Shipping Details

SharkBite quick-connect fittings are the fastest way to join multiple materials without the need for additional tools, solder, unions or glue. Compatible with PEX, polyethylene, nylon, or soft copper in any combination. These plastic push-to-connect fittings are easy to use and shorten install time. To install, insert the tube into the fitting and the stainless steel teeth bite down and grip tight, while a specially formulated O-ring compresses to create a perfect seal. Disassembly is just as fast by pushing down on the collar with two fingers and pulling the tubing outward allowing the fittings and valves to be easily changed and reused.

What Customers Are Saying

Customers overwhelmingly praise these push-to-connect fittings for their simplicity and reliability. Most highlight effortless installation requiring no special tools or plumbing expertise, with many noting the intuitive push-in design creates secure, leak-free connections quickly. Reviewers consistently report zero leaks across refrigerator ice makers, reverse osmosis systems, and repairs. A key strength is compatibility with mismatched water line sizes, particularly 3/8 to 1/4 inch transitions, eliminating costly re-plumbing. A few users experienced isolated issues or noted the importance of clean tubing insertion. Overall, customers strongly recommend these fittings for reliable, hassle-free plumbing solutions.
