WebParker 285 features an elastomeric inner tube that creates a tight, high- integrity seal between hose and fit- ting.A nylon barrier provides low refrigerant permeation, while the tough elastomeric outer cover inhibits moisture ingression and protects from heat and ozone. Parkrimp compatible WebJan 20, 2024 · The scope of SAE J3062 covers hose intended for containing and circulating lubricant, liquid, and gaseous R-134a, R-152a, and/or R-1234yf refrigerant in automotive air-conditioning systems. The hose shall be designed to minimize permeation of the refrigerant, contamination of the system, and to be functional over a temperature range of -30 to ...

Webchain than do small molecules. Hence, the mobility selectivity, Di/Dj, always favors the permeation of small molecules over large ones. The sorption co efficient of gases and va pors is a measure of the energy required for the gas to be sorbed by the polymer, and increases with increasing condensability of the permeant. WebIn doing so, the refrigerant permeation rates for hoses shall be determined using the procedures specified in SAE J2064 (incorporated by reference in § 86.1) The annual rate of refrigerant leakage from an air conditioning system shall be rounded to the nearest tenth of a gram per year.
