these are going into an A/C refrigeration setup on some heavy equipment we run. the hose we're connecting is a -8 dash size. this fitting gonna work for that?
Answer by: Customer Support on Sep 15, 2025, 12:48 PM
For a -8 hose dash size, you're in good shape. That's exactly what this fitting is rated for, and the 0.75-inch end size lines up with standard connections in A/C refrigeration hose assemblies. The E-Z Clip system it belongs to was built with that kind of application in mind, so fitment on a -8 hose should be straightforward without any modification.
