Product Description

SAE J20 R3 EPDM Coolant System Heater Hose For Normal Service

A low permeation fuel hose with a PA (polyamide) lining is a specialized type of fuel hose designed to reduce or prevent the permeation of fuel vapors through the hose material. Permeation refers to the process by which molecules of fuel, such as gasoline or diesel, penetrate and pass through the walls of the hose, leading to the loss of fuel and potential safety hazards.

The polyamide lining in a low permeation fuel hose acts as a barrier to prevent fuel vapors from escaping through the hose material. Polyamide is a type of synthetic polymer known for its excellent resistance to fuels, oils, and chemicals, making it an ideal material for lining fuel hoses. The PA lining helps to maintain the integrity of the hose and prevent fuel leakage or vapor emissions.

Low permeation fuel hoses with a PA lining are commonly used in automotive and marine applications where fuel system efficiency and emissions control are critical. These hoses are designed to meet strict environmental regulations and emission standards by reducing evaporative emissions from the fuel system.

In addition to the polyamide lining, low-permeation fuel hoses may also feature additional layers of reinforcement and protection to withstand the pressures and forces involved in fuel delivery systems. These hoses are typically constructed with a combination of synthetic rubber compounds, textile or wire reinforcement, and outer covers for durability, flexibility, and resistance to abrasion and environmental factors. Low permeation fuel hoses with a PA lining are available in various sizes, lengths, and pressure ratings to meet the requirements of different fuel systems and applications. Proper selection, installation, and maintenance of these hoses are essential to ensure fuel system integrity, prevent fuel vapor emissions, and comply with regulatory requirements.

Our Advantages

HEAT AND WEATHER RESISTANCE
EPDM hoses are designed to withstand high temperatures and are resistant to weathering, making them ideal for use in coolant systems where hot temperatures are common.

FLEXIBILITY
EPDM hoses are flexible and can easily be bent and routed in the engine compartment, allowing for easier installation and routing compared to rigid hoses.

DURABILITY
EPDM coolant system heater hoses are durable and long-lasting, able to withstand the harsh conditions of the engine compartment, including exposure to heat, coolant, and other automotive fluids.

RESISTANCE TO CHEMICALS
EPDM hoses are resistant to a variety of automotive fluids, including coolant, making them suitable for use in coolant systems without the risk of degradation or corrosion.

COST-EFFECTIVENESS
EPDM hoses are generally more cost-effective than other types of hoses, providing a reliable and budget-friendly solution for coolant system applications.
