Remote-Located Pressure Equalization for Sealed Enclosures
Vent Where You Need It — Not Where It's Convenient
Gore tube-mount vents decouple the ePTFE membrane from the enclosure wall, routing pressure equalization through a flexible tube to a protected location — solving venting challenges in enclosures where surface mounting is geometrically impossible or thermally impractical.

Tube-mounted vents routing pressure equalization to a remote location, ideal for sealed enclosures where surface mounting is impossible. The ePTFE membrane is housed in a separate body connected via a silicone or PTFE tube to the sealed enclosure. This configuration allows the vent to be placed in a sheltered or accessible location while the enclosure itself remains fully sealed against liquid and particulate ingress. Used in gearboxes, densely packaged electronics housings, and enclosures with complex internal geometry where a wall-mount vent would be obstructed or exposed to direct fluid impingement.
Why Choose Gore Tube-Mount Outdoor Electronics Vents?
Vent Placement Freedom
When enclosure geometry, internal component density, or thermal management layouts prevent conventional wall-mounting, the tube-mount configuration routes the venting function to any accessible location. The flexible tube can be routed around components, through bulkheads, or into a sheltered cavity — giving engineers freedom unavailable with adhesive or screw-in designs.
Protection of the Membrane from Direct Fluid Exposure
In applications where the enclosure surface is subject to direct high-velocity liquid impingement — submerged gearboxes, wash-down equipment, or marine electronics — positioning the vent body remotely via tube prevents membrane saturation and maintains full airflow. The membrane sees only the pressure differential, not the fluid.
Compatible With Gearbox and High-Contamination Environments
Gearboxes and industrial drives generate significant internal pressure swings from thermal cycling and fluid agitation. Tube-mount vents tolerate the oil-mist and particulate environment of the gearbox interior while venting to atmosphere at a remote, clean point — preventing shaft seal failure caused by excess internal pressure.

Frequently Asked Questions
What is the maximum tube length that maintains effective pressure equalization?
Effective tube length depends on tube inner diameter, membrane airflow resistance, and the pressure differential cycle rate of the application. Gore provides application engineering guidance for tube length selection. For most electronics applications, lengths up to 500 mm are practical. Contact RSTECH for application-specific analysis.
Can tube-mount vents handle oil mist from gearbox interiors?
Yes. The ePTFE membrane is chemically inert and hydrophobic, resisting oil wetting. Oil mist contacting the membrane from the gearbox side does not block airflow — the membrane surface tension prevents liquid oil from passing through while allowing air pressure equalization. This is a primary application for tube-mount vents.
How is the tube connected to the enclosure?
The tube connects via a barbed or compression fitting integrated into the enclosure wall. Gore and RSTECH can provide guidance on fitting selection and enclosure modification requirements. For new designs, tube routing and fitting specifications should be determined during early enclosure design.
