Elbow - size 10 hose, 5/8" "O" ring w/ 1/4" flare access port

The 040-1xxx series connectors are identical to the 040-0xxx series except that they include access ports.  Access ports come in two types - 1/4" flare and R-134a "Automotive" style.  In "Automotive" style connectors, a 13mm port is typically used on the suction (low pressure) side and a 16mm port on the discharge (high-pressure) side.  See additional instructions on the use of these fittings with the new Diesel Kiki and Sanden compressors.
