PLASTIC SUPPLY

PLASTIC SUPPLY is a manufacturer of PVC duct components used in industrial ventilation, fume extraction, and dust collection systems. The product line includes duct couplers and flange adapters in nominal duct diameters from 4 inches through 16 inches, with additional sizes available across the full catalog. These components are designed to join sections of PVC ductwork and connect duct runs to flanged fittings, fans, and other system elements. The couplers are sized with inlet and outlet diameters that correspond to the nominal duct size, and overall lengths vary by diameter: the 4-inch coupler has a 4 1/4-inch overall length, while the 6-inch through 16-inch couplers share a 5 7/8-inch overall length. Flange adapters, such as the 14-inch model, have an 18-inch overall length and a flange inner diameter matched to the duct size. All components are constructed from PVC, which provides resistance to corrosion and chemical attack in airstreams containing moisture, vapors, or light particulates. The couplers and flanges are intended for low-pressure ventilation and exhaust applications, where a secure, leak-resistant joint is required. 3G Electric supplies the PLASTIC SUPPLY line as part of its catalog of industrial equipment, offering 96 SKUs of pipe fittings, flanges, and duct components. The product range covers common nominal duct sizes, allowing maintenance and procurement teams to source couplers and flange adapters for new installations or replacements without custom fabrication. Each item is identified by a manufacturer part number, such as PVCC16 for the 16-inch coupler or PVCF14 for the 14-inch flange adapter, which simplifies cross-referencing and reordering. 3G Electric supports the line by providing specification data, dimensional details, and availability information for each SKU, enabling buyers to verify fit and compatibility before purchase. The components are suitable for integration with standard PVC duct systems and are typically used in applications where metal ducting would be susceptible to corrosion or where lightweight, non-sparking material is preferred. Because the couplers and flanges are produced in a range of sizes, they can accommodate ductwork layouts that require transitions between sections or connections to equipment with flanged inlets or outlets. The PVC construction also allows for solvent welding or mechanical fastening, depending on the installation requirements. 3G Electric maintains inventory and sourcing capabilities for the PLASTIC SUPPLY line, serving industrial facilities that require reliable duct components for air handling, fume control, and particulate transport. The catalog includes couplers for 4, 6, 8, 10, 12, 14, and 16-inch duct diameters, with corresponding flange adapters for select sizes. This coverage addresses many common duct sizes encountered in ventilation and exhaust systems, reducing the need for adapters or custom parts. For plant engineers and maintenance managers, the availability of dimensional data and part numbers supports accurate specification and efficient procurement. 3G Electric’s role is to make these components accessible globally, with the technical information needed to select the correct size and configuration for a given duct system.

Frequently asked questions

Common questions about PLASTIC SUPPLY from 3G Electric.

What sizes of PLASTIC SUPPLY duct couplers are available?

PLASTIC SUPPLY duct couplers are available for nominal duct diameters of 4, 6, 8, 10, 12, 14, and 16 inches. The 4-inch coupler (PVCC04) has a 4 1/2-inch inlet and outlet diameter and a 4 1/4-inch overall length. The 6-inch through 16-inch couplers (PVCC06, PVCC08, PVCC10, PVCC12, PVCC14, PVCC16) have inlet and outlet diameters that match the nominal size and a 5 7/8-inch overall length. These sizes cover many common ventilation and exhaust duct systems.

What is the difference between a PLASTIC SUPPLY duct coupler and a flange adapter?

A PLASTIC SUPPLY duct coupler joins two sections of PVC duct of the same nominal diameter, providing a straight connection. A flange adapter, such as the 14-inch model (PVCF14), connects PVC ductwork to a flanged fitting or equipment. The flange adapter has a longer overall length (18 inches for the 14-inch size) and a flange inner diameter (13 5/8 inches for the 14-inch size) that matches the duct size. Both are made of PVC and are used in low-pressure ventilation and fume extraction systems.

What are the typical applications for PLASTIC SUPPLY PVC duct components?

PLASTIC SUPPLY PVC duct couplers and flange adapters are used in industrial ventilation, fume extraction, and dust collection systems. They are suitable for moving air or lightweight particulates in low-pressure applications. The PVC construction provides resistance to corrosion and chemical attack, making these components appropriate for airstreams containing moisture or vapors. They are commonly installed in ductwork that connects to fans, scrubbers, or other air handling equipment where a secure, leak-resistant joint is required.

How do I select the correct PLASTIC SUPPLY coupler for my ductwork?

To select a PLASTIC SUPPLY coupler, determine the nominal duct diameter of your existing ductwork. The coupler is sized to match that nominal diameter, with inlet and outlet dimensions that correspond to the duct size. For example, a system with 8-inch duct requires the PVCC08 coupler, which has 8 5/8-inch inlet and outlet diameters. Verify the overall length to ensure it fits the available space. For connections to flanged equipment, choose a flange adapter with the matching duct diameter and flange inner diameter.

Are PLASTIC SUPPLY duct couplers suitable for high-temperature applications?

PLASTIC SUPPLY duct couplers are made of PVC, which has temperature limitations. They are intended for low-pressure ventilation and exhaust systems where the airstream temperature is within the service range of PVC. For high-temperature applications, alternative materials such as metal or high-temperature plastics should be considered. Consult the manufacturer’s specifications for the maximum continuous operating temperature of PVC in duct applications.

What part numbers correspond to PLASTIC SUPPLY duct couplers and flange adapters?

PLASTIC SUPPLY uses a part numbering system that indicates the component type and size. Duct couplers are identified by the prefix PVCC followed by the nominal duct diameter in inches: PVCC04 (4-inch), PVCC06 (6-inch), PVCC08 (8-inch), PVCC10 (10-inch), PVCC12 (12-inch), PVCC14 (14-inch), and PVCC16 (16-inch). Flange adapters use the prefix PVCF followed by the nominal duct diameter, such as PVCF14 for the 14-inch flange adapter. These part numbers simplify ordering and cross-referencing.
