Start with the refrigerant and temperature range

The service medium and temperature range should be fixed before you compare an AC hose manufacturer. Our Formed AC Hose is intended for automotive or domestic air-conditioning systems and is listed for R134a, R404a and R12 refrigerants. Its working temperature range is -40°F to 284°F (-40°C to +140°C).

That range gives you a first screen for vehicle and equipment applications that experience cold starts, hot engine-bay conditions or both. Record the refrigerant and expected temperature range with the quotation request. Match the hose to the actual system medium and routing conditions, not to the outside diameter alone.

Match the hose size to the connection layout

Four standard sizes are available:

Use the inner diameter to match the connection and flow path, then check the outer diameter against clamps, brackets, channels and nearby components. Wall thickness affects the space occupied by the assembled hose, so include it in the routing drawing.

A practical review starts with the mating connection sizes and ends with the complete path through the vehicle or equipment. Measure clearance around bends and mounting points, then compare those measurements with the hose's outside diameter. The product has a tighter bend radius for compact layouts, but your assembly drawing should control the final fit.

Check pressure against the system requirement

The maximum working pressure is 3.5 MPa, or 500 psi, and the maximum burst pressure is 22.0 MPa, or 3,000 psi. These values set the pressure boundary for comparing the hose with your air-conditioning circuit.

Select Formed AC Hose when the required working pressure stays within 3.5 MPa and the assembly fits one of the four size options. The burst value is a pressure-margin reference, not a target operating pressure. Send the normal working pressure and any pressure-pulse conditions with your inquiry so we can review the application against the selected size and construction.

Pulse resistance, aging resistance, ozone resistance and shock resistance suit assemblies exposed to vibration and changing under-hood conditions. These properties do not replace a check of the hose path, connection method and pressure duty of your system.

Review the layered construction

The construction is arranged by function. The tube uses EPM, CSM and IIR. A PA/Nylon barrier forms the barrier layer, and PET/PVA provides reinforcement. Include the tube, barrier and reinforcement materials with the selected size in your procurement specification.

This structure matters in a formed route where refrigerant retention, reinforcement and contact with surrounding parts all affect the selection. The barrier layer supports low permeability, while the reinforcement and outer layers handle pressure, movement and external exposure.

Which buyer situation fits this hose?

Formed AC Hose fits automotive or domestic air-conditioning assemblies that use R134a, R404a or R12, require one of the four listed nominal sizes, and operate between -40°F and 284°F. It suits compact routing where a tighter bend radius helps the hose pass through a crowded layout.

Picture a vehicle installation with the hose running past brackets and other components. Check the outside diameter, wall thickness and bend path together before ordering. For a stationary domestic air-conditioning assembly, start with the refrigerant, connection size and temperature duty, then confirm that working pressure remains within 3.5 MPa.

The product fits requests within these refrigerant, size, temperature and pressure boundaries. Send the complete operating specification before selecting a hose for another service condition.

Questions to settle before ordering

Prepare the specification for a quotation

Formed AC Hose suits air-conditioning assemblies within its refrigerant list, temperature range, pressure limits and four size choices. Send the refrigerant, working pressure, temperature range, connection sizes, routing drawing, selected layer construction and required quantity with your quotation request.
