The corrosion-resistant stainless steel construction withstands repeated thermal expansion cycles while blocking acidic moisture and creosote deposits that gradually degrade unprotected clay tile or brick flues.\u003c\/p\u003e \u003ch2\u003eSystem Specifications and Fit\u003c\/h2\u003e\n\u003cp\u003eWith a 5-inch clear inner diameter, this liner aligns with common venting requirements for residential heating equipment that demands steady exhaust flow without excessive air restriction. The 25-foot run length accommodates the majority of single-family home chimney heights, spanning typical second-floor appliance installations down to ground-level exits. Sections interlock to form a continuous interior channel, sealing off gaps behind old mortar joints to prevent hazardous gas leakage into living spaces.\u003c\/p\u003e \u003ch2\u003ePerformance and Installation Considerations\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFlexible stainless design navigates minor flue contours while maintaining vertical alignment during pull-through procedures\u003c\/li\u003e\n\u003cli\u003eSecure joint connections maintain consistent draft pressure and reduce heat transfer to adjacent combustible framing\u003c\/li\u003e\n\u003cli\u003eStainless material prevents internal deterioration from wetwood smoke and condensation, extending overall venting lifespan\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eVerify your existing flue clearance and appliance manufacturer specifications before installation.
