An oral tube is an essential component of every inflatable life jacket, providing a reliable backup inflation method when automatic or manual inflation systems are unavailable. Designed for durability, flexibility, and airtight performance, a high-quality oral inflation tube ensures that users can manually inflate or adjust the buoyancy of their life jackets whenever necessary.

At FAIRDALE, we specialize in manufacturing premium TPU oral tubes for marine safety equipment manufacturers, distributors, and OEM brands worldwide. Made from high-grade thermoplastic polyurethane (TPU), our oral tubes offer excellent flexibility, superior sealing performance, and outstanding resistance to saltwater, UV exposure, and aging.

Whether you are sourcing components for inflatable life jackets, life vests, swim buoys, or other flotation devices, our OEM solutions provide consistent quality, customizable specifications, and reliable global supply.

What Is an Oral Tube?

The oral tube is a flexible inflation tube installed on inflatable life jackets and other inflatable flotation products. It allows users to manually inflate the air chamber by blowing into the tube whenever additional buoyancy is required or when the CO₂ inflation system has been activated but further adjustment is needed.

Unlike automatic inflation mechanisms, an oral inflation tube requires no gas cartridge or mechanical trigger, making it an indispensable emergency backup system. Because of its simple structure and dependable performance, it has become a standard component in marine safety products around the world.

An oral inflation tube consists of a soft TPU tube connected to a one-way inflation valve. During manual inflation, air passes through the valve into the buoyancy chamber while preventing air from escaping.

Its primary functions include:

• Manual inflation during emergencies

• Fine adjustment of buoyancy after CO₂ inflation

• Controlled deflation for storage and maintenance

• Backup inflation if the gas cylinder is unavailable

Compared with traditional PVC tubes, modern TPU oral tubes provide greater flexibility, better durability, and improved resistance to environmental conditions.

How an Oral Tube Works

The operation of an oral tube is straightforward yet highly reliable.

When a user blows into the mouthpiece, air travels through the tube and passes a one-way valve into the inflatable bladder. The valve automatically seals after each breath, preventing air leakage and maintaining buoyancy.

During deflation, the valve can be manually opened to release air gradually, allowing the life jacket to be folded and stored efficiently.

This simple mechanism minimizes maintenance requirements while ensuring dependable operation throughout the product's service life.

Why Every Inflatable Life Jacket Needs an Oral Tube

Although inflatable life jackets are commonly equipped with automatic or manual CO₂ inflation systems, an oral tube provides an additional layer of safety that cannot be overlooked.

There are situations where manual inflation becomes especially valuable:

• After replacing a CO₂ cartridge

• During routine inspection and maintenance

• For buoyancy adjustment after inflation

• When testing the life jacket before use

• In rare cases where the inflation mechanism cannot be activated

For manufacturers, including a high-quality oral inflation tube helps ensure compliance with marine safety standards while improving overall product reliability.

Features of Our TPU Oral Tube

Choosing the right oral tube is essential for maintaining the long-term performance of inflatable life jackets. FAIRDALE manufactures TPU oral tubes using carefully selected materials and precision production processes to ensure consistent quality across every batch.

Our products are designed to meet the demanding requirements of marine safety equipment manufacturers and OEM customers worldwide.

Soft and Flexible TPU Material

Our TPU oral tubes are manufactured from premium thermoplastic polyurethane, a material widely recognized for its excellent balance of flexibility and strength.

Applications of the Oral Tube

The oral tube is widely used across marine safety and flotation product industries. Its simplicity, reliability, and low maintenance requirements make it an essential component in multiple inflatable systems.

Inflatable Life Jackets

The primary application of an oral inflation tube is in inflatable life jackets.

It provides:

• Manual inflation backup in emergencies

• Pressure adjustment after CO₂ activation

• Pre-use buoyancy testing

• Post-use deflation for storage

Every certified life jacket design integrates an oral tube as part of its safety redundancy system. This additional inflation method helps ensure the life jacket remains functional even if the automatic inflation mechanism cannot be used.

Swim Buoys

In open water swimming equipment, oral tubes are used to ensure controlled inflation and deflation of swim buoys.

Benefits include:

• Easy manual inflation before swimming

• Quick adjustment of buoyancy level

• Reliable air retention during long-distance swimming

• Compact storage after deflation

For triathlon and training applications, the oral tube plays a key role in maintaining consistent buoyancy performance. Its user-friendly operation allows swimmers to prepare and pack their equipment quickly and efficiently.

Marine Safety Equipment

Beyond life jackets, oral tubes are also widely used in other marine safety products, including:

• Rescue flotation devices

• Emergency buoyancy bags

• Inflatable safety cushions

• Offshore working safety gear

Their simple structure ensures dependable performance in critical safety situations. This reliability is especially important for offshore operations where flotation equipment must function effectively under demanding environmental conditions.
