Sockolet vs Threadolet – What’s the Difference

Sockolet vs Threadolet

When it comes to selecting pipe fittings for your piping system, you have several options to choose from. Sockolet and threaded fittings are the most commonly used option for connecting pipes. While both fittings look alike, they differ greatly in usage, installation, and overall performance. This blog post will delve into the differences between socket vs threaded fittings and help you decide which one best suits your piping needs.

What is Sockolet Fittings?

A socket fitting is a type of pipe fitting that resembles a small sock or boot. It is an excellent option for connecting small-diameter pipes to larger ones. Sockolet fittings are usually manufactured using forged steel or stainless steel materials. They offer excellent dimensional accuracy and are known for their corrosion resistance, making them a reliable option for harsh industrial environments. Sockolet fittings are designed to be welded onto the pipe, ensuring a tight seal. They are commonly used in applications where there is a need for high-pressure and temperature ratings.

What is Threadolet Fittings?

Threadolet fittings are a type of welded branch connection fitting used to connect pipes with different diameters. They feature a threaded outlet installed between two pipes, forming a strong and durable connection. Threadolet fittings are manufactured using nickel alloys, stainless steel, and carbon steel, making them ideal for high-pressure and high-temperature applications. These fittings suit different liquids, gases, and chemicals thanks to their corrosion resistance properties.

Difference Between Sockolet and Threadolet Fittings

While socket and threaded fittings can connect pipes, they differ in several key factors. Sockolet fittings are usually easier to install than threaded fittings, as they do not require threading onto the pipe like threaded fittings. They are also more cost-effective than threaded fittings, as they are simpler to manufacture. However, threaded fittings are known to offer better mechanical strength than socket fittings, making them a better option for systems that experience high levels of stress. Additionally, threaded fittings can withstand higher pressure and temperature ratings than socket fittings.

Factors to Consider when Choosing a Fitting Option

Some factors must be considered when choosing between the socket and threaded fittings. These include your system’s pressure and temperature rating requirements, the type of media being transported, the pipes’ size, and your budget. If you are on a tight budget or have less-demanding application requirements, socket fittings may be the better option. However, if you require higher durability, strength, and temperature ratings, you should choose threaded fittings.


In summary, the choice between socket vs threaded fittings comes down to your specific application requirements, budget, and personal preference. Sockolet fittings offer affordability, ease of installation, and corrosion resistance. Threadolet fittings, on the other hand, offer better mechanical strength and durability and can handle higher temperatures and pressure ratings. Whether you choose socket or threaded fittings, purchase them from a reputable supplier to ensure they meet the highest quality standards and offer optimal performance.
