Question by: Sherry W on Dec 4, 2025, 6:49 AM
does this adapter go straight from ORB to JIC without needing any kind of sealant tape or paste on the threads?
Answer by: Customer Support on Dec 5, 2025, 2:20 PM
The SAE O-Ring Boss end handles sealing through its o-ring, so no thread sealant is needed on that side. The JIC 37 degree flare end seals by metal-to-metal contact at the flare, which also eliminates the need for tape or paste. Both connection types are self-sealing by design when properly torqued, so you can put this in clean without reaching for the Teflon tape.
