Selkirk 207148u Type Ht Insulated Chimney Pipe 7x9x48 in

Product Description

The SELKIRK 207148u is a Type HT insulated chimney pipe section from the Ultra-Temp UT Series, engineered for high-temperature venting applications in residential and light commercial heating systems. Constructed from 430 stainless steel, this pipe section measures 7 inches inner diameter by 9 inches outer diameter and 48 inches in length. The insulated design maintains flue gas temperatures to support proper draft and reduce creosote buildup risk. Licensed HVAC and chimney professionals use this component when building or extending listed chimney systems on high-efficiency and conventional heating appliances.

This pipe section is suited for installations requiring a Type HT rated chimney system, typically paired with gas, oil, or solid-fuel appliances that demand high-temperature-rated venting. The 48-inch length makes it a standard run section for multi-story or attic-pass chimney assemblies. It integrates within the UT Series product family, allowing combination with matching elbows, supports, and termination caps of the same diameter and series.
