Plasti-Bond PVC-coated fittings protect conduit thread exposure at points of connection. Plasti-Bond fittings offer the most effective way of protecting your electrical systems and providing the best available corrosion protection. Plasti-Bond Form 8 fittings carrying the UL 514B and UL Type 4X listing and IEC IP69 rating. Our V-Seal® gasket, with special interlocking “V” groove prevents corrosion damage by sealing PVC coated Form 8 Conduit Bodies, sizes 1/2″ to 4″. In addition, Plasti-Bond Form 8 fittings have stainless steel encapsulated screws which seal around each screw opening. All fittings also feature PVC sealing sleeves which are sized to fit tightly over the coated conduit when assembled, therefore protecting the threaded joints.
Plasti-Bond’s line of PVC-coated hazardous location (classified) conduits and fittings are UL 1203 listed, including Sealing Fittings, Conduit Unions, GUA Outlet Boxes and EC Series Flexible Couplings.
All PVC-coated galvanized rigid conduit is not created equal. The biggest difference is ETL PVC-001 verification. All major PVC-coated conduit brands comply with standards for safety as established by UL 6, but only ETL PVC-001 validates coating performance and predicts product life. Plasti-Bond consistently earns its ETL PVC-001 label by successfully passing the stringent ASTM D870 and ASTM D2247 tests required for verification each quarter. If your raceway conduit doesn’t carry an ETL PVC-001 verified label, those systems may be at risk for premature product failure.
Plasti-Bond’s PVC-coated conduit offers long-term reliability and protection from costly corrosive attacks in harsh locations and corrosive environments. Our specially formulated PVC coating ensures that corrosives never touch the metal and protects conductors from damage. The exclusively developed exterior coating is UV stabilized, dramatically reducing UV degradation in outdoor applications. Our polyurethane interior coating protects our conduit from corrosion and chemicals while also allowing optimum durability and friction-reduced wire pulls. Plasti-Bond PVC conduit is coated in a 40-mil grey PVC exterior coating with a 2-mil urethane interior coating.
All coatings are permeable and without a strong adhesive bond to a conduit’s steel substrate, the product will surely fail. Loss of adhesion allows moisture inside the coating, putting the metal in direct contact with corrosive elements. This limits the coated conduit’s lifespan and speeds up its failure. Plasti-Bond’s tested adhesive bond is proven to adhere and protect substrate from corrosive damage and harsh environmental elements.
All manufacturers pay for product testing or UL testing and listings. Adhesion testing helps ensure electrical raceways in harsh environments receive maximum corrosion protection. Plasti-Bond and the competition both participated in a nationally recognized ASTM accelerated life-cycle test. Samples of each conduit were placed in boiling water for an equal amount of time. Afterwards, matching cuts were made in the PVC coatings. Then, a tab was pulled with a pair of pliers to determine adhesive strength. Plasti-Bond’s adhesive bond held and did not expose the substrate to corrosion. The competition’s adhesive bond failed and completely separated from the steel substrate.

Industry-accepted ASTM testing is specifically intended to evaluate product performance for humidity and heat – the two most common conditions affecting the adhesive bonds of protective coatings. The use of high-temperature boiling water consistently recreates extreme conditions for proper accelerated testing.
Plasti-Bond’s proprietary Adhesion Enhancement Process (AEP) prepares the zinc surface of conduit to enable a degree of coating adhesion not achieved by other manufacturers. AEP removes oxidation, white rust and contaminates from the outer surface. This prepares the zinc surface for optimum adhesion without degrading it. After PVC coating, trimming and final surface preparation, the clean pipe threads are hot-galvanized using specially designed 3-axis robotic arms to apply a consistent zinc protection. This process maintains the integrity of the threads and the end result is superior PVC bonding to the metal, as well as consistent corrosion protection on the zinc coated threads.
Plasti-Bond PVC-coated conduit features an internal polyurethane coating designed for optimum chemical resistance and durability, providing maximum protection for the inner conduit substrate. In addition, friction is reduced allowing for easy wire pulls.
As a leader of PVC-coated rigid metal conduit, Plasti-Bond offers a complete system of proven premium corrosion protection and provides an unmatched level of safety for electrical raceways systems in harsh locations and corrosive environments. Plasti-Bond is also cost-competitive and readily available when and where you need it at your worksite.
Plasti-Bond utilizes a UV-stabilized PVC coating specially formulated to prevent deterioration when exposed to outdoor environments.
After PVC coating of the conduit, Plasti-Bond’s automated ProTECH process uses a laser trimming operation to remove excess PVC from the conduit ends. Next, the mechanical surface of chemically cleaned conduit threads is prepared. This is critical for a strong bond. Then, the clean pipe threads are hot-galvanized using specially designed equipment, including 3-axis robotic arms. After hot-galvanizing, the threads are coated with a clear polyurethane spray, protecting the galvanized thread from corrosive attack.
Plasti-Bond’s factory nipples and elbows offer comprehensive sizes and configurations, including standard and special radius elbows, ready for quick shipment. This helps eliminate labor delays and cost and enables faster installation.
Plasti-Bond’s Form 8 condulet bodies are now certified Type 4X by UL and have earned IEC’s IP69 rating. Our patented V-Seal gasket provides the most effective seal for PVC-coated Form 8 conduit bodies (sizes 1/2″ to 4″) and Mark 9 fittings. Plasti-Bond’s special V-shaped interlocking groove ensures a strong defense against the ingress of dust, water and other foreign matter. Plus, all Form 8 cover screws are made from stainless steel with a plastic encapsulated head for an optimal seal around the screw opening.
The molded ribs on Plasti-Bond couplings provide an extra thickness of PVC that protects the coating from cuts and abrasions caused by the teeth of wrenches and other installation tools.
All Plasti-Bond clamps, along with pipe straps, clamps and clamp-back spacers, are designed specifically for PVC-coated conduit to ensure proper fit and ease of installation.
Thread protectors are color-coded for quick identification of conduit size.
Properly installing a PVC-coated conduit system using manufacturer recommendations and specified tools contribute to a faster, damage-free installation. This will protect your investment and safeguard product service life. If unmodified standard tools are used instead, coating damage could occur and result in unnecessary costs and lost time.
Plasti-Bond offers an array of tools specifically designed for the installation of its PVC-coated conduit and fittings. Click here for Plasti-Bond’s list of manufacturer recommendations and here for installation tools.
Our five-year warranty provides additional peace of mind, even after completed installation.
Sealing sleeves are important because they keep corrosive elements from entering the interior of a conduit system at threaded joints. Plasti-Bond’s PVC sleeves are sized so they fit tightly over the coated conduit when assembled.
