Based on the provided reference, grip fittings are used to connect PVC (Polyvinyl-Chloride) tubing to copper pipe.
Understanding Grip Fittings for PVC to Copper
The reference specifically states that rigid plastic PVC tubing can be joined to copper using "grip fittings." This type of fitting is designed to create a secure and sealed connection between different pipe materials like plastic and metal.
According to the reference, each side of a grip fitting incorporates key components to ensure a tight seal:
- A narrow grip ring to hold onto the pipe.
- A plastic compression ring or a rubber O-ring that forms the necessary seal to prevent leaks.
These fittings work by compressing the ring against the pipe material, creating a watertight connection without the need for adhesives or soldering, making them a useful option for transitioning between PVC and copper.
Practical Considerations
The reference also includes a useful tip related to maintenance with these fittings:
- Use penetrating oil to help loosen corroded mounting nuts, which can be helpful when working with existing installations or making adjustments.
