Product Questions & Answers (2)

Question by: Joyce C on Aug 13, 2025, 4:43 PM
Will this fitting hold up okay in a hydraulic system running around 1500 psi?
Answer by: Customer Support on Aug 14, 2025, 9:50 PM
Yes, it should. These fittings are rated for working pressures up to 2000 psi, so 1500 psi is well within its limits, giving you a good safety margin.
Question by: Ricky J on Dec 3, 2025, 6:17 AM
fitting says it works with plastic tubing but does it need any extra parts for that or does everything come with it?
Answer by: Customer Support on Dec 4, 2025, 8:06 PM
For some plastic tubing types, inserts are required to get a proper seal and keep the tubing from collapsing under the ferrule. Those inserts are not included with the fitting itself, so you'd want to confirm whether your specific plastic tubing requires them before assembly. Copper and aluminum tubing generally go in without extras.
