The Types of PVC Glue

PVC Cement

• PVC cement is specially formulated for schedules 40 and 80 PVC pipe. The schedule determines the thickness of the PVC; the larger the number, the thicker the PVC. After you apply the cement, the pipe will visibly soften. It will then solidify as the cement sets to form a joint that is stronger than the surrounding pipe and fittings. Be cautious and avoid any skin contact, since PVC cement is harsh enough to cause chemical burns on sensitive skin. This piping material is generally used in drain, waste and vent (DWV) applications, and not for potable water transport.

CPVC Cement

• Chlorinated polyvinyl chloride (CPVC) cement is for use with CPVC pipe, which is often used in water distribution systems. This cement is very similar to PVC cement. CPVC cement can bond pipe joints without creating hazardous vapors. If CPVC cement has started to thicken, the catalyzing agents have partially evaporated. This results in reduced bonding capability.

ABS Cement

• Acrylonitrile butadiene styrene (ABS) cement is chemically different from the other glues. It is engineered to react chemically with ABS pipe. ABS cement can only be used for ABS piping since it can damage other types of pipes. Pipes can be weakened to the point where they are unable to withstand pressure. ABS pipe is often used for DWV applications.

Transitional Cement

• Transitional cement can be used when connecting different types of plastic pipe, such as ABS and PVC. This cement fuses the two types of the pipe together without causing extreme chemical reactions or creating harmful fumes. Fusion uses heat or solvents to soften the plastic, allowing the pieces to join as if they were one piece.
