45° ELBOW SINGLE WALL BLACK PIPE - 6"Ø SP00090

This 6" single wall black pipe elbow requires a minimum clearance of 18 inches to all combustible materials including walls, ceilings, wood mantles, furniture, and any other flammable surfaces. This clearance must be maintained in all directions around the elbow. If you need to install closer to combustibles, consider upgrading to double wall stove pipe which only requires 6 inches of clearance.

No, single wall black stove pipe elbows cannot be run through walls or ceilings under any circumstances. They are designed exclusively for use in open interior spaces as a connector between your wood stove and a Class-A insulated chimney system. Single wall pipe should also not be used outdoors where exposed to weather elements. For wall or ceiling penetrations, you must use approved Class-A insulated chimney pipe with proper thimbles and support systems.

A 45-degree elbow provides better airflow and draft compared to a 90-degree elbow because it creates less restriction in the flue path. The gentler angle reduces turbulence and allows smoke and gases to flow more smoothly. When possible, it's often better to use two 45-degree elbows instead of one 90-degree elbow to maintain optimal draft. However, a straight vertical installation is always best, and elbows should only be used when necessary to navigate around obstacles.

This elbow is manufactured from 22-gauge cold-rolled steel, which is approximately 27% thicker than cheaper 24-gauge alternatives and provides superior durability and heat resistance. The heavier gauge steel resists warping under high temperatures, maintains its shape better over time, and offers improved structural integrity. The welded construction (rather than seamed or crimped) further enhances strength and eliminates potential leak points or separation issues.

Yes, this 6-inch 45-degree elbow is designed with universal compatibility and will connect with any brand of 6-inch diameter single wall black stove pipe. The precision end forming ensures a tight, secure fit pipe-to-pipe regardless of manufacturer. It can also be connected to Class-A insulated chimney pipe using the appropriate adapter. The pre-drilled holes accommodate standard metal screws for secure attachment between sections.

The high-temperature black paint comes factory-applied and does not require any special preparation before installation. However, during the first few fires, you may notice a slight odor as the paint fully cures under heat. This is normal and will dissipate after the initial burn-in period. The paint is formulated to resist chipping, peeling, and fading throughout the life of the pipe, maintaining its attractive matte black finish even under continuous high-temperature operation.

The elbow comes pre-drilled with holes and includes metal screws for securing it to adjacent pipe sections. The unit arrives fully assembled and ready to install - you do not need to purchase any additional hardware for basic installation. However, you may want to purchase high-temperature silicone sealant for extra security at joints, and you'll need appropriate Class-A chimney pipe, ceiling support boxes, and wall thimbles depending on your complete installation requirements.

Regular maintenance involves inspecting the elbow annually (or more frequently with heavy use) for creosote buildup, which should be brushed out during chimney cleaning. Check all connections to ensure screws remain tight and joints are secure. Inspect for any signs of warping, rust, or deterioration, particularly at seams. Because single wall pipe gets very hot during operation, always allow it to cool completely before inspection or maintenance. If significant corrosion or damage is present, replace the elbow immediately to maintain safe operation.
