The hose is used in the air conditioning systems of cars, trucks, and other vehicles. Listed refrigerants are R134a, R404a, and R12.

Its four-layer construction consists of a PA/nylon barrier, an EPDM, CSM, or IIR friction layer, PET or PVA reinforcement, and an EPDM cover. The listed product characteristics include low permeability, pulse resistance, aging resistance, ozone resistance, and shock resistance.

For a replacement line, match the refrigerant and vehicle application first. For a production assembly, provide the routing layout and connection requirements so the hose size can be checked against the installation.

The listed size options are Φ8, Φ11.2, Φ13, Φ15.2, 3/4 inch, 7/8 inch, and 1-1/8 inch. Inside diameters range from 8.2 mm to 28.5 mm, while outside diameters range from 15.2 mm to 41.0 mm, depending on the selected size.

The size table gives the following inside diameter and outside diameter pairs: Φ8 is 8.2 mm and 15.2 mm; Φ11.2 is 11.4 mm and 18.4 mm; Φ13 is 12.8 mm and 20.8 mm; Φ15.2 is 15.4 mm and 22.8 mm; 3/4 inch is 19.0 mm and 28.6 mm; 7/8 inch is 22.0 mm and 32.0 mm; and 1-1/8 inch is 28.5 mm and 41.0 mm.

Measure the available space around the line and compare it with the selected hose's outside diameter before ordering. Send the required quantity, hose length, size, and connection details to air conditioning hose suppliers for a configuration review.

Maximum working pressure is listed as 3.5 MPa, or 508 psi, for the listed sizes. Minimum burst pressure varies by size: 21 MPa for Φ8 and Φ11.2, 22 MPa for Φ13, and 18 MPa for Φ15.2, 3/4 inch, 7/8 inch, and 1-1/8 inch. The corresponding listed burst pressures are 3045 psi, 3190 psi, and 2610 psi.

Minimum bend radius is 55 mm for Φ8, 65 mm for Φ11.2, 70 mm for Φ13, and 85 mm for Φ15.2, 3/4 inch, 7/8 inch, and 1-1/8 inch. In a vehicle routing check, measure the tightest bend and compare it with the selected size's minimum bend radius.

The listed temperature range is -40°C to +135°C, or -40°F to +275°F. Permeation is listed as 1.6 kg/m²/year for the listed sizes.

Use the temperature range and permeation figure when preparing the technical requirements for a vehicle air conditioning line. Include the expected operating conditions with the size, refrigerant, hose length, and connection layout when asking suppliers to review the application.

The product listing identifies SAE J2064, SAE J3062, and QC/T664 under Standard. KEMO can provide OEM and ODM services, including new product design, development, testing, and related testing reports at the customer's request.

For a quotation or technical review, send the application, refrigerant, selected or required size, quantity, hose length, connection requirements, and report format. Those details allow the supplier to address the intended hose configuration and requested testing support.
