Value Collection 6440x2 Coolant Hose Adapter 3/4 in 2-pack

Product Description

The VALUE COLLECTION 6440x2 is a coolant hose adapter designed to connect coolant hoses in engine cooling and fluid transfer systems. Sold as a pack of two, this non-threaded adapter features a 3/4 inch inside diameter and is rated for a maximum working pressure of 20.30 psi. It serves as a connector socket between coolant hose segments or between a hose and a barbed fitting, making it a practical replacement or supplemental component for cooling system service and repair work. Installation is typically performed by automotive or HVAC technicians handling fluid-handling assemblies.

This adapter is suited for low-pressure coolant circuits where a 3/4 inch inside diameter hose connection is required. Typical applications include radiator hose assemblies, heater core lines, and similar closed-loop fluid transfer plumbing where non-threaded push-on or slip-fit connections are used. The 20.30 psi pressure rating keeps it within the normal operating range of most light-duty engine cooling systems. Each pack contains two adapters, supporting back-to-back repairs or stocking of a spare.

Key Features

• 3/4 inch inside diameter fits standard coolant hose sizes
• Rated to 20.30 psi maximum pressure for low-pressure cooling circuits
• Non-threaded slip-fit design for straightforward hose-to-hose connection
• Sold in a pack of two for multi-point repairs or spare inventory
• Compact form factor suited for tight engine bay routing

Compatibility

Designed as an OEM-style replacement adapter for cooling and fluid transfer systems requiring a non-threaded 3/4 inch inside diameter hose connection.

Installation Notes

Drain and depressurize the cooling system fully before removing any hose or fitting. Allow the engine to cool completely to avoid scalding from residual coolant. Secure hose clamps at the appropriate positions over each end of the adapter to prevent leaks. Refill and bleed the cooling system according to the equipment manufacturer's procedure after installation.
