Manuli UltraStar Refrigeration - Air Conditioning Hose

ULTRA-STAR, a low permeation AC hose in a class of its own.
ULTRA-STAR has been developed specifically to offer the mobile Air Conditioning and Refrigeration markets a compact steel braided all rubber hose that combines excellent flexibility and high kink resistance with a very low permeation rate.
SAE J2064 – Exceeds Type B Class 1

High mechanical strength all rubber hose with the benefits of an extremely low permeation rate (4.5kg/m2/year)

Product highlights:
  • Extremely low permeability
  • Excellent structural strength
  • Reduced bending radius on large sizes
  • Wide range of sizes available (from DN5 to DN35)
  • Full interchangeability with RefriStar (same dimensions and installation)
  • Same proven assembly solutions as RefriStar
  • Easy switch from RefriStar to improve refrigerant gas containment and reduce refilling costs
ULTRA-STAR uses an advanced rubber formulation which relies on a molecular barrier within the rubber compound to lower the permeation rate and so by greatly reduce loss of refrigerant.
The ULTRA-STAR permeation rate is so low that it falls well inside the SAE permeation specification set for type "C" and "E" hoses. This feature means reduces refrigerant loss over time, making the AC system more environmentally friendly and at the same time reducing the need for frequent refrigerant system top-ups.
