This blog post will delve into the key differences between compression fittings and SharkBite fittings, two popular methods for connecting pipes. Compression fittings utilize a mechanical seal created by a nut, ferrule, and fitting body, offering a reliable solution for connecting rigid pipes like copper or steel.
SharkBite fittings, on the other hand, employ a unique push-to-connect mechanism. Simply insert the pipe into the fitting, and the internal components create a secure seal. This innovative design eliminates the need for soldering, crimping, or any special tools, making installation incredibly fast and easy.
What Are Compression Fittings
Compression fittings are a type of mechanical coupling used to connect pipes or tubes. They rely on a compression mechanism to create a secure seal, eliminating the need for soldering or other joining methods.
These fittings typically consist of three main parts: the fitting body, a compression nut, and a ferrule (also known as an olive). The ferrule is a small ring that is compressed between the fitting body and the nut when the nut is tightened. This compression creates a tight seal around the pipe, preventing leaks.
Compression fittings offer several advantages, including ease of installation, reusability, and suitability for a wide range of materials, including copper, plastic, and stainless steel. They are commonly used in plumbing, refrigeration, and other applications where a reliable and easily assembled connection is required.
What Are Sharkbite Fittings
SharkBite fittings are a type of push-to-connect fitting that revolutionized plumbing installation. They utilize a unique system of stainless steel teeth that grip the pipe when inserted into the fitting. Simultaneously, an O-ring compresses to create a secure and leak-proof seal.
This innovative design eliminates the need for traditional methods like soldering or gluing, making installations significantly faster and easier. SharkBite fittings are compatible with a variety of materials, including copper, PEX, CPVC, and PE-RT, offering versatility for various plumbing projects.
The ease of installation and reliable performance of SharkBite fittings have made them a popular choice for both professional plumbers and DIY enthusiasts.
