Double Wall Interior Stove Pipe

The double-wall, air-insulated design of DVL reduces clearances to combustibles from 18 inches to 6 inches, the closest clearance to a wall of any connector pipe. DVL improves stove performance by keeping flue gas temperatures high for a strong, consistent draft.

Because the inner wall is stainless steel, the flue heats up faster, stays hotter, reduces creosote formation, and has the same lifespan as the chimney. Cutting or crimping is unnecessary with adjustable lengths.

Double wall heating solutions in our catalog are from the leading brand DuraVent.

Whether you need a double wall pipe for a flue outlet or a snap lock adapter for chimney systems, we have all the options available to you.
