Slip Coupling vs Coupling – What’s the Difference

Slip Couplings vs Couplings

Slip couplings and couplings are two of the most commonly used plumbing fixtures. While they may look similar, they serve different purposes and have many other applications. To help you decide which is suitable for your project, let’s take a closer look at the differences between slips and couplings.

What is Slip Coupling?

Slip couplings are used to connect two pieces of rigid pipe together. They feature several components, including a body that houses two pipe sections with gaskets between them to create a sealed connection. The gaskets are secured in place by tightening the bolts on either side of the coupling using a wrench. This type of coupling is ideal when you need to make minor adjustments or repairs to existing piping without replacing the entire section.

What is Coupling?

Couplings are designed to join two separate lengths of pipe together so that water can flow through it freely without any leaks. Most often, these types of fittings are used in underground installations where pipes penetrate concrete walls or floors. Unlike slip couplings, these fittings do not require gaskets or bolts; instead, they rely on compression fittings that form a tight seal when tightened with a wrench. It’s important to note that while this type of fitting can be used in above-ground applications, its use should be limited due to its lack of flexibility and adjustability compared to other types of fittings, such as slip couplings or flanged joints.

Difference Between Slip Coupling and Coupling

  • A slip coupling, also known as a repair coupling, is a type of pipe fitting that is used to connect two pieces of pipe.
  • A coupling is a device used to connect two shafts together.
  • Slip couplings are typically used when it is necessary to repair or replace a section of pipe.
  • Couplings are used in various applications, including automotive, power transmission, and plumbing.
  • Slip couplings are available in various sizes and materials, including brass, bronze, and plastic.
  • Couplings are available in a variety of styles, including flanged, threaded, and quick-connect.

Conclusion:

In summary, slip couplings and couplings can be valuable tools in your plumbing projects—it just depends on the application you need. Slip couplings provide an easy way to make minor repairs or adjustments without replacing an entire section of pipe, while couplings provide an effective way to join two separate lengths of pipe together in underground applications. So next time you’re wondering which fitting is suitable for your project, consider the difference between slip couplings and couplings before making your decision!
