10" x 6" Smoke Pipe Duct Increaser/Reducer, Tapered, 26GA

Lukjan 10" x 6" Galvanized Smoke Pipe Duct Increaser/Reducer

The Lukjan 10" x 6" increaser/reducer is a precision-formed galvanized steel fitting designed for transitions between duct diameters in HVAC air distribution systems. Fabricated with lock-forming quality galvanized sheet steel, it ensures durability, code compliance, and efficient airflow performance in both new installations and retrofit projects.

Application

This tapered fitting is suitable for residential, commercial, and light industrial HVAC systems. It facilitates smooth transitions between 10" and 6" duct sizes, minimizing turbulence and static pressure losses while maintaining consistent air distribution through supply or return runs.

Performance Characteristics

• Material: 26-gauge galvanized steel
• Nominal Sizes: 10" to 6"
• Length: 5 inches
• Coating: G-30 galvanized finish per ASTM-A653 CS Type B
• Configuration: Non-crimped tapered profile

Installation Guidelines

Install in accordance with SMACNA duct construction standards. Joints should be secured with appropriate sheet metal screws and sealed with UL-listed duct sealants or tapes to ensure airtight connections. Adequate mechanical supports must be provided at code-required intervals to prevent sagging and preserve duct alignment.

Advantages

• Code-Compliant Fabrication: Meets ASTM-A653 specifications for galvanized sheet steel.
• Durable Construction: Corrosion-resistant steel ensures long service life.
• Efficient Airflow: Tapered transition reduces system resistance and noise.
• Professional Grade: Manufactured for contractor applications in engineered HVAC systems.

The Lukjan 10" x 6" smoke pipe duct increaser/reducer is a contractor-grade fitting engineered for long-term performance. With its heavy-duty galvanized construction and precise sizing, it provides a reliable solution for duct transitions in demanding HVAC environments.
