Hi, Thank you for contacting SharkBite. The SharkBite 3/4 in. Push-to-Connect Brass Coupling Fitting can be buried but it must be wrapped with a silicone wrap to protect the fitting from coming in contact with the soil. I've attached a link to the installation manual which covers burial on page 6. I've also attached a link to the silicone wrap. If you have any more questions or if we can be of any further assistance you can call tech support at 877-700-4242.
