Product Questions & Answers (1)

Question by: Gary W on Oct 30, 2025, 5:35 PM
Will this fitting hold up ok in a power steering system? I know those can get pretty hot.
Answer by: Customer Support on Oct 31, 2025, 6:00 PM
This adapter is rated to operate as low as -65F, so it should be resilient enough for power steering applications, which are listed as one of its intended uses.
