GREENSEAM

GREENSEAM is a manufacturer of sheet-metal ducting components designed for low-pressure air movement systems. The product line includes elbows, reducers, snap-lock pipes, and tee joints, all fabricated from galvanized steel in 26-gauge thickness. Components are available in diameters ranging from 4 inches to 14 inches, with press-fit connections that use EPDM or co-polymer seals to maintain airtight joints at a maximum pressure rating of 2 inches water column (in wc). This pressure rating is typical for residential and light commercial HVAC exhaust, ventilation, and combustion-air ducting applications where static pressure does not exceed 0.5 kPa. GREENSEAM fittings are manufactured to standard dimensional tolerances that allow direct integration with other press-fit ductwork systems. The elbows feature a 90-degree angle with a centerline radius equal to the duct diameter, minimizing turbulence and pressure drop. Reducers are concentric, enabling smooth transitions between duct sizes without abrupt area changes. Snap-lock pipes are supplied in 60-inch lengths with longitudinal seams that lock mechanically, reducing the need for additional fasteners. Tee joints provide a 90-degree branch takeoff with equal inlet and outlet diameters. 3G Electric stocks a comprehensive range of GREENSEAM ducting components, ensuring availability of common sizes and configurations for maintenance, retrofit, and new-installation projects. Engineers and procurement specialists can specify these components for systems where corrosion resistance, ease of assembly, and predictable airflow performance are required. The press-fit connection system reduces installation time compared to traditional slip-and-drive or flanged joints, and the EPDM seals provide a durable barrier against moisture and temperature variations typical in HVAC environments. All GREENSEAM products supplied by 3G Electric are new, factory-manufactured units with traceable part numbers for accurate ordering and inventory management.

Frequently asked questions

Common questions about GREENSEAM from 3G Electric.

What is the maximum pressure rating for GREENSEAM ducting components?

GREENSEAM ducting components are rated for a maximum pressure of 2 inches water column (in wc), which is approximately 0.5 kPa. This rating is suitable for low-pressure HVAC exhaust, ventilation, and combustion-air systems. For applications requiring higher static pressure, alternative ductwork with reinforced joints or heavier-gauge material should be considered.

What connection type do GREENSEAM elbows and reducers use?

All GREENSEAM elbows, reducers, snap-lock pipes, and tee joints use a press-fit connection type. This design allows the male end of one component to be inserted into the female end of another, creating a mechanical joint that is sealed with an integrated gasket—EPDM for snap-lock pipes and co-polymer for tee joints. No additional fasteners or sealants are required for standard installations.

What material and gauge are GREENSEAM duct fittings made from?

GREENSEAM duct fittings are fabricated from galvanized steel with a material thickness of 26 gauge (approximately 0.0187 inches or 0.475 mm). The galvanized coating provides corrosion resistance suitable for indoor HVAC environments. The 26-gauge thickness balances structural rigidity with ease of handling during installation.

What sizes are available for GREENSEAM duct reducers?

GREENSEAM duct reducers are available in several size combinations, including 8-inch inlet to 4-inch outlet, 10-inch inlet to 6-inch outlet, 12-inch inlet to 6-inch outlet, 12-inch inlet to 8-inch outlet, and 14-inch inlet to 8-inch outlet. All reducers are concentric and have a press-fit connection on both ends. The length varies by size, typically 6 to 10 inches.

Does GREENSEAM offer snap-lock pipes with pre-installed seals?

Yes, GREENSEAM snap-lock pipes (model GR60SPBGP4GA26 for 4-inch diameter) come with an EPDM seal material integrated into the press-fit joint. The pipe is 60 inches long and made from 26-gauge galvanized steel. The snap-lock seam runs the length of the pipe, providing a rigid structure without requiring separate locking tabs or screws.

What is the centerline radius of GREENSEAM 90-degree elbows?

GREENSEAM 90-degree elbows have a centerline radius equal to the duct diameter. For example, the 9-inch diameter elbow (model GRAE990GA26) has a centerline radius of 8.5 inches, which is approximately equal to the duct diameter. This radius minimizes airflow resistance and is standard for low-pressure duct systems.
