Description / Abstract:
This SAE Standard covers fittings, couplers, and hoses intended
for connecting service hoses from mobile airconditioning Systems to
service equipment such as charging, recovery and recycling
equipment. (Figure 1) This specification covers service hose
fittings and couplers for MAC service equipment service hoses, per
SAE J2843 and SAE J2851, from mobile air-conditioning systems to
service equipment such as manifold gauges, vacuum pumps, and
airconditioning charging, recovery and recycling equipment.
Purpose
The purpose of this SAE Standard is to establish specific but
unique fittings, couplers, and hoses for service equipment used in
maintaining R-1234yf systems. This is necessary to avoid cross
mixing of refrigerant and lubricants from other refrigerant
systems. This standard applies only to systems specifically
designed to use R-1234yf. Hermetically sealed appliances and
refrigerated cargo systems are not covered by this document.
