Do I Need to Use Sleeve Insert for Compression Sleeves?

Compression sleeves are widely used by athletes, individuals with medical conditions, and those seeking enhanced performance and recovery. These flexible, stretchable garments are designed to provide support, improve blood circulation, and reduce muscle soreness and fatigue. While compression sleeves offer numerous benefits, whether or not to use sleeve inserts with them is a topic often debated. Sleeve inserts, usually made of gel or silicone, are intended to enhance the effectiveness of compression sleeves by targeting specific areas, providing additional support, and reducing localized swelling.

Do Compression Fittings Need Inserts?

The use of an insert is crucial for the proper functioning and longevity of compression fittings. When installing Speedfit pipes, it’s essential to include an insert as it provides support to the shape of the pipe. The insert ensures that the pipe doesn’t collapse or deform under pressure, maintaining the integrity of the fittings.

There are two types of inserts available for different types of connections. The STS or Superseal insert is designed for plastic to plastic connections. This insert is specifically engineered to create a tight seal and prevent leakage, ensuring a reliable and watertight connection.

On the other hand, the TSM insert is suitable for plastic to compression connections. It helps to maintain the shape of the plastic pipe and prevents any potential collapse or deformation, ensuring a secure and durable connection.

Always use inserts when installing compression fittings, regardless of the type of connection you’re making.

Types of Compression Fittings and Their Applications

Compression fittings are commonly used in plumbing and gas utilization systems to join pipes or tubes together. They come in various types, such as compression sleeve fittings, compression elbow fittings, and compression tee fittings.

Compression sleeve fittings are used for connecting and sealing copper or plastic pipes. They consist of a compression nut, compression sleeve, and fitting body. These fittings are primarily used in residential and commercial plumbing installations.

Compression elbow fittings are designed to connect pipes at a 90-degree angle. They’re commonly used in areas where pipes need to be bent or redirected. These fittings are widely utilized in plumbing systems to achieve secure and leak-free connections.

Compression tee fittings are used to branch off a main pipeline into multiple directions. They typically consist of a T-shaped fitting body with compression nuts and sleeves. Compression tee fittings are widely used in plumbing systems, particularly in applications where multiple connections are required.

These compression fittings are favored in various applications due to their ease of installation, reusability, and reliable leak-free connections. They offer a convenient and efficient method for joining pipes or tubes together without the need for heat or solder.


While some individuals may find that using a sleeve insert enhances their overall experience by providing added comfort, support, or customization, others may not feel the need for this additional layer. Factors such as the intended use of the compression sleeve, personal comfort level, and desired level of compression should be taken into consideration when making this decision.
