TEMCo TH4001 PVC Conduit Heat Blanket Bender
TEMCo’s TH4001 model is designed for 1/2″ to 1 1/2″ conduit, offering a longer heat blanket to create wider bends with ease. A distinctive feature is the thermostat housed outside the blanket, which allows the blanket to wrap more tightly around the conduit and helps produce smoother bends. This design claims to enhance pulling wire while avoiding the constraints of fixed-angle bends seen in some store-bought options.
IDEASHIP PVC Heat Blanket
The IDEASHIP unit is designed for bending PVC conduit with diameters from 3 1/2″ to 4″. It emphasizes multi-functional bending, enabling bends, offsets, or saddles with a radius around 16 inches. Built with durable silicone heating material and high-quality wiring, it aims for reliable operation in demanding conditions. The product listing also highlights a five-year customer service commitment for replacements due to non-human factors, underscoring a focus on long-term support.
Greenlee 860-1-1/2 PVC Heating Blanket
Greenlee’s 860-1-1/2 is a thermostatically controlled option for 1/2″ to 1-1/2″ PVC conduit. It supports bends, offsets, and saddles with an 8-inch radius. The device wraps around the conduit with a simple hook-and-loop strap, then allows the user to form the bend by hand after heating. The built-in thermostat helps prevent overheating, adding a layer of safety and control during operation.
TEMCo TH4002 PVC Conduit Heat Blanket
The TEMCo TH4002 expands the range to 2″ – 3″ conduit. Like the TH4001, it features a thermostat positioned on the outside of the blanket to promote a snug wrap and smoother bends. The design emphasizes fast heating and flexibility for larger-diameter conduits, enabling efficient bends without compromising temperature control.
Krythonix PVC Heating Blanket For 2″ To 3″
Krythonix offers a 2″ to 3″ PVC heating blanket with adjustable temperature control at 120V and up to 1200W. It supports multiple bending options for PVC pipes in the 2″-3″ range, with a wrap-heat-bend process that simplifies operation. An included hook-and-loop strap helps secure the blanket during heating, enabling a straightforward hand-bend process without specialized tools.
Krythonix PVC Heating Blanket For 1/2″ To 1 1/2″
This Krythonix model covers 1/2″ to 1 1/2″ PVC conduit with adjustable temperature control at 120V. The wrap-heat-bend workflow remains the same, designed for quick bends, offsets, or saddles with minimal tooling. It’s positioned as a versatile option for smaller-diameter conduits and off-site or on-site tasks where portability is important.
Greenlee 860-3 Thermostatically Controlled
Greenlee’s 860-3 variant targets 2″ to 3″ PVC conduit with a 13-inch bend radius. It is designed for straightforward wrapping and hand-forming, with a built-in thermostat to prevent overheating. This option returns to larger-diameter applications, focusing on reliability and consistent heat distribution across bigger pipes.
Buying Guide
Key factors to consider when selecting a PVC blanket heater include diameter range, heating power, and temperature control. Narrower ranges may be adequate for small-diameter conduit, while larger ranges require robust blankets with higher wattage to ensure consistent heat transfer. Temperature control is essential for preventing scorching or softening PVC beyond its tolerance.
- Diameter compatibility: Ensure the blanket supports the pipe or conduit sizes you work with most often, including future projects that may involve different diameters.
- Thermostatic control: A built-in thermostat helps maintain a safe, steady temperature and reduces overheating risk. Some units position the thermostat on the blanket’s exterior for tighter wraps.
- Heating efficiency: Longer blankets or higher wattage can speed up bending, but verify that the unit’s rating aligns with your workflow and electrical setup.
- Durability: Look for silicone heating elements, reinforced textiles, and robust cords to withstand worksite conditions and repeated use.
- Ease of use: Simple wrap-and-secure methods (hook-and-loop straps) reduce setup time and improve safety in tight spaces.
- Warranty and support: Some models offer extended warranties or multi-year service commitments, which can be valuable for ongoing projects.
- Portability and storage: If your work involves field jobs, consider weight, folded size, and how quickly the blanket can be deployed and repacked.
For project planning, compare the five options above not just on price, but on diameter coverage, heat consistency, and ease of use. In environments with limited space or frequent on-site bending, a compact model with reliable thermostat control and quick setup can save time and reduce material waste. Always follow manufacturer guidelines for safe operation and temperature limits to protect PVC integrity and crew safety.
