When To Remove the Plastic Insert in SharkBite Fittings
The plastic insert inside SharkBite fittings serves an important function by reinforcing the fitting and preventing the pipe from deforming when inserted. However, there are specific situations when removing this plastic insert is necessary or beneficial.
Typically, the plastic insert should be removed when connecting SharkBite fittings to certain types of pipe or tubing. Here are the main scenarios:
- Using PEX or CPVC pipe: These materials are softer and more flexible, and the plastic insert is usually left in place to provide support and ensure a secure seal.
- Connecting to copper pipe: For copper pipes, especially those with a thicker wall or if the pipe is being inserted into a fitting with a compression ring, removing the plastic insert can help achieve a better grip and reduce the risk of damaging the pipe.
- When using SharkBite fittings as adapters: If the fitting is being used in conjunction with other adapters or specialized connections, the insert may need to be removed to accommodate different insertion depths or pipe diameters.
- For retrofit or repair applications: In some retrofit cases, the insert may hinder proper seating of the pipe or cause alignment issues, warranting its removal.
Removing the plastic insert is not generally recommended unless the manufacturer’s instructions or the specific application call for it. Incorrect removal or leaving the insert out when it is needed can compromise the seal and cause leaks.
How to Properly Remove the Plastic Insert
If removal of the plastic insert is necessary, it should be done carefully to avoid damaging the fitting or the pipe. Follow these expert steps to safely remove the insert:
- Use the right tools: A small flathead screwdriver or needle-nose pliers work well for prying the insert out without deforming the fitting.
- Work gently: Insert the tool under the edge of the plastic insert and slowly lift it out, taking care not to scratch the interior of the fitting.
- Inspect the fitting after removal: Ensure that no plastic fragments remain inside, as these can interfere with the seal.
- Test fit the pipe: Before final assembly, insert the pipe to check that it seats properly and the fitting retains its grip without the plastic insert.
Proper removal preserves the integrity of the fitting and maintains the SharkBite’s reliable connection.
Impact of Removing the Insert on Seal Integrity
Removing the plastic insert alters the internal structure of the SharkBite fitting. This can affect the sealing mechanism in subtle ways:
- The plastic insert provides a firm backing for the O-ring, ensuring consistent compression around the pipe.
- Without the insert, the pipe may deform slightly under the compression ring, potentially leading to a less uniform seal.
- In some materials, the absence of the insert can reduce the risk of pipe damage or cracking caused by excessive internal pressure.
The decision to remove or retain the insert should balance these factors based on pipe material, system pressure, and manufacturer recommendations.
| Pipe Material | Insert Removal Recommended? | Reason |
|---|---|---|
| PEX | No | Insert supports softer pipe, ensuring proper seal |
| CPVC | No | Insert prevents pipe deformation and maintains grip |
| Copper (thin wall) | Usually No | Insert adds support, but depends on pipe condition |
| Copper (thick wall) | Yes | Removing insert improves grip and prevents pipe damage |
| Retrofit/Adapter Use | Depends on application | May be necessary for alignment or fitment reasons |
