Overview

When sourcing automotive air conditioning hoses, procurement teams often encounter closely related product variants that share a design family but differ in specific dimension sets or designation details. The A20 A/C HOSE(Type C) and the A10 A/C HOSE (Type C) are two such Type C hose lines offered by HEBEI KEMO AUTO PARTS TECHNOLOGY CO., LTD. Both are designed for vehicle air conditioning systems—covering cars, trucks, and other vehicles—and are produced to recognized industry standards. This article compares the two on the criteria most relevant to a sourcing decision: material construction, connection dimensions and wall geometry, pressure ratings, bend radii, permeation values, and refrigerant and application compatibility.

1. Material Construction

Both the A20 A/C HOSE(Type C) and the A10 A/C HOSE (Type C) share an identical multi-layer construction:

The PA/NYLON barrier layer is the critical element responsible for low refrigerant permeability. Both hoses use the same EPDM rubber formulation for tube, friction layer, and outer cover, and both use PET PVA yarn for reinforcement.

Operating Temperature Range: Both hoses are rated for −40 °C to +135 °C (−40 °F to +275 °F).

2. Applicable Standards and Certification

Both products meet the same SAE and Chinese automotive standards and carry the same quality management system certification. Both hoses qualify under SAE J2064 and SAE J3062.

3. Connection Dimensions and Wall Geometry

The two hoses cover an identical set of nominal sizes. The table below lists every documented size for each product using the same units as the source materials.

A20 A/C HOSE(Type C) — Dimensional Specifications

A10 A/C HOSE (Type C) — Dimensional Specifications

The nominal size range and tolerance bands are identical across both hose models. Buyers who need a specific bore size—whether the compact Φ8 (8.2 mm I.D.) or the larger 5/8-inch (16.0 mm I.D.)—will find that same size available in either product line.

4. Pressure Ratings and Minimum Bend Radius

The pressure performance data documented for each product are set out below.

A10 A/C HOSE (Type C)

The working pressure, burst pressure, and minimum bend radius values are identical across all corresponding sizes in both products. Designers routing hoses through tight engine-bay spaces should note that the smaller-bore sizes (5/16, Φ8) share the smallest documented minimum bend radius of 55 mm, while the largest-bore 5/8 and Φ15.2 sizes share the 85 mm minimum.

5. Refrigerant Permeation

Both products have a permeation rate of 1.9 kg/m²/year across every nominal size. This value applies equally to the A20 A/C HOSE(Type C) and the A10 A/C HOSE (Type C), with no size-dependent variation.

6. Refrigerant Compatibility

Both hoses are compatible with R134a, R404a, and R1234yf. The inclusion of R1234yf compatibility is relevant for procurement teams supplying newer vehicle platforms where the lower global-warming-potential refrigerant is mandated.

7. Functional Features

Both products share the same documented functional attributes:

• Low Permeability — PA/NYLON barrier layer limits refrigerant loss.
• Pulse Resistance — Withstands repeated pressure cycling in operational A/C systems.
• Aging Resistance — EPDM outer cover resists degradation over service life.
• Ozone Resistance — EPDM formulation documented as ozone-resistant.
• Shock Resistance — Suitable for vehicle environments subject to mechanical vibration.

8. Packaging Options

Both the A20 A/C HOSE(Type C) and the A10 A/C HOSE (Type C) are offered in the same five packaging formats:

1. Transparent PVC film packing
2. Color woven bag packing (Blue / White / Green / Yellow)
3. Pallet packing
4. Carton packing
5. Spool packing

Spool packing may be preferred for high-volume distributors cutting hose to length, while carton and pallet options suit pre-cut or pre-assembled shipments.

9. Application Scope

Both hoses are intended for use in the air conditioning systems of cars, trucks, and other vehicles. No application restriction distinguishing one product from the other is stated in the available documentation. Procurement teams supplying across passenger car and commercial vehicle markets will find both models applicable.

10. OEM and ODM Services

HEBEI KEMO AUTO PARTS TECHNOLOGY CO., LTD documents OEM and ODM capability for both products, including new product design, development, testing, and the provision of related testing reports as requested by customers.

Summary Comparison Table

Procurement Guidance

On every criterion—material construction, dimensional tolerances, pressure ratings, permeation, refrigerant compatibility, standards compliance, and application scope—the A20 A/C HOSE(Type C) and the A10 A/C HOSE (Type C) produce equivalent results.

For distributors or OEM buyers who need to select between these two Type C hose lines, the recommended approach is to:

1. Confirm the required nominal bore size — both products cover the same nine sizes from Φ8 (8.2 mm I.D.) to 5/8 inch (16.0 mm I.D.).
2. Verify the applicable refrigerant — both are compatible with R134a, R404a, and R1234yf.
3. Request KEMO's testing reports — HEBEI KEMO AUTO PARTS TECHNOLOGY CO., LTD offers product-specific testing reports through its OEM/ODM service, which may reveal additional differentiation relevant to a specific vehicle platform or assembly requirement.
4. Specify packaging format — both hose lines support the same five packaging options; spool packing suits high-volume cutting operations.
