Product Name
Leister 140.161 1.1-inch (28mm) Silicone Pressure Roller
Brief Description
The Leister 140.161 is a high-quality, ergonomically designed hand pressure roller featuring a 1.1-inch (28mm) silicone roller with ball bearings and a durable wooden handle. It is an essential accessory for hot air welding tools, specifically engineered to apply uniform and consistent pressure during plastic welding and various bonding applications, ensuring a smooth, professional finish.
Popular Applications & Uses
- Plastic welding projects, such as repairing tarpaulin and smoothing PVC banners.- Welding of roofing membranes and geomembranes in civil engineering.- Applications involving technical textiles and industrial fabrics, including commercial vehicle side curtains, boat covers, and marquee repair.- Laminating processes.- Smoothing out ridges and removing air bubbles in various materials.- Ensuring thorough adhesion during the installation of flooring, roofing, decals, or wallpapers.- Ideal for intricate seam welding applications due to its smaller size.
Industries that Commonly Use It
- Construction/ Building Services (for roofing, flooring, and general building applications)- Tarp, Fabric, Awning Manufacturing (for welding and repairing tarpaulins, banners, and covers)- Plastic Fabrication (for various plastic welding and bonding tasks)- Flooring Installer or Manufacturer (for seamless flooring installation)- Sign & Display (for smoothing and sealing PVC banners and other display materials)- Transportation/ Specialty Vehicle (for manufacturing and repairing commercial vehicle side curtains and boat covers)- General Manufacturing (for broad applications requiring precise pressure application in plastic processing)- Cladding (for sealing and finishing waterproof membranes)
Special and Unique Features
- Ergonomic design with a wooden handle provides a comfortable grip and reduces operator exertion during prolonged use.- Features a silicone roller with smooth-action ball bearings, ensuring stable and flexible operation.- The silicone material offers high temperature resistance, up to 260 degrees Celsius, and non-stick properties.- Built for durability and long-lasting performance, reflecting Leister's quality standards.- Its bow shape is suitable for both left and right-handed operators, allowing for higher pressure application without strain.- Engineered to require less grip pressure from the operator to achieve effective sealing.- The compact 28mm size is particularly suited for intricate and detailed seam welding applications.

Known backups / known substitutes
- Leister 140.160 1.6-inch (40mm) Silicone Pressure Roller, or other Leister silicone pressure rollers of varying widths (e.g., 80mm).- Leister brass pressure rollers (e.g., 6mm, 7mm, 106.972), often used for detail work.- Leister PTFE (Polytetrafluoroethylene) pressure rollers (e.g., 8mm, 28mm), known for temperature resistance and preventing membrane damage.- Generic silicone pressure rollers from other manufacturers.- Replacement silicone sleeves (e.g., Leister 140.598 for the 28mm roller) can extend the life of the existing roller.
Comparison Note
Silicone pressure rollers, like the Leister 140.161, are highly valued for their non-stick properties and excellent high-temperature resistance, which are crucial for evenly spreading materials and effectively eliminating air bubbles during welding and bonding. In contrast, PTFE rollers also offer good temperature resistance and are beneficial for detailed work, as they help prevent damage to delicate membranes. Brass rollers, while effective for certain applications, can heat up more easily and potentially cause harm or wrinkles to sensitive membranes if not used carefully.
