40mm Silicone Seam Roller for Plastic Welding

40mm Silicone Seam Roller for Accurate Plastic Welding

This 40mm silicone handwheel seam roller is designed for controlled, consistent pressure during hot air plastic welding. Built for demanding jobsite use, it delivers reliable performance when working with PVC, TPO, EPDM and other thermoplastic membranes.

The roller features a 40mm-wide silicone wheel with a smooth, wear‑resistant surface that withstands temperatures up to 260°C. Silicone construction helps prevent sticking and ensures even pressure along the weld seam. A solid wood handle provides a comfortable, secure grip, while the ergonomic shape supports precise control during detailed work and long welding sessions.

Equipped with a two‑way bearing design, the roller moves smoothly and flexibly in both directions, helping you maintain a consistent travel speed and uniform weld appearance. The detachable structure allows for straightforward bearing replacement and maintenance, extending tool life. This roller is suitable for high‑temperature welding of PVC waterproof membranes, tarpaulin membranes, and other plastic sheet materials, and can also be used for pressing wallpaper seams, corner details, and vehicle films where controlled pressure is required.

Why It's a Smart Choice

• High heat resistance - Silicone wheel rated up to 260°C supports demanding hot air welding applications.
• Stable, smooth operation - Two‑way bearings provide low‑friction rolling for consistent weld speed and clean seams.
• Comfortable, serviceable design - Solid wood handle and detachable structure enable precise handling and easy maintenance.
