GORE® Protective Vents — Screw-In Series
GORE® Protective Vents Screw-In Series are oleophobic ePTFE membrane PolyVent components providing pressure equalization, condensation reduction, and ingress protection for sealed outdoor electronic enclosures. The series spans seven product variants across a wide range of airflow capacities and enclosure sizes: PolyVent XS (M6×0.75, 300 ml/min), PolyVent Standard in M12×1 and M12×1.5 (450 ml/min), PolyVent High Airflow M12×1.5 (4,000 ml/min), PolyVent High Airflow PRO in M12×1 and M12×1.5 (7,600 ml/min), PolyVent Stainless Steel M12×1.5 (1,600 ml/min), PolyVent Ex+ M12×1.5 (1,600 ml/min, IECEx/ATEX certified), and PolyVent XL M32×1.5 (16 l/min at dp = 12 mbar). All variants use ePTFE membrane with oleophobic treatment and silicone 60 Shore A o-rings, and all cap/body/o-ring materials (non-metal variants) are rated UL 94 V-0. All variants include individual laser-marked traceability except PolyVent XL.
IP protection spans IP65 through IP68 (extended immersion: 2 meters for 1 hour, or up to 72 hours for PolyVent XS) and IP69K (all variants except PolyVent XS) per IEC 60529 and ISO 20653. 100% quality control is applied to all vents with thread size M6 and M12. Manufactured under ISO 9001 and ISO 14001 management systems. RoHS compliant — no restricted substances per RoHS Directive 2011/65/EU intentionally added.

Common industries: Telecommunications, industrial automation, outdoor electronics, utilities, solar energy, hazardous area equipment.
GORE® Protective Vents Screw-In Series are engineered for the mechanical stresses and chemical exposures of harsh outdoor environments including telecommunications infrastructure, industrial control enclosures, utility metering, outdoor lighting, and solar installations. Pressure buildup inside sealed enclosures driven by temperature, altitude, and humidity cycling stresses enclosure seals over time, leading to ingress failures that allow water, salts, corrosive liquids, and particulates to damage internal electronics.
The screw-in PolyVent format provides secure, removable installation — the rugged construction, improved cap design, and o-ring keep the vent reliably secured under vibration, mechanical shock, and aggressive cleaning.
The portfolio is organized by airflow tier and housing requirement. PolyVent XS (M6×0.75, 300 ml/min) addresses the smallest enclosures up to approximately 2 liters with a compact footprint; it achieves IP68 extended immersion up to 72 hours. PolyVent Standard (M12, 450 ml/min) covers enclosures up to approximately 5 liters. PolyVent High Airflow (M12×1.5, 4,000 ml/min) addresses enclosures up to approximately 20 liters.
PolyVent High Airflow PRO (M12, 7,600 ml/min) handles enclosures to approximately 50 liters with both individual laser marking and DMC code traceability. PolyVent Stainless Steel (M12×1.5, 1,600 ml/min) uses stainless steel (1.4404/316L) body and cap with IK10 mechanical impact rating for the most demanding physical environments. PolyVent Ex+ (M12×1.5, 1,600 ml/min) is IECEx and ATEX certified for use in explosive environments (Ex II 2G Ex eb IIC Gb; Ex II 2D Ex tb IIIC Db), using the same stainless steel housing as the Stainless Steel variant.
PolyVent XL (M32×1.5, 16 l/min) addresses the largest enclosures to approximately 200 liters with a polycarbonate housing and O-Ring 55×3.2.
All non-metal cap, body, and o-ring materials are UL 94 V-0 rated. GORE Membranes in PolyVent XS, Stainless Steel, and Ex+ additionally carry UL 94 VTM-0 ratings.
Environmental performance has been verified by independent laboratories per IEC 60529 (ingress), IEC 60068-2-78 (humidity: 85 °C, 85% RH, 1,000 hours), IEC 60068-2-11/52 (salt fog), GR-3108-CORE (corrosive gas), ETSI EN 300 019-2-2 and IEC 60068-2-64 (vibration), IEC 60068-2-1/2/14 (temperature: -40 °C to +125 °C, or +150 °C for PolyVent XS), IEC 62262 IK10 (Stainless Steel only), IEC 62108 10.8/10.9 (PolyVent XL solar testing), and IECEx/ATEX directives (Ex+ only).
RoHS Directive 2011/65/EU — no restricted substances intentionally added. Manufactured under ISO 9001 and ISO 14001.
How do I select the right PolyVent Screw-In variant for my enclosure?
Selection is primarily driven by enclosure volume and required airflow rate, then by environmental requirements. PolyVent XS (300 ml/min) suits enclosures up to ~2 liters; Standard (450 ml/min) to ~5 liters; High Airflow (4,000 ml/min) to ~20 liters; High Airflow PRO (7,600 ml/min) to ~50 liters; PolyVent XL (16 l/min) to ~200 liters. For explosive atmospheres, specify PolyVent Ex+. For IK10 mechanical impact resistance, specify PolyVent Stainless Steel. For solar installations requiring hail and freeze-thaw testing, specify PolyVent XL.
Why is airflow rate critical for sealed enclosure pressure equalization?
The relationship between airflow and seal life is direct: higher airflow → faster pressure equalization → lower duration and magnitude of differential pressure stress on seals → longer seal life. For large enclosure volumes or applications with rapid thermal swings — such as outdoor cabinets in direct sunlight — inadequate airflow allows prolonged pressure differentials that fatigue seals and admit contaminants. Gore's PolyVent Screw-In portfolio chart maps typical airflow to enclosure size to guide selection.
What are the operating temperature ranges for GORE® Protective Vents Screw-In Series?
All variants are tested to -40 °C (low). Maximum operating temperatures are +125 °C for Standard, High Airflow, High Airflow PRO, Stainless Steel, Ex+, and XL variants, and +150 °C for PolyVent XS.
Are GORE® Protective Vents Screw-In Series suitable for hazardous and regulated environments?
Yes. All non-metal cap, body, and o-ring materials are UL 94 V-0 rated. GORE Membranes in PolyVent XS, Stainless Steel, and Ex+ additionally carry UL 94 VTM-0 ratings. PolyVent Ex+ is IECEx and ATEX certified (Ex II 2G Ex eb IIC Gb; Ex II 2D Ex tb IIIC Db) for explosive gas and dust environments. PolyVent Stainless Steel is IK10-rated per IEC 62262. RoHS Directive 2011/65/EU — no restricted substances intentionally added. Manufactured under ISO 9001 and ISO 14001.
How should GORE® Protective Vents Screw-In Series be specified?
Specify variant (XS, Standard, High Airflow, High Airflow PRO, Stainless Steel, Ex+, or XL), thread size and product number, color (black or gray for polyamide variants), required IP rating, counter nut requirement (included for XS, High Airflow M12×1.5, XL; not included for Standard M12×1, High Airflow PRO M12×1, Ex+), installation torque, and through-hole diameter with chamfer. Install on a flat, vertical housing surface with the cap on the exterior of the housing.
