Question by: Peggy G on Sep 24, 2025, 8:52 PM

Will this adapter hold up okay in a hydraulic system for a log splitter? Seems like it's made of decent steel.

Answer by: Customer Support on Sep 26, 2025, 6:21 AM

This steel adapter is designed for hydraulic systems requiring a reliable, leak-free connection between NPT-threaded components and JIC flare assemblies, so it should be suitable for log splitter applications.
