Question by: Lee A on Jun 28, 2025, 10:31 AM
been trying to figure out if this fitting works for refrigeration lines or if its strictly a hydraulic thing
Answer by: Customer Support on Jun 29, 2025, 12:12 PM
Refrigeration is actually one of the listed applications for this adapter, alongside hydraulic and pneumatic systems, LP and natural gas, instrumentation, and power steering. It's a brass 90-degree elbow that converts a 1/4-18 female NPT connection to a 5/8-18 male SAE 45-degree flare, so as long as those thread specs match up with what you're working with, you're in good shape for refrigeration use.
