Q: What are SharkBite® fittings?
A: SharkBite fittings are the core products within the SharkBite Connection System, and provide the easiest and most dependable way to join Copper, CPVC or PEX pipe in any combination with no solder, clamps, unions or glue. When you insert the pipe, the stainless steel teeth on our quick-connect fittings bite down and grip tight, while the specially formulated O-ring compresses to create a perfect, watertight seal.
Q: Do I need tools to connect SharkBite fittings?
A: No tools are required for connecting SharkBite fittings though the SharkBite Deburr & Gauge Tool is recommended for de-burring and measuring the depth of the pipe. The pipe must be cut square, deburred and free of debris before installing.
Q: Do you need the Disconnect Clip to remove a SharkBite fitting?
A: Yes, the Disconnect Clip is required to remove a SharkBite fitting. Disconnect Tongs are also available to remove the fitting if the connection is in a confined or hard to reach space where a Disconnect Clip is not possible to use.
Q: Is a SharkBite fitting re-usable?
A: Yes, fittings can be reused for testing purposes, but any fitting used repeatedly for testing must not then be used in a permanent installation.
Q: Can a SharkBite fitting be rotated on the pipe?
A: Yes, the fitting can be rotated after assembly and will not affect the integrity of the joint.
Q: Can I use SharkBite fittings for anything other than potable water (e.g, air, gas, oil, etc.) applications?
A: No, fittings are only certified for potable water installations.
Q: What are the maximum temperature and pressure ratings for SharkBite fittings?
A: SharkBite fittings are certified to 200 PSI and 200°F (93°C).
Q: What types of pipe can SharkBite fittings be used with?
A: SharkBite fittings are certified for use with:
- Copper pipe hard drawn Type K, L and M and annealed Type M not to exceed 3/8 nominal, complying with ASTM B88
- PEX pipe complying with ASTM F 876 or CSA B137.5
- CPVC pipe complying with ASTM D 2846 or CSA B137.6
- PE-RT pipe complying with ASTM F 276
Q: Can SharkBite fittings be used with soft Copper or rolled Copper?
A: No, SharkBite fittings can only be used with hard drawn Copper Types K, L, and M.
Q: Can the tube liner be removed?
A: Yes, the tube liner can easily be removed by pulling it past the O-ring, then with the aid of the SharkBite Disassembly Clip or Disconnect Tongs (both sold separately). The tube support liner can drop out of the fittings as it can move freely past the grab ring. Needle nose pliers may be used to pull the tube support liner out.
NOTE: The tube liner is necessary for use with PEX Pipe. It is not required for Copper or CPVC, however, it is not necessary to remove the tube liner from the fitting.
Q: What is the insertion depth for the SharkBite fittings?
A: Insertion depth will depend on the size of the fitting.
- 1/4″ Pipe Insertion Depth = 13/16″
- 3/8″ Pipe Insertion Depth = 15/16″
- 1/2″ Pipe Insertion Depth = 15/16″
- 5/8″ Pipe Insertion Depth = 1-1/8″
- 3/4″ Pipe Insertion Depth = 1-1/8″
- 1″ Pipe Insertion Depth = 1-5/16″
Q: What should I do if a SharkBite system is leaking upon installation?
A: In general, SharkBite fittings only leak due to one of three reasons:
- The pipe was not properly deburred prior to installation.
- The pipe was not properly inserted.
- The pipe was not squarely cut.
Q: How well do SharkBite joints hold up in freezing temperatures?
A: Copper water systems should not be allowed to freeze. When water freezes, it expands and creates pressure that exceeds plumbing system pressure capabilities, i.e. pipes and fittings burst.
Q: How far away from a SharkBite joint do I need to be in order to solder?
A: It is recommended to solder any joints prior to installing a SharkBite fitting. The heat from the torch can be transferred through the pipe and potentially damage the O-ring.
Q: Are SharkBite fittings certified for hydronic heating applications?
A: Yes, SharkBite fittings can be used for hydronic heating applications if the temperature does not exceed 200°F.
NOTE: Glycol mixture for hydronic is acceptable up to and including 100%.
Q: What is the difference between red, white, blue and orange colored PEX Pipe?
A: Red, white and blue Potable Water PEX Tubing are exactly the same material and are certified for potable water applications. The different colors provide the ability to easily distinguish between hot and cold lines. The orange pipe is an oxygen barrier PEX Pipe used only for hydronic heating applications.
Q: What is the insertion depth for the SharkBite 2XL fittings?
A: Insertion depth will depend on the size of the fitting.
- 1-1/4″ Pipe Insertion Depth = 2″
- 1-1/2″ Pipe Insertion Depth = 2-1/4″
- 2″ Pipe Insertion Depth = 2-1/2″
Q: Do you need a tube liner with the 2XL SharkBite fittings?
A: Yes, a tube liner is required when using the SharkBite 2XL fittings in conjunction with PEX pipe. The 2XL PEX tube liners are sold separately.
Q: Are SharkBite fittings approved for use within a concealed wall?
A: SharkBite push-fit fittings are certified for use within a concealed wall, but consulting with local plumbing codes is recommended for specific applications. It is also recommended to pressure test the system prior to sealing up the wall.
Q: Are SharkBite fittings approved for underground use?
A: SharkBite Universal fittings are suitable for burial in most applications; however care is required when using fittings in applications that require burial to ensure the correct installation practices are used and due care is given to any environmental factors that may have a detrimental effect on the life expectancy of the fittings and pipe. The installation of SharkBite Universal fittings in applications that will require the burial of the fitting must comply with all local plumbing code requirements. SharkBite Universal fittings and SharkBite PEX are not suitable for use in areas where the soil is or may become contaminated* including the soil used for back filling. All SharkBite Universal fittings with brass bodies must have an impervious barrier between the fitting and the surrounding soil. Self-fusing, formaldehyde and chloride-free, fully cured silicone tape with a minimum thickness of 0.020″ should be used for this purpose. The soil used for back filling must be free of rocks, debris or any sharp objects that may cause damage to the fitting or pipe through impact or abrasion.
Q: Can I use SharkBite fittings as a dielectric union?
A: No, the standard SharkBite fittings (i.e. Coupling, Elbow, Tee) cannot be used as a dielectric union. The SharkBite Stainless Steel Braided Flexible Coupling Hoses can be used as a dielectric union.
Q: What standards and codes do SharkBite fittings comply?
A: SharkBite fittings are certified to ASSE 1061, NSF/ANSI 61, NSF/ANSI 14 and NSF/ANSI 372. They are listed by IAPMO and CSA. SharkBite fittings are compliant with the Uniform Plumbing Code (UPC), National Plumbing Code of Canada and the International Plumbing Code (IPC). Since local code varies by area, please consult with local plumbing codes for specific applications.
Q: How long can the SharkBite fittings last?
A: SharkBite fittings and PEX pipe carry a 25-year warranty against any manufacturer’s defect as long as the item has been installed in accordance with the installation instructions and complies with local code.
For more information, read our full SharkBite Warranty.
Q: How much pipe needs to be removed to install a SharkBite push-to-connect fitting?
A: To determine how much pipe needs to be removed, take the overall length of the fitting and subtract the insertion depth for both sides. This will leave you with the length of pipe that needs to be removed. A pipe insertion depth chart is available in the SharkBite Installation Guide.
Different rules apply to slip fittings.
1/2″ coupling (Part# U008LF)
Fitting Length = 2″
Insertion depth = 15/16″ (0.9375″)
2″ – (2 X 0.9375″) = 1/8″ (0.125″) can be removed
