Why it matters: SharkBite fittings are approved by universal standards and include features that go above and beyond the industry standards. The rigorous third-party testing and code requirements of each fitting ensure a secure behind-the-wall connection.

2. In-House Manufacturing

In addition to meeting these industry codes and standards, SharkBite fittings are also made of the highest quality materials and are meticulously inspected in-house to ensure the same reliable product leaves the manufacturing facility every time. Unlike other push-to-connect fitting brands, SharkBite owns its manufacturing process from start to finish. Because of this, SharkBite can closely inspect the raw materials, fix assembly issues faster and use quality tests that go above industry standards.

We also use the best materials for our fittings. SharkBite couplings are made of lead-free, dezincification-resistant brass to protect it from degrading in hard-water conditions. To address concerns about chemicals and fluctuating temperatures, SharkBite uses chlorine/chloramine-resistant EPDM O-rings. Our fittings also use a strong stainless steel 316 grab ring.

The easy-to-use design makes for quick and easy installation and is compatible with PEX, copper, CPVC, PE-RT and SDR-9 HDPE pipe. Take a look inside a push-to-connect fitting below.

Why it matters: Using the right products can make or break your plumbing job, so pick fittings you can trust. SharkBite’s control over its manufacturing reduces both human and automated errors so you get a high-quality product every time.

3. Time Tested

SharkBite fittings have been manufactured and used in Australia since the 1990s, making it a tried and trusted product for over 30 years. In fact, a SharkBite connection is made every 2.5 seconds, and plumbers have used them for underground repairs, new rough-in plumbing installations and remodels.

With SharkBite Max, these features are enhanced. Not only has its pressure rating increased to 400 psi, but its new stainless steel retainer allows it to withstand double the pressure as the first-generation fitting, giving you an even stronger connection.

Why it matters: You can have confidence knowing SharkBite is not just a temporary fix, but a long-term solution that other professionals have taken advantage of for years. With the proper installation, there are no replacements necessary.

A Faster, Safer Solution

Now that you know SharkBite fittings are approved for use behind walls, there are a few reasons why you should use them over other fittings and methods.

Versatility. SharkBite fittings require no special tools, crimping, glue or soldering and connect to multiple pipe types. This makes installations more efficient than other plumbing solutions. For a connection you can trust, look for the shark. SharkBite Max has the shark printed right on the stainless steel retainer so you can be sure you’re not using a fakebite.

Speed. Because SharkBite can be installed in wet lines, your customer’s water supply is available much sooner than if your team used traditional plumbing methods. This is because you can turn the water on and test your lines immediately after installing the plumbing — no need to wait for glue or pipes to dry.

Safety. Saving time is a top priority when going from site to site, but safety should always be paramount. The ease of push-to-connect fittings not only makes installations faster, but it also eliminates safety concerns like using a torch in cramped areas.

Why it matters: Behind-the-wall installations are often in tight spaces with little room for error, so fast and safe installation is imperative. SharkBite fittings don’t require drying time and streamline connections with their easy-to-use design.

Tips for Installing SharkBite Fittings

While codes and standards are designed to ensure that your plumbing products are safe to use in particular applications, they can’t save an improper installation from failing.

To help make sure you’re using SharkBite fittings properly, we’re breaking down some of the most common installation errors we see and how you can avoid them to ensure you’re making proper permanent connections with SharkBite.

Common Causes of Fitting Failure

  • Uneven pipe cut.
  • Fitting not pushed in completely.
  • Incomplete deburr that punctures o-ring.

Avoid Incorrect Installations By

  • Checking for debris on the pipe.
  • Replacing broken pipe.
  • Ensuring you are using the correct fitting for the pipe type and function. Check the collar colors for pipe compatibility. Gray collars connect to polybutylene, white connects to PVC, and tan connects to PEX, copper, CPVC, PE-RT and HDPE SDR-9 pipe.
  • Always mark the insertion depth on your pipe so you know that the fitting is pushed in all the way.
  • First generation fittings are specifically designed to ensure a reliable connection but should not be disconnected and reconnected repeatedly. The only way to properly remove SharkBite fittings is to use the SharkBite disconnect tongs, clip or tool.
