Plumbing fittings are crucial components in any piping system, as they ensure the secure connection and proper flow of water and other fluids within residential, commercial, and industrial environments. Among the various types of fittings available, Compression Fittings and SharkBite Fittings stand out due to their unique features and applications. This comparison guide aims to provide an in-depth analysis of these two popular fitting types, examining their mechanisms, advantages, disadvantages, and practical applications, helping you make an informed decision based on your specific needs and circumstances.
Compression fittings are a type of connector used in plumbing and electrical conduit systems to join two pipes or a pipe to a fixture or valve. They create a secure, leak-proof connection by compressing a metal ring, known as a ferrule, onto the pipe using a compression nut. This compression creates a tight seal without the need for soldering, making compression fittings a popular choice for various applications.
Compression Nut: This is the outer part of the fitting that threads onto the body and applies pressure to the compression ring. It is typically made of brass or other durable materials to withstand the pressure and ensure a long-lasting seal.
Compression Ring (Ferrule): The ring or ferrule is the critical component that gets compressed between the nut and the pipe to form a seal. It can be made from various materials, such as brass, copper, or plastic, depending on the application and the type of pipe being used.
Body: The body of the compression fitting houses the pipe and the compression ring. It has a threaded end that connects to the compression nut and a smooth or threaded end that connects to the pipe or fixture.
Compression fittings work by compressing the ferrule between the pipe and the fitting body using the compression nut. Here’s a step-by-step look at how the seal is created:
Insertion: The pipe is inserted into the fitting body, and the compression ring is placed over the pipe.
Threading: The compression nut is threaded onto the fitting body, which begins to compress the ferrule around the pipe.
Compression: As the nut is tightened, it forces the ferrule to deform slightly and grip the pipe tightly, creating a secure seal between the pipe and the fitting.
Sealing: The deformation of the ferrule ensures that the pipe is sealed against the fitting body, preventing leaks. This sealing method is reliable and can be easily disassembled for maintenance or repair.
SharkBite push-to-connect fittings are innovative plumbing connectors that allow for quick and easy installation of pipes without the need for tools, soldering, or adhesives. They are versatile and can be used with a variety of pipe materials, including copper, PEX, CPVC, and PE-RT.
Release Collar: A ring at the end of the fitting that allows the fitting to be easily disconnected when needed. By pushing on the release collar, the grip on the pipe is released, allowing for removal.
Stainless Steel Teeth: Sharp, ring-like teeth inside the fitting that grip the pipe securely when it is inserted. These teeth ensure a strong, reliable hold on the pipe.
O-Ring Seal: A rubber O-ring located inside the fitting that creates a watertight seal around the pipe. The O-ring ensures that no leaks occur once the pipe is inserted.
Fitting Body: The main structure of the fitting that houses the other components. The body is designed to withstand high pressures and provide a secure connection.
SharkBite fittings use a simple push-to-connect mechanism to create a secure seal:
Insertion: The pipe is pushed into the fitting until it reaches the tube stop. No additional tools or steps are required.
Grip: The stainless steel teeth inside the fitting grip the pipe tightly, preventing it from being pulled out.
Seal: The pipe compresses the O-ring inside the fitting, creating a watertight seal. The combination of the grip and the O-ring ensures a leak-free connection.
Straight Couplings: Used to connect two pieces of pipe in a straight line. Ideal for repairs and extending pipe runs.
Elbows: Designed to change the direction of a pipe run by 90 degrees. Commonly used in corners and bends.
Tees: Allow for the creation of a branch line from an existing pipe run. Useful for adding new fixtures or lines.
Caps: Used to cap off the end of a pipe. Perfect for temporary or permanent pipe terminations.
Adapters: Connect pipes to threaded fittings, valves, or fixtures. Available in various configurations for different applications.
Brass: The most common material for SharkBite fittings, brass provides excellent durability, corrosion resistance, and strength. It is suitable for use with all types of pipes SharkBite fittings are compatible with.
Stainless Steel: Used for the teeth and sometimes for the fitting body in certain high-performance or industrial applications. Stainless steel offers superior strength and corrosion resistance.
Tools Required:
Wrenches: Typically, two adjustable wrenches are needed. One wrench holds the fitting body in place, while the other is used to tighten the compression nut.
Pipe Cutter: Used to cut the pipe to the desired length. It ensures a clean, straight cut, which is essential for a proper seal.
Deburring Tool: After cutting the pipe, a deburring tool is used to smooth the cut edges and remove any burrs that might interfere with the seal.
Measuring Tape: For accurately measuring the length of pipe needed.
Marker: To mark the pipe where it needs to be cut.
Measure and Cut: Measure the length of the pipe required and use the pipe cutter to cut it to size. Ensure the cut is straight and clean.
Deburr the Pipe: Use a deburring tool to remove any burrs or rough edges from the cut end of the pipe. This helps in creating a smooth surface for the compression ring to seal against.
Slide on the Compression Nut and Ring: First, slide the compression nut onto the pipe, followed by the compression ring (ferrule).
Insert the Pipe into the Fitting Body: Push the pipe into the fitting body until it stops, ensuring it is fully seated.
Tighten the Compression Nut: Using the wrenches, hold the fitting body in place with one wrench and tighten the compression nut with the other wrench. Tighten the nut until it is snug, but be careful not to over-tighten as this can damage the fitting or the pipe.
Check the Connection: Once tightened, check the connection for leaks. If any leaks are found, tighten the nut slightly more.
