M32 Plastic Valve Screw Vent

Integrated structure for pressure equalization and environmental protection

Design Overview

The M32 Plastic Valve Screw Vent features an integrated structure designed for pressure equalization and environmental protection. Its core components work in tandem to balance air pressure while blocking liquid and dust ingress.

Main Body Structure

The main body is crafted from durable plastic, shaped with a hexagonal top for easy tool-assisted installation and removal. This body integrates external threading that enables secure screw-in fixation to enclosures, ensuring stable attachment even in vibrating environments.

Membrane Technology

A critical part of the structure is the oleophobic e-PTFE membrane, which is permanently bonded to the inner section of the body via ultrasonic welding or hot pressure techniques. This membrane serves as the functional core, allowing air and vapor to pass through freely while repelling water and oils.

Key Features

Integrated structure for pressure equalization and environmental protection

Durable plastic body with hexagonal top for easy installation

External threading for secure screw-in fixation

Oleophobic e-PTFE membrane bonded via ultrasonic welding or hot pressure

Membrane allows air and vapor passage while repelling water and oils

Silica gel O-ring for enhanced sealing performance

Maintains structural integrity across wide temperature range

Materials selected for chemical resistance and hydrolytic stability

Sealing Performance

To enhance sealing performance, the vent incorporates an O-ring made of silica gel. This ring sits between the vent body and the mounting surface, creating a tight barrier that prevents external contaminants from seeping in around the edges.

Structural Integrity

The entire assembly is engineered to maintain structural integrity across a wide temperature range, with materials selected for chemical resistance and hydrolytic stability.

Layered Structure

This layered structure—combining the threaded plastic housing, protective membrane, and sealing ring—delivers both reliable venting functionality and robust environmental protection.

Applications

This product is suitable for outdoor electronic enclosures and harsh industrial settings where reliable pressure equalization and environmental protection are required.
