A20 A/C HOSE (Type C): Notes From The Line Between Compressor and Evaporator

The Ac Hose From Compressor To Evaporator is one of those parts nobody notices until summer heat hits and cabin air turns lukewarm. I’ve toured plants from Detroit to Hebei, and—honestly—this is the quiet workhorse. KEMO’s A20 A/C HOSE (Type C), built in Niu Jiazhai Industrial Area, Changzhuang Town, Wei County, Hebei, surprised me with its pragmatic engineering and steady, no-drama performance.

What’s inside matters

Under the black EPDM cover is a thoughtful stack: EPDM tube, PA/NYLON barrier for low permeability, PET/PVA reinforcement for strength, and an EPDM friction layer. That balance keeps refrigerant in and moisture out—vital when your Ac Hose From Compressor To Evaporator faces pulsing pressures and engine-bay heat. It’s built to SAE J2064 and J3062, with QC/T 664 in the background, and the factory is ISO/TS 16949:2009 certified. Formal enough, but not fussy.

Parameter A20 Type C Spec Notes
Temperature Range -40°C to +135°C (-40°F to +275°F) Under-hood spikes may momentarily exceed; real-world use may vary
Tube / Barrier EPDM / PA-NYLON Low refrigerant permeation
Reinforcement PET, PVA Pressure stability and flex
Standards SAE J2064, SAE J3062, QC/T 664 Passenger car & light truck A/C hose
Certification ISO/TS 16949:2009 Automotive quality system
Burst / WP (typ.) ≈ 4x working pressure / 20–35 bar WP By size; confirm per SAE lot test
Bend Radius (typ.) ≈ 60–110 mm Avoid kinks; route with clips

Process flow—how it’s built

  • Materials: EPDM compound blending, PA/NYLON barrier extrusion.
  • Methods: Co-extrusion of tube+barrier, spiral reinforcement wrap, cover extrusion, vulcanization, cut-length and crimp testing.
  • Testing: Permeation (SAE J2064), impulse cycles (up to ≈300k), burst, vacuum collapse, salt spray on fittings, ozone aging.
  • Service life: Designed for multi-year duty; fleet feedback shows 6–10 years in temperate climates.
  • Industries: OE passenger vehicles, aftermarket retrofit, light commercial, off-highway HVAC.

Where it fits and why it’s chosen

On compact cars, the Ac Hose From Compressor To Evaporator snakes past hot manifolds and sharp brackets. Mechanics like A20 because it routes cleanly and holds crimp. Many customers say cabin temps drop faster after replacing “mystery soft hoses” with this one—less micro-leak, steadier low-side pressures. In fact, I’ve seen it used on small electric vans where compressor duty cycling is aggressive; still behaved.

Vendor snapshot (buyers ask this first)

Vendor Standards Lead Time Customization Notes
KEMO A20 Type C SAE J2064/J3062, QC/T 664 ≈ 3–5 weeks Cut-to-length, fittings, private label ISO/TS 16949:2009 plant; solid pricing
Vendor B SAE J2064 ≈ 6–8 weeks Limited sizes Premium price, broad OE history
Vendor C House spec ≈ 2–4 weeks Basic Lower cost; check test data closely

Customization, testing, and a quick case

  • Customization: OD/ID ranges, pre-crimped ends, bracket clocking, ink-jet branding.
  • Test data (lab, typ.): Permeation ≤ 25 g/m²/yr (R134a), vacuum collapse pass at -100 kPa, salt spray ≥ 120 h on plated fittings.
  • Case: A taxi fleet in a humid coastal city cut recharge visits by ~30% after switching the Ac Hose From Compressor To Evaporator to A20; drivers noticed colder idle A/C, which is rare praise.

Industry trend watch

As vehicles shift to R1234yf and heat-pump HVAC in EVs, barrier performance and crimp reliability are the new battleground. To be honest, we’ll see more multilayer barriers and smarter fittings. This hose is already aligned with that trajectory without overcomplicating maintenance.

Final thought

Not flashy, but if you want your Ac Hose From Compressor To Evaporator to survive heat, vibration, and the occasional ham-fisted install, A20 Type C is a sensible, standards-first pick.
