Installation & Handling Tips
For the best PVC slip coupling performance, be sure to follow these best practices during installation:
- Cut and deburr pipe ends square for a smooth, flush connection.
- Clean and dry the fitting sockets and pipe surfaces.
- Apply PVC primer and solvent cement (meeting ASTM D2564) to both the pipe and fitting.
- Insert fully with a ¼-turn twist to evenly distribute cement and create a secure seal.
- Hold in place for several seconds and wipe excess cement immediately.
- Allow at least 15 minutes of set time (two hours for full cure before pressurizing).
- Store fittings in a cool, shaded area before use to prevent UV degradation.
Also, make sure to avoid overapplying solvent cement, as excess material can weaken the bond and reduce pressure tolerance.
