KOVERTEC HT™ — HIGH-TEMPERATURE PROTECTION
FOR HIGH PRESSURE HOSES
Kovertec HT™:
Typical Cross Section
The safety conditions to which all hydraulic components must conform represent a critical factor when environmental conditions become very tough and adequate protection is vital for component life.
Living up to their mission statement of manufacturing high quality and high technology plastic components, Mazzer has developed a superior product that is becoming a reference within the hydraulic market.
Kovertec HT™ is a plastic protective spiral sleeve that has been designed, tested, and manufactured to offer to the end user a product able to suit almost any field requirements.
Characteristics
Mazzer Kovertec HT™plastic spiral protection is a thermoplastic extruded spiral with a rounded external surface, smoothed edges, and a ribbed internal profile for the protection and bundling of hoses, cables, wires, or similar items. Due to these characteristics, Mazzer Kovertec HT™:
- Is light, yet crush resistant
- Stays in place on the hose without sliding
- Has spirals that easily overlap offering greater protection
- Has an excellent memory
- Springs back when twisted and pulled
