How is SAE J2064 Type C Manufactured? Process Flow & Material Selection

Material Selection Step 1: EPDM (ethylene propylene diene monomer), Polyamide (PA), or CSM (chlorosulfonated polyethylene) resins are chosen for the inner tube for their chemical resistance and durability.
Inner Tube Extrusion Step 2: High-precision extruders form the inner wall to tight tolerances (ID deviation ≤0.05mm, per ISO 3302-1).
Braiding Reinforcement Step 3: Automated CNC braiders apply high-tensile polyester or aramid fibers.
Outer Cover Extrusion Step 4: Outer sheath of CR/EPDM is extruded for protection against weather, oil, abrasion.
Vulcanization & Curing Step 5: Continuous steam curing (180–210°C) ensures optimal elasticity and mechanical bonding.
Quality Inspection Step 6: Each batch is 100% tested (burst, leakage, permeation) to SAE J2064 and ISO 9001:2015 standards.
Cutting & Packaging Step 7: Computer-guided cutting, custom length/kitting, with labeling documentation/traceability.

Technical FAQ: SAE J2064 Type C & E TYPE Factory A/C Hose

Q1: What are the advantages of using PA+EPDM for the inner tube?
PA (polyamide) offers strong chemical compatibility with R134a, R1234yf, and PAG/POE oils, while EPDM enhances ozone/aging resistance. This combo ensures sae j2064 type c hoses deliver superior permeation resistance and longevity, crucial for modern automotive AC lines.
Q2: Which permeation rate standards must be met?
sae j2064 type c hoses must achieve permeation rates ≤0.05kg/m²/yr using SAE J2064 and ISO 1307 test methods, minimizing refrigerant loss and improving eco-sustainability.
Q3: How should these hoses be installed (installation standards)?
Per SAE J2064 and SAE J639, ensure routing avoids sharp bends (bend radius ≥4× hose OD), connectors are torque-set per ASTM F876, and clamp supports are used every 60–90cm.
Q4: What is the typical burst pressure and why is it important?
sae j2064 type c hoses should withstand burst pressure ≥13.0 MPa, providing significant margin above maximum working pressures (35 bar/3.5 MPa) to ensure operational safety across temp fluctuations.
Q5: Are these hoses compatible with HFO and legacy refrigerants?
Yes. Our sae j2064 type c and sae j2064 type e products are compatible with HFO-1234yf, HFC-134a, CFC-12, and new HFC/HFO blends, as demonstrated in compatibility tests (ISO 7302).
Q6: What classifies a hose as "Type C Class II"?
"Class II" in SAE J2064 refers to hoses with even lower permeation thresholds and extended temperature/pressure resilience, typically used in hybrid/electric commercial vehicles.
Q7: What documentation is supplied with each order?
Customers receive a product COA, batch test record, installation guide, and conformity certificate matching sae j2064 pdf documentation.
