4. Installation Guide
Follow these steps for proper installation of your Fernco QC-4.75 Qwik Cap:
- Measure Pipe: Before installation, accurately measure the outside diameter (OD) of the pipe socket you intend to cap. Ensure it falls within the cap's compatible range of 4.32" - 5.05" OD. The cap's internal diameter (ID) is 4.82".
- Prepare Pipe: Ensure the pipe end and socket are clean and free from debris. No primers or glues are required for installation.
- Position Cap: Slide the Qwik Cap directly over the Schedule 40 PVC pipe socket or hub. Ensure the cap is fully seated over the pipe end.
- Tighten Clamp: Use a screwdriver, nut driver, or torque wrench to tighten the 300 series stainless steel clamp. Tighten until the cap is securely fastened and a water-tight seal is achieved. Do not overtighten.

6. Maintenance
The Fernco QC-4.75 Qwik Cap requires minimal maintenance due to its durable PVC construction and corrosion-resistant stainless steel clamp.
- Periodic Inspection: Periodically inspect the cap and clamp for any signs of damage, wear, or loosening.

- Clamp Tightness: If any leaks are detected or the cap appears loose, re-tighten the stainless steel clamp with a suitable tool, ensuring a snug fit without overtightening.
7. Troubleshooting
Most issues with the Qwik Cap can be resolved with simple checks:
- Leakage Around Cap:
- Ensure the clamp is sufficiently tightened.
- Verify that the correct cap size (QC-4.75) is used for the pipe's outside diameter (4.32" - 5.05").
- Check for any damage to the cap or the pipe surface that might prevent a proper seal.
- Cap Does Not Fit:
- Re-measure the outside diameter of your pipe socket. The QC-4.75 is designed for pipes with an OD between 4.32" and 5.05".
- Confirm you are attempting to cap a Schedule 40 PVC socket or one of the other compatible pipe types listed in Section 5.
