Product Questions & Answers (2)

Question by: Warren H on Aug 6, 2025, 10:50 AM
Got a hydraulic line that keeps weeping at the connection point and I'm pretty sure it's a sealing issue. Would this ORFS adapter help lock that down compared to what I got now?
Answer by: Customer Support on Aug 7, 2025, 3:40 PM
O-ring face seal connections are built specifically for that kind of problem. The ORFS configuration on this adapter creates a metal-to-metal contact with an O-ring backup, which gives you a positive seal rather than relying on thread contact alone. If your current setup is using a different connection type and you're seeing seepage, switching to ORFS is a well-regarded fix in high-pressure hydraulic circuits where leak-free performance matters.
Question by: Dale M on May 4, 2025, 7:56 AM
What size is the O-ring face seal on this adapter?
Answer by: Customer Support on May 5, 2025, 9:37 PM
This adapter uses a 0.50 inch O-ring face seal, which should give you a good, tight connection for your hydraulic lines.
