Permanently Integrated ePTFE Venting
Weld Venting Directly Into Your Enclosure — No Separate Hardware Required
Gore weldable ePTFE vent membranes bond ultrasonically or thermally to your plastic enclosure housing, creating a seamless, permanently integrated vent with no gaskets, adhesives, or mechanical fasteners to age or loosen over time.

Ultrasonic or heat-weldable ePTFE vent membranes for seamless integration into plastic enclosures without additional hardware. Weldable vents eliminate the separate vent body entirely — the ePTFE membrane is welded directly onto a prepared surface or into a port in the enclosure shell during manufacture, creating a monolithic assembly with no secondary sealing interfaces. Available in custom shapes and sizes to match enclosure aperture geometry, these vents are ideal for high-volume consumer electronics, outdoor luminaires, and telecom equipment where component count reduction and sealing reliability are paramount.
Why Choose Gore Weldable Outdoor Electronics Vents?
Monolithic Seal — No Interface to Fail
By welding the ePTFE membrane directly to the enclosure material, the vent-to-housing joint is eliminated as a failure mode. There is no adhesive bond that degrades in UV exposure, no O-ring that compresses and creeps, and no threaded joint that loosens under vibration. The resulting assembly passes IP67/IP68 testing with the same reliability as the base enclosure seal.
Custom Shapes for Any Aperture
Gore weldable membranes are die-cut to virtually any shape — round, rectangular, slot, or complex contour — matching the aperture geometry defined in your enclosure tooling. This eliminates the constraint of round standard vent diameters and allows vent area to be optimized for airflow requirements without modifying the part's structural cross-section.
Clean Manufacturing Process
Ultrasonic welding is a fast, clean, and repeatable bonding process compatible with standard enclosure assembly lines. No adhesive dispensing, cure time, or contamination risk. Heat welding (laser or hot-plate) is equally clean and automatable. Both processes integrate directly into existing plastic welding stations with no additional consumables.

Frequently Asked Questions
Which enclosure plastics are compatible with ultrasonic welding of Gore ePTFE membranes?
Gore weldable membranes are compatible with a wide range of engineering thermoplastics including ABS, PC, PC/ABS blends, PA (nylon), PBT, and PP. The enclosure design must include a weld land (flat annular surface around the aperture) of sufficient width for the weld sonotrode geometry. Gore provides weld parameter recommendations for each material combination.
Can weldable vents be applied retroactively to existing enclosure tooling?
Retroactive application requires that the existing enclosure has a suitable flat weld land around a vent aperture. If the aperture does not exist, tooling modification is needed. Weldable vents are most cost-effective for new designs where the aperture and weld land are specified in the original tooling. Contact RSTECH for feasibility assessment of existing enclosures.
What IP rating can be achieved with weldable vents?
When correctly welded using qualified parameters, Gore weldable vents achieve IP67 and IP68 protection levels. The actual rating depends on the enclosure overall design, additional seal interfaces, and testing protocol. Gore provides application engineering support for IP validation.
Are custom membrane shapes available through RSTECH Electronics?
Yes. RSTECH works with Gore to supply custom die-cut membrane shapes and sizes. Tooling for custom shapes is typically amortized into volume orders. Contact us with your aperture drawing and volume forecast to discuss a custom supply program.
