TEMCo TH4002 PVC Conduit Heat Blanket Bender 2-3″

Check Price on Amazon

This TEMCo model targets electricians and installers who need controlled heating for PVC conduit bending. The design is patented to wrap tighter to conduit, which improves heat transfer and can produce smoother bends. The thermostat is mounted on the outside of the blanket, helping the wrap remain snug while allowing temperature control.

• Patented Wrap Design — Tight contact with pipe for efficient heating and faster bending.
• External Thermostat — Thermostat placement minimizes internal bulk and helps maintain closeness to conduit.
• Versatile Bending — Blanket allows making any angle bend rather than fixed-angle fittings.

TEMCo TH4001 PVC Conduit Heat Blanket Bender 1/2″ – 1 1/2″

Designed for smaller conduit sizes, the TEMCo TH4001 features an extended blanket length to enable wider-radius bends than many competing benders. The external thermostat location is consistent with TEMCo’s design intent to keep the blanket tight to the conduit for uniform heating.

• Longer Blanket For Wider Bends — Prioritizes radius flexibility for easier wire pulling post-bend.
• External Thermostat — Facilitates tighter wrap and consistent heat application.
• Angle Flexibility — Not limited to specific preset angles; suitable for custom bends.

Rama Corporation PVC Heating Blanket 3-1/2″ To 4″ PVC Conduit

The Rama blanket is marketed for even heating across the blanket surface and includes built-in stiffeners to deliver a snug fit around conduit. It emphasizes a thermostatically controlled system with adjustable temperatures up to 300°F (149°C), making it suitable for controlled heating tasks such as bending PVC and thawing frozen lines.

• Even Heating — Built-in stiffeners help maintain contact and distribute heat uniformly.
• Durable Construction — Reinforced material and extra-long cord for jobsite use.
• High Temperature Range — Thermostat adjustable up to ~300°F for a range of heating tasks.

The codree two-pack focuses on freeze protection for exposed water pipes. The wrap uses an aluminum foil exterior with waterproof flannelette interior layers and sewn-in heating wire. The set includes two blankets, each with a long power cord, and a built-in temperature control rated up to 60°C (140°F).

• Two-Pack Convenience — Useful for protecting multiple short pipe runs or successive sections.
• Aluminum Foil Exterior — Aims to improve thermal conduction and reflectivity.
• Temperature Controlled — Designed to limit overheating with a 60°C max setpoint.

3 Ft YeloDeer 110V Stickable Waterproof Pipe Heat Tape Blanket

YeloDeer’s wrap is presented as a stickable, waterproof heating blanket sized for standard outdoor hydrant and RV pipes. It features an aluminum foil lining with a waterproof flannelette exterior, sewn heating wires, and a 6-foot power cord. The wrap’s heating upper limit is 140°F (60°C), and its design emphasizes energy efficiency and insulation.

• Stickable & Waterproof — Adhesive-friendly backing and weather-resistant exterior for outdoor use.
• Sewn Heating Wires — Integrates heating elements within the fabric for even warmth.
• Energy-Saving Claim — Upper temperature limit intended to prevent overheating and conserve energy.

Buying Guide: How To Choose The Right Pipe Heater Blanket

Selecting the correct pipe heater blanket depends on the application: conduit bending, PVC forming, thawing, or freeze protection for water lines. Below are key considerations and comparison perspectives to guide the choice.

1. Application And Heating Requirements

Define the primary use before choosing a blanket. For PVC conduit bending, look for blankets with thermostatic control and tight wrap design to deliver concentrated, uniform heat. For freeze protection, pick wraps rated for continuous outdoor use with waterproof exteriors and controls that prevent overheating.

2. Temperature Range And Control

Temperature capability determines suitability. PVC forming often requires higher, controlled temperatures; some heating blankets list setpoints up to 300°F. For freeze protection, a lower maximum (around 140°F / 60°C) is common and safer for continuous operation. Ensure the blanket includes a reliable thermostat or temperature limiter.

3. Fit And Contact With The Pipe

Efficient heat transfer needs snug contact. Models with built-in stiffeners or patented wrap designs help maintain uniform contact for bending or thawing. For irregular shapes or larger diameters, confirm the blanket’s stated pipe diameter range and whether the wrap can be secured tightly.

4. Power Cord Length And Voltage

Check cord length against installation needs. Longer cords and standard 110–120V plugs are practical for outdoors or jobsite use. Ensure the unit matches local voltage standards and that extension use follows safety recommendations.

5. Durability And Construction

Outdoor freeze protection requires weather-resistant exteriors such as aluminum foil with waterproof flannelette or oxford fabric. For high-heat applications like soldering proximity, pick materials rated for higher temperatures or use heat shields to protect surroundings.

6. Safety Features

Look for built-in thermostats, overheat protection, and temperature-limited designs. For continuous outdoor use, waterproofing of electrical connections and proper grounding are important. Follow manufacturer instructions for secure fastening and avoidance of sharp edges or abrasion.

7. Size, Coverage, And Multipack Options

Measure the pipe circumference and length to choose an appropriate blanket size. Multipacks (2 in a set) are useful when protecting multiple short sections or wrapping long runs in staggered segments. Ensure overlapping areas do not create excessive local heat.

8. Specialized versus General-Purpose Designs

Specialized conduit bender blankets focus on concentrated heating and bending flexibility, while general-purpose pipe wraps prioritize freeze protection and weather resistance. Choose the design that aligns with your primary tasks to get the best performance.

9. Ease Of Use And Installation

Features like adhesive backing, Velcro closures, or shape-adapted cutouts affect installation speed. For frequent use on different pipes, a design with an external thermostat and simple wrap/secure mechanisms can save time.

10. Compliance And Best Practices

Follow local electrical codes for outdoor electrical devices. Avoid running heating blankets over damaged insulation. Use Ground-Fault Circuit Interrupter (GFCI) protection for outdoor or wet-area installations, and follow manufacturer safety instructions for continuous operation.

Comparison Perspectives Summary

• Conduit Bending — Prioritize external thermostat, tight wrap, and high temperature range (TEMCo, Rama).
• Freeze Protection — Prioritize waterproof exterior, moderate temp limit, and continuous-safe controls (codree, YeloDeer, Mofuiry-style wraps).
• Durability — Metal-reflective aluminum exterior and reinforced stitching extend life in cold, wet conditions.
• Multiple Sections — Multipacks or longer blankets reduce seam points and simplify protection for longer pipe runs.
