Guarding Your System: Understanding Parker Hannifin's Robust Hose Covers
A robust hose cover is a key factor in preserving the integrity of your hydraulic systems. It’s the first and often only line of defense protecting your hose in harsh operating environments. At Triad Technologies, we know that choosing the right hose cover can drastically extend the life of your hose assembly, reduce costly downtime, and enhance safety. That’s why we’re proud to carry Parker Hannifin ToughCover (TC), SuperTough (ST), Critical Protection (CP), and the related Tough Jacket (TJ) solutions!
Hose covers are a critical component in protecting your hose's reinforcement layers from external damage. Some key benefits of choosing a hose with a robust cover include:
Abrasion Resistance: Constant rubbing against machinery, debris, or other hoses is the leading cause of hose failure. A robust cover prevents this wear from reaching the core.
Environmental Protection: Covers shield the hose from ozone, UV rays, moisture, and chemical exposure, which can degrade rubber compounds over time.
Impact Protection: In rugged environments like mining or forestry, falling objects or heavy impacts can damage the hose. Advanced covers offer a crucial layer of resistance.
Reduced Downtime & Maintenance Costs: A durable cover ensures your hose lasts longer, meaning fewer replacements and less unplanned downtime.
Enhanced Safety: By preventing premature failure, robust covers help mitigate the risk of fluid injection injuries and environmental spills.
Choosing a hose with a reliable cover can eliminate the need for expensive, bulky, or labor-intensive guards or sleeving. Parker Hannifin offers a tiered system of abrasion-resistant hose covers designed to meet the demands of various operating conditions. Click through the tabs below to explore the features and benefits of Parker’s ToughCover (TC), SuperTough (ST), Critical Protection (CP), and Tough Jacket (TJ) variants.
ToughCover (TC)
This is Parker’s entry-level abrasion-resistant cover, a significant upgrade from their standard cover. It's a synthetic rubber formulation suitable for general heavy-duty hose applications.
| Features | Details |
|

Synthetic rubber (neoprene/nitrile blends) |
|
Abrasion Resistance |
Good - suited for moderate to heavy-duty industrial use; 80 times more resistant than a standard rubber cover, but not ideal for severe abrasion applications |
|
Chemical Resistance |
Resistant to oils and fuels |
|
Temperature Range |
Varies by hose series |
|
Flexibility |
Balanced toughness and flexibility for easy installation |
|
UV & Ozone Resistance |
Good - suited for outdoor environments |
|
Cut & Puncture Resistance |
Moderate - not for extreme cut/gouge protection |
|
Weight |
Moderate - heavier than thermoplastics, but lighter than metalic covers |
|
Typical Applications |
Hydraulic hoses, industrial applications, and construction equipment |
|
Key Benefits |
Durable, versatile, and protects against mechanical and environmental damage |
|
Limitations |
Not ideal for extreme abrasion resistance |
|

GlobalCore Series with “TC” in the name, such as 487TC and 787TC |
SuperTough (ST)
This cover offers substantially more protection than TC, making it ideal for the truly abusive conditions found in many mobile and fixed-plant applications. It is engineered to withstand more intense, constant friction.
| Features | Details |
|
Material Type |
Thick, rugged, synthetic rubber |
|
Abrasion Resistance |
Superior - thicker and more resistant than ToughCover; 450 times more resistant than a standard rubber cover |
|
Chemical Resistance |
Good resistance to oils and fuels |
|
Temperature Range |
Varies by hose series |
|
Flexibility |
Less flexible due to thicker cover |
|
UV & Ozone Resistance |
Excellent - suited for demanding outdoor use |
|
Cut & Puncture Resistance |
Enhanced protection compared to ToughCover |
|
Weight |
Moderate - heavier than ToughCover due to increased thickness |
|
Typical Applications |
Heavy-duty applications like mining, forestry, and rugged mobile equipment where severe abrasion is expected |
|
Key Benefits |
Protective even in extreme conditions, resulting in exceptional wear life and reduced downtime |
|
Limitations |
Not ideal for impact resistance |
|

GlobalCore Series with “ST” in the name, such as 487ST and 787ST |
Critical Protection (CP)
This is Parker's innovation that adds impact resistance to a high level of abrasion resistance (like ST). The Critical Protection cover uses a patent-pending technology to better protect the hose from external impact damage caused by objects falling or striking the line, preventing the cover from being stripped off and exposing the inner layers.
| Features | Details |
|
Material Type |
Thick, rugged, synthetic rubber |
|
Abrasion Resistance |
Superior - thicker and more resistant than ToughCover; comparable to SuperTough |
|
Chemical Resistance |
Good resistance to oils and fuels |
|
Temperature Range |
Varies by hose series |
|
Flexibility |
Less flexible due to a thicker cover |
|
UV & Ozone Resistance |
Excellent - suited for demanding outdoor use |
|
Cut & Puncture Resistance |
Enhanced protection compared to ToughCover, increased impact damage protection |
|
Weight |
Heavier than ToughCover due to increased thickness |
|
Typical Applications |
The most demanding, harsh environments, especially where falling debris, impacts, and severe rubbing are issues (e.g., underground mining, logging) |
|
Key Benefits |
Protective even in extreme conditions, resulting in exceptional wear life and reduced downtime |
|
Limitations |
Higher initial investment |

Tough Jacket (TJ)
Though Tough Jacket boasts the highest abrasion resistance figure of these cover options (up to 650x), its use is often reserved for applications where low length change under pressure is critical, such as cranes or lift equipment. The consistent length of this hose prevents it from pulling out of cable tracks or over-the-sheave assemblies.
| Features | Details |
|
Material Type |
Thermoplastic polyurethane |
|
Abrasion Resistance |
Very good - up to 650 times more resistant than a standard rubber cover |
|
Chemical Resistance |
Resistant to oils and fuels |
|
Temperature Range |
Varies by hose series |
|
Flexibility |
Very flexible - easy to handle and install |
|
UV & Ozone Resistance |
Excellent - suited for demanding outdoor use |
|
Cut & Puncture Resistance |
Good cut resistance, though less than heavy-duty rubber hoses |
|
Weight |
Lightweight compared to rubber or metal covers |
|
Typical Applications |
Pneumatic hoses, air lines, water lines, and general industrial use |
