When it comes to plumbing repairs and installations, choosing the right type of connector can save you time, money, and frustration. Two of the most popular options are compression fittings and SharkBite connectors. But which one should you go for? Both have their advantages and drawbacks, depending on the type of project you’re tackling.
In this blog, we’ll break down the differences between compression fittings and SharkBite connectors, weigh their pros and cons, and help you make an informed decision. Whether you’re a DIY enthusiast or a professional plumber, this guide has got you covered.
What Are Compression Fittings?
Compression fittings are a type of plumbing connector used to join pipes or tubes. They typically consist of three main components:
- A compression nut
- A ferrule (a small ring that compresses against the pipe)
- The fitting body
These connectors work by compressing the ferrule against the pipe as you tighten the nut, creating a watertight seal. They’re commonly used with copper, plastic, or PVC pipes and require manual tightening with a wrench.
Pros of Compression Fittings:
- Strong and Reliable Seal: When installed properly, they create a durable, leak-proof connection.
- Reusable: You can disassemble and reassemble them without damaging the fitting.
- Cost-Effective: Generally cheaper than SharkBite connectors.
- Versatile: Suitable for a variety of pipe materials, including copper and plastic.
Cons of Compression Fittings:
- Requires Tools: Installation needs wrenches and proper tightening.
- More Skill-Intensive: If over-tightened or improperly installed, leaks may occur.
- Time-Consuming: Takes longer to install compared to SharkBite fittings.
What Are SharkBite Fittings?
SharkBite fittings are push-to-connect plumbing connectors that allow you to join pipes quickly and easily without tools. They use an O-ring and stainless-steel teeth to grip the pipe securely, creating a watertight seal. SharkBite fittings work with copper, PEX, CPVC, and HDPE pipes, making them highly versatile for quick repairs or installations.
Pros of SharkBite Fittings:
- Tool-Free Installation: No wrenches, soldering, or glue required—just push the pipe into place.
- Time-Saving: Perfect for quick repairs or emergencies.
- User-Friendly: Ideal for DIYers with minimal plumbing experience.
- Reusable: Can be removed and reused with a special disconnect tool.
Cons of SharkBite Fittings:
- More Expensive: Cost significantly more than compression fittings.
- Not Always Permanent: Though reliable, some plumbers argue SharkBite fittings are better for temporary repairs.
- Compatibility Issues: Works best with smooth, clean pipes; any dirt or damage may cause leaks.
Key Differences Between Compression Fittings and SharkBite Connectors
To make the decision easier, here’s a side-by-side comparison:
| Feature | Compression Fittings | SharkBite Fittings |
|---|---|---|
| Installation | Requires tools like wrenches | Tool-free, push-to-connect |
| Skill Level | Requires moderate plumbing experience | Beginner-friendly, great for DIYers |
| Cost | More affordable | More expensive |
| Durability | Long-term, permanent connection | Reliable, but better for temporary use |
| Reusability | Yes, can be disassembled | Yes, but requires a removal tool |
| Pipe Compatibility | Works with copper, plastic, PVC | Works with copper, PEX, CPVC, HDPE |
When to Use Compression Fittings
Compression fittings are the way to go if:
- You need a permanent, strong connection.
- The pipes you’re working with are static and won’t move.
- You’re comfortable using wrenches and tools.
- Budget is a concern since compression fittings are cheaper.
Where Compression Fittings Work Best
Compression fittings are a go-to choice for situations that require permanence and durability. They excel in settings where pipe movement is minimal, and a watertight seal is crucial. Here are specific applications where compression fittings shine:
- Under-Sink Plumbing Connections
- Perfect for securing water supply lines to faucets.
- Ideal for kitchen sinks, bathroom vanities, and similar setups.
- Water Supply Lines
- Commonly used for connecting pipes in toilets, washing machines, and other appliances.
- Creates a strong seal on both copper and plastic pipes.
- Household Plumbing Repairs
- Excellent for long-term repairs where pipes won’t be disassembled.
- Great for connecting copper or PVC pipes in fixed locations.
- Industrial and Commercial Systems
- Used in HVAC systems, refrigeration lines, and high-pressure water systems.
- Provides a reliable seal in complex, high-pressure environments.
- Boiler Systems and Radiators
- Compression fittings are widely used in heating systems, where high temperatures and pressure require a secure connection.
Why Compression Fittings Are Reliable
- Durability: Once tightened, the fitting ensures a leak-proof and lasting connection.
- Reusability: They can be removed and reinstalled without compromising their strength.
- Cost-Effective: Far more budget-friendly than SharkBite connectors.
Where They Aren’t Ideal
Compression fittings aren’t always suitable in scenarios with:
- Frequent pipe movement or vibrations
- Tight spaces where using wrenches is impractical
- Immediate or temporary repairs
When to Use SharkBite Fittings
SharkBite fittings shine in situations where speed and ease are priorities:
- You’re making a quick repair or working on a temporary fix.
- You don’t have access to tools or are in a tight space.
- You’re a beginner or want a DIY-friendly solution.
- You’re working with PEX, CPVC, or mixed pipe materials.
SharkBite Fittings: Applications and Benefits
Where SharkBite Fittings Excel

Which Option Is Right for You?
Deciding between compression fittings and SharkBite connectors boils down to your needs, skill level, and budget.
- If you’re a professional plumber or need a long-term, reliable connection, compression fittings are the better choice. They’re durable, cost-effective, and proven for permanent installations.
- If you’re a homeowner or DIYer looking for a quick, hassle-free solution, SharkBite fittings will save you time and effort.
Pro Tip: Keep both on hand! SharkBite fittings are great for emergencies, while compression fittings ensure long-term reliability.
