4-Inch Adjustable Slip Joint Connector

This 4-inch slip joint connector is an adjustable single-wall connector-pipe section that provides approximately 4 to 8 inches of usable adjustment. It is made from 26-gauge black-finished stainless steel with seamless welded construction.

The slip joint is useful when fixed-length connector pipe leaves a small gap between the appliance and the chimney transition. Instead of adding another full pipe section, the adjustable connector lets you fine-tune the final connector length where that type of connection is permitted.

Compatibility and Safety

Use this slip joint only with a compatible 4-inch connector-pipe system and only where adjustable single-wall connector pipe is permitted by the appliance and installation instructions. Verify the required overlap, fastening method, clearances, and connector configuration before use.

Do not use single-wall connector pipe as a substitute for listed insulated chimney through walls, ceilings, roofs, attics, or other building penetrations.
