Product Questions & Answers (2)

Question by: Lynn C on Sep 25, 2025, 11:22 AM
Got a hydraulic line coming off a pump with a 1/2 NPT female port and I need to tie into a SAE O-ring boss fitting that's 1-5/16-12. This the right adapter for that?
Answer by: Customer Support on Sep 26, 2025, 4:09 PM
Yeah, that's exactly what this one's built for. One end is 1/2-14 female NPT and the other is 1-5/16-12 male SAE O-ring boss, so it bridges those two thread types in a straight configuration. No additional thread sealant is needed on the ORB side since the O-ring handles the seal. Just make sure your NPT port is clean and in good shape before threading it in.
Question by: Keith G on Aug 4, 2025, 6:09 PM
So, will this adapter hold up if I'm running hydraulics pretty much all day long?
Answer by: Customer Support on Aug 5, 2025, 6:56 PM
Crafted from high-grade steel, this adapter offers exceptional durability, even with long-term use in harsh conditions.
