To prevent the ingress of oily liquids, water, dust, dirt, salts, or other contaminants into your electronics, OxySeal® pressure compensation units can be deployed as an easy plug-and-play venting solution for housings having inverted cylindrical openings. Using hydrophobic track-etched membranes, these injection molded plugs – which can also be treated to be oleophobic – are composed with a thermoplastic elastomer seal that does not require an additional anchor or fastener to ensure a tight fit.
Beyond its standard portfolio, OxySeal® can also be fully customizable. This includes selection of the dimensions, shape, and membrane properties specific to your application’s requirements.

Delivering Precision & Control: An Introduction to Track-Etched Membrane Technology
Ideally suited for in-house and large-scale manufacturing applications, Oxyphen’s track-etched rollstock membrane can be laminated, unlaminated, or fiber-based – supplied from polyester (PET) or polycarbonate (PC) high quality raw materials.
OxyPad® Self-Adhesive Pads
OxyPad® membrane pads, which are easily integrated inside or outside your housing design, promote consistent pressure equalization and protection against water, dust, and other harmful particulates.
OxyDisc® Die-Cut Membrane Discs
OxyDisc® die-cut membrane discs can be easily mounted and produced using either hydrophobic or hydrophilic membranes for a variety of filtration or venting application requirements.
Membrane Technologies Available
Unique-Mem® Unlaminated Track-Etched Membranes
Unique-Mem® unlaminated track-etched membranes, available as hydrophilic or hydrophobic, are characterized by cylindrical shaped pores penetrating the membrane in different angles. They have a smooth flat surface and well-defined flow rates.
RoTrac® Laminated Track-Etched Membranes
RoTrac® laminated track-etched membranes are Unique-Mem® membranes that are supported with non-wovens (PP or PET) to create a more robust membrane. They are available as either hydrophilic or hydrophobic membranes.
Fiber-based membranes are surface modified using a super-hydrophobic coating to repel water and other liquids while still allowing maximum airflow.
