Buying Guide: Key Purchase Considerations
- Material compatibility: Ensure the compound is suitable for PVC, CPVC, ABS, and any metals involved in your piping system. Some formulas are optimized for plastic-to-plastic joints, while others handle mixed materials more effectively.
- PTFE content: PTFE pastes deliver superior lubricity and leak resistance. Choose PTFE-based products when threads require smoother disassembly and reduced friction during installation.
- Non-hardening behavior: Non-hardening compounds are preferred for systems that may require future disassembly, such as irrigation or retrofit projects.
- OTF and temperature range: Consider the operating temperatures and pressures you anticipate. Some formulas tolerate higher temperatures or pressures, while others are designed for standard residential use.
- Safety and odor: For indoor or occupied spaces, opt for low-odor, non-toxic formulations to minimize exposure during application and cure time.
- Ease of cleanup: Blue or gray PTFE-based compounds often clean up easily and leave little residue, which is helpful during multi-joint assemblies.
- Application method: Some products come with brushes or specialized applicators. Choose based on how easy it is to reach tight or awkward threaded joints.
- Certifications: NSF certification and other approvals provide confidence for potable water and gas line applications. Verify compliance with local codes when necessary.
