KOVERTEC PSA™ — GLOBAL PROTECTION
FOR HIGH PRESSURE HOSES
Kovertec PSA™:
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 PSA™ 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 PSA™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 PSA™:
- 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

The information given in this chart should be used only as a guide. Our laboratory testing cannot possibly duplicate all combinations of environmental factors or conditions present during applied service. We also strongly recommend that you refer to the raw material manufacturer's or supplier's Web site or other reference materials for more information.
Very Good Chemical Compatibility:
| Gasoline | | Ionic Metallic Solutions | | Mineral Oil |
| | Oil | | Superior Alcohols | | Vegetable Oil |
| |
Poor Chemical Compatibility:
| | Ethyl Acetate | | Methyl Acetate |
|
Chemical Compatibility Notes:
| 1) [Water]: Product becomes more flexible after a prolonged exposure to moisture or water. | | 2) [Strong Acids]: Strong acids such as HCl may have some corrosive action. | | 3) [Strong Bases]: Strong bases such as NaOH may have some corrosive action. | | 4) [Inferior Alcohols]: Inferior alcohols such as ethylic and buthylic alcohol may, after a prolonged immersion, expand the product but they do not act as a solvent. |
