GORE® Protective Vents — Snap-In Series
GORE® Protective Vents Snap-In Series are ePTFE membrane PolyVent components providing pressure equalization, condensation reduction, and ingress protection for sealed outdoor electronic enclosures. The series spans four variants: PolyVent Hysi (PMF100271, 350 ml/min, oleophobic, silicone/TPE body, inside-mount optimized), PolyVent XS (PMF200125, 450 ml/min, oleophobic, PBT-I-GF30), PolyVent Standard (PMF200128, 450 ml/min, oleophobic, PBT-I-GF30), and PolyVent High Airflow in hydrophobic (PMF200484, 2,500 ml/min) and oleophobic (PMF200521, 2,000 ml/min) versions, both PBT-I-GF30. All variants are manufactured with 100% in-line quality inspections; PolyVent XS, Standard, and High Airflow include individual laser-marked traceability. PolyVent Hysi does not include traceability.
IP protection spans IP65 through IP68 (extended immersion: 2 meters for 1 hour) and IP69K depending on housing geometry — not applicable to PolyVent Hysi. All variants are designed for snap-in installation and can be integrated via automated, semi-automated, or manual production lines. Store in cool dry conditions (20–25 °C / 30–50% RH), out of direct sunlight, in original packaging. Manufactured under ISO 9001 quality management system. RoHS compliant — no restricted substances per RoHS Directive 2011/65/EU intentionally added.

GORE® Protective Vents Snap-In Series address the pressure equalization and ingress protection requirements of sealed outdoor electronic enclosures exposed to harsh environmental conditions including rainstorms, dust, salts, and corrosive gases. Pressure changes caused by temperature and humidity cycling stress enclosure seals over time, ultimately leading to failures that allow contaminants to enter and damage internal electronics.
The snap-in PolyVent format provides secure, permanent installation — the snap-in construction seats and seals the vent to the housing reliably — and supports automated, semi-automated, and manual installation on any production line.
The four variants address different enclosure volumes, airflow requirements, and installation preferences. PolyVent Hysi (PMF100271) uses a unique silicone outer hull and TPE carrier ring construction, allows inside-mounting for a nearly invisible exterior profile (0.0 mm installed height from outside when inside-mounted), and suits enclosures up to 3.5 liters; it is the only variant without laser-marked traceability.
PolyVent XS (PMF200125) is 30% smaller than PolyVent Standard — 12.5 mm outer diameter versus 17 mm — and is suited to lightweight, thin-walled enclosures up to 5 liters, with the highest temperature ceiling in the series (+140 °C). PolyVent Standard (PMF200128) provides reliable performance for enclosures up to 5 liters. PolyVent High Airflow is available in a hydrophobic version (PMF200484, 2,500 ml/min) and an oleophobic version (PMF200521, 2,000 ml/min) for enclosures up to 30 liters requiring higher-speed pressure equalization.
PolyVent XS, Standard, and High Airflow are designed for outside installation; PolyVent Hysi is designed for inside installation (outside mounting is also possible but inside is recommended). All variants should be installed on a flat, vertical housing surface where water or other contaminants will not pool.
Environmental performance has been verified by independent laboratories for ingress protection (IEC 60529: IP65, IP66, IP67, IP68 at 2 m for 1 hr; ISO 20653 IP69K — not applicable to PolyVent Hysi), humidity (IEC 60068-2-78: 85 °C, 85% RH, 1,000 hours), salt fog (IEC 60068-2-11 and IEC 60068-2-52), corrosive gas (GR-3108-CORE), temperature (IEC 60068-2-1/2/14: -40 °C to +125 °C; XS to +140 °C; Hysi to +85 °C), vibration (ETSI EN 300 019-2-2 and IEC 60068-2-64 — not applicable to PolyVent Hysi), flammability (UL 94-HB, all PolyVent cap and body materials — not applicable to PolyVent Hysi), and UV resistance (ASTM G155-05a, 1,000 hours).

How do I select among PolyVent Hysi, XS, Standard, and High Airflow?
Selection is driven by enclosure volume, required airflow, installation orientation, and IP requirements. PolyVent Hysi (350 ml/min) is designed for enclosures up to 3.5 liters and is the only variant optimized for inside-mounting — creating a flush exterior when inside-mounted. PolyVent XS (450 ml/min) is 30% smaller than Standard in outer diameter and suited to lightweight, thin-walled enclosures up to 5 liters, with the highest temperature ceiling (+140 °C) in the series.PolyVent Standard (450 ml/min) covers enclosures up to 5 liters in a standard footprint. PolyVent High Airflow (2,000–2,500 ml/min) is for enclosures up to 30 liters; the hydrophobic version (PMF200484) delivers slightly higher airflow; the oleophobic version (PMF200521) adds oil resistance. Only PolyVent XS, Standard, and High Airflow achieve IP68 and IP69K.
Why does airflow rate matter for snap-in enclosure venting?
Airflow rate determines how quickly the vent can equalize pressure differentials between the enclosure interior and the environment. Higher airflow means faster equalization and lower peak seal stress during thermal or humidity cycling — reducing cumulative fatigue and extending seal life. For large enclosure volumes or rapid temperature swings, higher-airflow variants (High Airflow) significantly reduce the duration of pressure stress events compared to lower-airflow variants.
What are the operating temperature ranges for GORE® Protective Vents Snap-In Series?
PolyVent Hysi: -40 °C to +85 °C. PolyVent XS: -40 °C to +140 °C. PolyVent Standard and High Airflow: -40 °C to +125 °C.
Are GORE® Protective Vents Snap-In Series suitable for regulated environments?
W. L. Gore & Associates declares that no restricted substances listed in RoHS Directive 2011/65/EU are intentionally added. All PolyVent cap and body materials (except Hysi) are rated UL 94-HB for flammability. PolyVent XS, Standard, and High Airflow achieve IP65 through IP68 and IP69K per IEC 60529 and ISO 20653.Environmental performance is verified by independent laboratories per IEC 60068-2-78 (humidity), IEC 60068-2-11/52 (salt fog), GR-3108-CORE (corrosive gas), IEC 60068-2-1/2/14 (temperature), ETSI EN 300 019-2-2 and IEC 60068-2-64 (vibration — not applicable to Hysi), and ASTM G155-05a (UV). Manufactured under ISO 9001.
How should GORE® Protective Vents Snap-In Series be specified?
Specify variant (Hysi, XS, Standard, or High Airflow — and hydrophobic or oleophobic for High Airflow), product number, required IP rating, installation orientation (inside for Hysi; outside for XS, Standard, High Airflow), enclosure volume and housing wall thickness, and operating temperature range. Install on a flat, vertical housing surface where water or contaminants will not pool.
