Seam Roller 260 32mm Diameter 40mm Width Silicone Seam Roller with Test Probe for Welding f26 1High Temperature Resistance: The surface of the pressure wheel can withstand high temperatures up to 260, and is made of high temperature resistant silicone material, finely processed. Matte frosted surface, wear resistant, smooth, and more resilient. Used for high temperature welding of PVC waterproofing membranes and tarpaulin membranes. 2With A Test Probe: The seam roller can effectively detect the welding joint of TPO coil material, inspect all welding seams to ensure that there is no missing welding, and ensure the reliability of welding seam quality. 3Convenient Operation: Adopting a 1 wheel 2 bearing design, the seam roller with probe is stable and does not deviate, making the operation more flexible and preventing jamming during the construction process, effectively improving welding speed and construction quality. The design of high speed steel bearings is more stable, with a sturdy and detachable structure, making it easy to replace and operate more freely. 4Handle Design: The handle is made of premium wood, which is wear resistant and ergonomically designed. It is not easy to wear out, has a comfortable feel, and is closer to your hand. 5Wide Application: Mainly used for welding membrane and sheet materials and checking the virtual welding and missed welding of waterproof layer welds, such as PVC, TPO coil welding joints, EPDM adhesive joints, etc.
