Flame Arrestor Vents safeguard against battery explosions.

September 25, 2014

Made of hydrophobic Vyon® materials, Flame Arrestor Vents safeguard from potential explosions in lead acid batteries. Sintered porous plastic materials offer chemical compatibility and are resistant to most acids. Creation of flow path, by which gases released through valve element can escape from battery, prevent propagation of potential flames. In addition to preventing sparks from entering battery, vents provide controlled airflow, minimizing risk of acid spillage. Read More


Hip Roof Vent provides effective attic ventilation, protection.

May 13, 2014

Intended for roof designs with long, sweeping hips and cut-up planes, Cobra® Hip Vent offers 9 in.² of NFA for effective exhaust venting on homes with little or no ridge. Dual Weather Fighter™ Filter, included, helps prevent weather infiltration through and under vent. Low-profile (5/8 in.), shingle-over design minimizes visibility when installed at hip, consequently promoting exterior aesthetics, while fully nail-gunnable nature helps accelerate installation.

Portable Electronic Vents provide waterproof protection.

March 3, 2014

Intended for smartphones and portable electronic devices, PE3 Series provides typical airflow of 3,300 ml/min/cm³, equalizing internal  pressure, minimizing stress on seals, and eliminating transducer bias. At same time, vents protect internal electronics by serving as barrier against liquid, dust, and dirt. Units are engineered with black oleophobic membrane and gray PET nonwoven backing to minimize contrast when mounted on exterior of dark electronic devices. Read More

Breather Vent protects automotive electronic housings.

December 6, 2013

GORE® PolyVent Compact Series features microporous GORE™ membrane that breathes to allow airflow yet blocks entry of water and contaminants. This provides protection for sensitive components, such as sensors, motors, and control units, as well as pressure equalization. Vent diameter is 14.3 mm, and 3.45 mm installed height minimizes external protrusion and vulnerability to mechanical impacts or steam-jets. Construction features hydrostabilized PBT GF30 vent body and silicone O-ring. Read More
