Product Questions & Answers (2)

Question by: Lance S on May 16, 2025, 4:35 PM
Will this adapter handle hydraulic pressures without leaking?
Answer by: Customer Support on May 18, 2025, 6:22 AM
Engineered to maintain integrity under pressure, this steel adapter provides a secure and leak-free connection in hydraulic systems.
Question by: Bobby J on Oct 22, 2025, 10:59 AM
Got a JIC fitting on one end of my line and an ORB port on the other, does this adapter go between the two without needing tape or sealant on the threads?
Answer by: Customer Support on Oct 23, 2025, 8:26 PM
The SAE O-Ring Boss side handles sealing through the o-ring itself, so no thread sealant is needed there. The JIC 37-degree flare end seals by metal-to-metal contact at the flare seat. Between the two, you get a secure, leak-free connection without adding tape or compound to either end.
