Full selection of performance CPVC duct fittings for superior handling of air, exhaust ventilation and fumes in ductwork systems. Harrison® brand CPVC ductwork fittings available online from PVC Pipe Supplies are an industry leading choice for quality, reliability and resistance against chemicals, corrosion and aggressive environments. CPVC duct fittings are suitable for open air systems only. Duct is not intended for liquids or pressurized gas applications. CPVC duct fittings are rated for service temperatures between 32°F and 200°F (0°C - 93°C). They are commonly used in industrial HVAC applications for new constructions. Available CPVC duct fittings are suited for use in commercial, residential HVAC systems, chemical process control, emission collection equipment such as fume hoods and fume scrubbers, manufacturing plants, medical facilities and many others. Compared to PVC duct, CPVC duct fittings have superior chemical resistance properties. Versus metal ductwork, CPVC duct resists rust, is lighter in weight, easier to support and install, and offers a longer, more cost effective service life for handling air as well as many common fumes and chemical gases.
Available Harrison® CPVC ductwork is manufactured using Corzan® Type IV, Grade 1 rigid, virgin chlorinated polyvinyl chloride (CPVC). Corzan® CPVC materials are within Cell Class 23447 per ASTM D1784 standards. Harrison Machine and Plastic® is a company with over 50 years experience producing durable, consistent, long lasting and cost effective CPVC duct fittings. CPVC duct fittings have high tensile strength, a high modulus of elasticity with low thermal conductivity and electrical conductance. CPVC ducting pipe fittings are tested and report excellent fire and smoke spread resistance. They meet ASTM E-84, ULCS 102.2, UL-723 and UL-94 standards for flame spread rating of 25 or less and a smoke generation of 50 or less for use in return air plenums.
CPVC ductwork fittings are dark grey in color. Fittings come in iron pipe size (IPS) extruded, round duct. CPVC duct comes in IPS sizes from 2" up to 24" and will depend on fitting type. Larger diameter fittings are available on request and can be provided in sizes up to 60" (5 feet) fabricated from rolled stock. Contractor pricing is available to meet contractor job needs. It is recommended to solvent weld systems up to 14" in diameter. A heavy bodied CPVC cement and primer is recommended for installation. Hot air welding is recommended for CPVC duct systems above 14". Available CPVC duct fittings include 45 degree elbows, 90 degree elbows, duct tees, duct wyes, true wye duct fittings, rigid and flex hose duct couplers, duct caps, CPVC pipe hangers, butterfly dampers, blastgates, duct flanges, blind flanges, exhaust hoods, rainskirts, style A rain caps and style B rain caps.
CPVC duct fittings are high performance components specifically designed for use in ductwork and ventilation systems. These fittings are ideal for air handling applications where reliable connections are required to transport air or exhaust fumes. Commonly used to connect, terminate, or change the direction of airflow in duct systems, CPVC duct fittings are known for their durability, chemical resistance, and efficiency. They are constructed from chlorinated polyvinyl chloride (CPVC), offering superior resistance to aggressive environments compared to standard PVC or metal alternatives.
Available in various sizes and configurations, CPVC ventilation fittings allow for seamless routing of ductwork to collection points, filtration systems, fume scrubbers, or exhaust release setups. These fittings are commonly used with CPVC duct pipe for air, exhaust, fume, and vapor handling in industrial, commercial, and manufacturing systems. CPVC duct fittings are for use with open air, non-pressurized applications only and are not suitable for handling liquids or pressurized gases. Always ensure chemical compatibility before use.
CPVC Duct Fitting Sizes and Options
Our selection of CPVC ductwork fittings has been built to meet the needs of HVAC professionals, contractors, facility engineers, and maintenance crews. Fittings are offered in Iron Pipe Size (IPS) standards, with sizes ranging from 2″ to 24″. Large diameter duct fittings up to 60″ can be made to order upon request, fabricated from rolled CPVC stock.
We provide a full set of CPVC industrial duct fittings to suit diverse ductwork installation needs. Options include 45° elbows, 90° elbows, duct tees, duct wyes, true wyes, flexible and rigid duct couplers, duct caps, pipe hangers, butterfly dampers, blastgates, duct flanges, blind flanges, exhaust hoods, rain skirts, and rain caps. Standard connection styles are primarily socket ends for solvent welding or hot air welding installations.

CPVC duct fittings, compared to other materials, have superior resistance to corrosion, chemicals, and environmental wear while offering high tensile strength, low thermal conductivity, and minimal electrical conductance. Their lightweight construction makes them easier to install and support than metal alternatives, all while providing a long service life.
Applications and Uses
CPVC duct fittings are a preferred choice for projects requiring long term reliability and chemical resistance in air handling systems. Common applications include:
- • Industrial HVAC systems
- • Chemical process control
- • Fume hoods and scrubbers for emission collection
- • Manufacturing plants handling chemical exhaust
- • Residential and commercial ventilation systems
- • Medical facilities and laboratories with controlled airflow
- • Dust and particulate collection systems
- • Vapor and volatile organic compound (VOC) management
These fittings are especially suited for environments where aggressive chemicals, fumes, or vapors are present, making them ideal for demanding industrial, manufacturing, and laboratory applications.
Recommended Installation Practices
For installation, CPVC fittings below 14″ in diameter are recommended for solvent welding using a heavy bodied CPVC cement and primer to create airtight connections. For fittings above 14″, hot air welding is recommended to ensure secure joints and minimize leakage risks. Proper installation practices significantly enhance the performance and longevity of duct systems.
Key Features and Benefits
CPVC duct fittings are engineered for superior performance and durability in tough environments. Their key advantages include:
- • Superior Chemical Resistance: Better resistance to harsh chemicals compared to metal or standard PVC.
- • Durable Construction: Designed to withstand environmental, chemical, and thermal stresses.
- • Cost Effective: Lightweight and easy to install, with longer service life and minimal maintenance versus metal ductwork.
