Question by: Tommy M on Mar 8, 2026, 8:27 PM
Does this elbow adapter work for hydraulic lines, or is it mainly meant for other stuff like grease fittings and refrigeration setups?
Answer by: Customer Support on Mar 10, 2026, 7:36 AM
Hydraulic systems are listed right alongside grease, refrigeration, and instrumentation as intended applications for this adapter. The brass construction and NPTF threads make it a solid fit for those kinds of connections. Just keep in mind that fuel, LP, and natural gas use requires a special order rather than the standard version.

Will this fitting hold up okay in a hydraulic setup?

For hydraulic systems, this adapter is designed to provide a secure and leak-free fit, so it should do the job for you.
