio static and faulty signals. Made of mesh, they let air flow through, so the pressure in your enclosure stays constant as temperatures fluctuate.
