Less than a quarter of the height of standard pressure-relief valves, these are often installed on tanks in low-clearance areas.

Body is brass or nickel-plated brass. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

For corrosion resistance in wet conditions and harsh environments, these valves have a 303 stainless steel body. All meet ASME Code Section VIII for use with air and inert gas pressure vessels.

Choose these valves for small steam-heating boilers requiring pressure relief between 5 psi and 12 psi.

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

Body is brass.

An internal wire brush traps air bubbles and discharges them through the top relief port while allowing inline flow from the inlet to the outlet.

Use this valve with oil, diesel fuel, gasoline, and kerosene.

Protect against excess vacuum and pressure in cylinders, gear boxes, enclosures, manifolds, and tanks.

These breather vents withstand corrosion in damp environments.

Shield outdoor pipe and tank openings from the environment. Also known as vent caps, these breather vents have screens to allow air flow while blocking debris.

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

Use these vents to maintain consistent pressure as temperatures fluctuate by allowing air to flow through sealed enclosures.

No threaded hole or tools needed—snap these vents into enclosures with a maximum 1/8” panel thickness to let airflow in and keep water out even when submerged.

These vents maintain air pressure inside enclosures that may be exposed to indoor and outdoor temperature changes while keeping dust and water out.

Mount to the outside of your enclosure to prevent moisture from being trapped inside.

Attach these vents to the top or side of sealed enclosures, so air can flow through to equalize internal and external temperature and pressure.

Safe for use around flammable and combustible gases, vapors, fibers, and dust, these drains let moisture buildup from temperature changes inside enclosures drip out to keep electronics dry.
