Specifications for Parker FEM Series Couplers
NOTE: Parker is currently updating the design of the FEM couplings. As of August 2021, the 3/8" and 1/2" sizes are updated to the new design, the rest of the sizes are to follow. The new design has a higher pressure rating of 5,000 PSI, improved Sleeve-Lok functionality, and better corrosion resistance. Read more on our FEM Series Design Changes blog.
