6" x 2' Rigid Chimney Liner, Stainless Steel

Professional Venting Solution – Z-Flex Rigid Chimney Liner for Multi-Fuel Applications

The Z-Flex 2ZR321F0602 Rigid Chimney Liner provides a dependable venting option for contractors working with gas, oil, or wood-burning appliances. Built from 24-gauge stainless steel, this 6-inch diameter, 2-foot section is designed for durability, consistent draft performance, and long-term safety in chimney and venting installations.

With precision-formed seams and corrosion-resistant construction, this rigid liner ensures secure connections while minimizing leakage and airflow disruption. It is engineered to meet the demands of professional HVAC and plumbing contractors requiring a code-compliant solution that performs under varied site conditions.

Advantages of the Z-Flex Rigid Chimney Liner

• Fuel Versatility: Rated for gas, oil, and wood-burning systems (insulation required for wood applications).
• Durable Stainless Steel: Resists corrosion, condensate, and high-temperature operation.
• Precision Seam Construction: Fusion-welded seams provide a smooth interior wall and tight joint alignment.
• Rigid Performance: Maintains shape during installation, offering a straighter path compared to flex liners.
• Long Service Life: Built for reliability in residential and light commercial venting projects.

Technical Specifications

Installation Notes

While the Z-Flex rigid liner is manufactured for easier section-to-section assembly, installation should be completed by a licensed HVAC or chimney professional. Proper sealing, mechanical fastening, and insulation (where required) are critical for safe operation and code compliance. Contractors should follow NFPA 211 and local mechanical code requirements during installation.

Contractor Considerations

On the job site, this rigid liner provides a stable, durable alternative to flexible venting. Its strength minimizes deformation during handling, while its smooth interior surface helps maintain draft efficiency and reduces soot accumulation. For wood-burning systems, insulation sleeves or wrap must be applied to maintain safety clearances.

The Z-Flex Rigid Chimney Liner is built for professionals who demand venting products that perform reliably under field conditions, offering both durability and compliance in one solution.
