GORE Protective Vents are designed to protect in the
®
harshest environments while quickly and effectively
equalizing the pressure in sealed enclosures. To
maximize the performance of the vent for the lifetime
of your product, please follow the handling and
installation recommendations provided.
Installation Recommendations
1. Preparation
Make sure mounting surface is clean and free of oils, particles
and other contaminants. Isopropyl alcohol can be used to clean
the mounting surface if needed. Ensure the surface is dry prior
to installation.
2. Positioning
For best performance, vents should be mounted on a flat, vertical
surface where liquids or other contaminants will not pool. (See
diagram below for mounting recommendation). Gore molded parts
are designed for mounting to the exterior housing wall.

The Gore proprietary membrane is constructed of ePTFE and allows for the free
passage of gases and vapors while at the same time preventing liquid and
particulates from entering the housing.
To prevent unintentional damage, an additional means of protection
is recommended at the installation site. An example of one possible
means of protection, a protective ring, is shown below:

Handling Guidelines
• Avoid direct contact with GORE
• Do not remove vent cap.
• Do not over-tighten.
• It is recommended to use the following torque wrench sizes
for installation:
Plastic molded parts 16 mm socket or wrench
Metal vent 18 mm wrench
Recommended force 0.6 – 0.8 Nm (0.44 – 0.59 lbf-ft)
3. Installation
To insert into the housing, make sure that the threads have proper
engagement and screw into the housing. If using a socket to tighten
vent to surface, ensure socket is fully engaged with the vent housing
before tightening.
4. Final Inspection
Look over the part to ensure that the vent is properly seated.
