Description
Material of the Pride Vacuum Hose
(Raw Materials Used in Manufacturing the Pride Vacuum Hose)
The Pride vacuum hose is produced in two material classes: EPDM (high-quality) and SBR (standard quality).
It is a double-layered rubber hose, reinforced with polyester yarn, which increases its strength and performance under vacuum pressure conditions.
Service Life of the Pride Vacuum Hose
The lifespan of the Pride vacuum hose varies based on the material used:
-
When manufactured with high-quality EPDM, the hose typically lasts about 4 years.
-
When made from standard SBR, the hose’s lifespan is generally 6 months to 1 year.
Signs of Wear in the Pride Vacuum Hose
(How to Identify a Faulty Pride Vacuum Hose)
Some clear signs of hose damage include:
-
Surface cracking:
Visible cracks on the outer layer are an early indication of aging. The deeper and more frequent the cracks, the more worn-out and fragile the hose has become. -
Bulging:
Uneven swelling on the hose surface shows internal pressure issues and structural breakdown. -
Peeling or “double-layering”:
Known as “two-layering,” this happens when the hose begins to separate into thin surface layers. It indicates poor-quality material or extensive wear.
In any of these conditions, it’s strongly recommended to replace the hose promptly.
Consequences of a Faulty Pride Vacuum Hose
(Impact of Hose Failure on Vehicle Performance)
The most notable consequence of vacuum hose failure is radiator coolant loss, which can lead to:
-
Overheating of electrical wires and harnesses
-
Potential head gasket damage due to low coolant levels
-
Hot radiator fluid leaking into the vehicle cabin
How to Tell a Good Hose from a Bad One
(Identifying High-Quality vs. Low-Quality Pride Vacuum Hoses)
Key differences include:
-
Surface finish:
EPDM-made hoses usually have a smooth, glossy finish, while SBR-based hoses appear dull and lack luster. -
Surface defects:
A high-quality hose is free of blisters, pitting, and peeling (double layering). -
Smell test:
If you can’t inspect the hose under proper lighting, smell it. Hoses made from premium EPDM typically emit a sweet rubber scent, whereas low-grade ones may not.
