Installation & Handling Tips

For strong, long-lasting performance, follow these best practices when installing your Schedule 40 PVC reducer coupling:

• Clean and dry both pipe ends and coupling sockets before assembly.
• Cut pipes squarely and remove any burrs.
• Apply PVC primer to both surfaces, followed by ASTM D2564-approved solvent cement.
• Insert the pipe fully with a ¼-turn twist for even cement distribution.
• Hold in place briefly, then wipe off the excess cement.
• Allow at least 15 minutes for handling and two hours for full curing before pressure testing.
• Avoid twisting the joint after bonding, and be sure to store couplings in a cool, shaded area to prevent UV damage.
