Product Questions & Answers (2)

Question by: Dale M on Jan 29, 2026, 6:41 PM
Will this work on my brake lines, or is it more for fuel and steering?
Answer by: Customer Support on Jan 31, 2026, 3:45 PM
This adapter is definitely suitable for hydraulic brake lines, power steering, and fuel lines. It's also listed for transmission cooler lines.
Question by: Randy Y on Apr 23, 2025, 6:17 AM
fitting's got a 3/8-18 male NPT end on it -- will that thread straight into a standard NPT port without any extra sealing tape or compound?
Answer by: Customer Support on Apr 24, 2025, 10:14 AM
NPTF threads like the ones on the male end of this adapter are cut to a tighter tolerance than standard NPT, so they're engineered to form a pressure-tight seal through thread interference alone. That said, a lot of folks in fluid line work still apply thread sealant as a belt-and-suspenders measure, especially in fuel or brake applications where even a slow seep is unacceptable. Nothing in the design prevents you from using tape or paste, and it won't hurt anything.
