45° and 90° Hose Bends

UNIVERSAL HOSE BENDS

Mackay Automotive offers premium 45° and 90° Universal Hose Bends, designed for a variety of applications in the automotive and industrial sectors. Available in two specifications, these hoses provide reliable solutions for both water and fuel & oil systems, ensuring durability and long-lasting performance.

45° & 90° UNIVERSAL HOSE BENDS – WATER

Mackay 45° & 90° Universal Hose Bends for water are perfect for plain water and automotive coolant applications. These hoses are manufactured using electrochemical degradation (ECD) resistant EPDM rubber, with a lock-stitch knitted Aramid fibre reinforcement and an EPDM rubber cover. This construction ensures superior heat and ozone resistance, providing a long service life in demanding conditions.

Applications: Water coolant, plain water transfer.
Material: EPDM rubber, Aramid fibre reinforcement.
Resistance: Heat, ozone, and electrochemical degradation.

45° & 90° UNIVERSAL HOSE BENDS – FUEL & OIL
The 45° & 90° moulded Fuel & Oil hoses use two constructions depending on size.
Sizes 8mm to 19mm ID are suitable for low pressure fuel applications and are manufactured using a Nitrile (NBR) rubber tube, lock-stitch knitted Polyester fibre reinforcement, with an oil resistant Hypalon® (CSM) rubber outer cover for maximum heat and ozone protection.

The 45° & 90° Moulded Fuel & Oil hoses use two constructions depending on size.

Sizes 8mm to 19mm ID are suitable for low-pressure fuel applications. These hoses are manufactured using a Nitrile (NBR) rubber tube with lock-stitch knitted Aramid fibre reinforcement, with an oil-resistant Hypalon® (CSM) rubber outer cover. The design ensures maximum protection against heat and ozone protection, making them ideal for automotive fuel systems.

Applications: Low-pressure fuel transfer, oil systems.
Material: Nitrile rubber tube, Aramid fibre reinforcement, Hypalon® outer cover.
Resistance: Heat, ozone, and oil.

Both the 45° & 90° Universal Hose Bends for water and fuel/oil are engineered for ease of installation, superior durability, and exceptional resistance to harsh environments, making them the go-to choice for automotive systems.
