Description
CPVC-29 Solvent Cement
Spears® Manufacturing CPVC-29 Solvent Cement is an industrial-grade, extra-heavy-bodied CPVC solvent cement with a slow-setting formulation developed for large-diameter CPVC and PVC piping systems requiring chemical resistance, high gap-filling properties, and additional assembly time.
CPVC-29 is suitable for all classes and schedules of compatible CPVC and PVC pipe and fittings with interference-fit connections through 24" nominal pipe size. Its versatile formulation is particularly useful for chemical piping, large fabricated fittings, and fume and duct applications.

Chemically Resistant Industrial Joining
CPVC-29 is specially formulated for compatible CPVC and PVC systems requiring chemical resistance to demanding services such as caustics, hypochlorite solutions, mineral acids, aggressive water, and aqueous salt solutions.
This industrial-grade formulation makes CPVC-29 a strong choice for chemical-processing and other demanding piping installations where material compatibility, chemical resistance, and properly assembled solvent-cement joints are important.
Extra-Heavy Body & High Gap Fill
The extra-heavy-bodied formulation provides high gap-filling properties for large-diameter piping systems, fabricated fittings, and other compatible connections where a substantial cement body is desirable during assembly.
Proper interference fit and surface preparation remain essential, and CPVC-29 should always be applied according to current Spears® installation instructions and the requirements of the selected CPVC or PVC piping system.
Large-Diameter CPVC & PVC Systems
CPVC-29 is suitable for all classes and schedules of compatible CPVC and PVC through 24" nominal pipe size, providing broad coverage for large industrial piping and fabricated fitting applications.
The slow-setting formulation provides additional working time for applying cement, inserting the pipe, and properly aligning larger components before the completed connection begins to set.
Fume, Duct & Chemical Applications
CPVC-29 is recommended for compatible chemical piping, large fabricated fittings, and fume and duct fittings, making it a versatile industrial solvent cement for applications where both PVC and CPVC components may be encountered.
Always verify material compatibility, nominal pipe size, schedule, chemical service, operating temperature, system pressure, and installation requirements before selecting CPVC-29 for the intended piping system.
Installation & Selection Considerations
- Check the cement before use.
- Keep the container tightly sealed.
- Confirm CPVC or PVC compatibility.
- Verify chemical and operating conditions before installation.
- Follow Spears® joining and cure requirements before placing the system in service.
Review the supplied Spears® documents for additional CPVC-29 specifications, CPVC and PVC compatibility, chemical-resistant applications, large-diameter joining requirements, product standards, handling guidance, and solvent-cement installation information before use.
