Product Questions & Answers (2)

Question by: Danny J on Jan 24, 2026, 1:09 PM
Will this fitting hold up okay in a hydraulic system with moderate vibration?
Answer by: Customer Support on Jan 26, 2026, 6:02 AM
This brass compression fitting is designed to offer fair resistance to vibration making it suitable for hydraulic systems where moderate vibration is present.
Question by: Dean H on Feb 7, 2026, 5:53 PM
Got 1/4 inch OD tubing running to a gauge on a pneumatic panel, will this elbow fitting work for that kind of setup?
Answer by: Customer Support on Feb 9, 2026, 6:11 AM
Pneumatic and instrumentation systems are both listed applications for this fitting, so that use case fits right in. The tube OD is 0.25 inch and the male NPT thread is 1/4-18, which is standard for a lot of gauge and panel connections. Just keep in mind that if you're running plastic tubing rather than copper or aluminum, you may need an insert to keep the tubing from collapsing under the compression sleeve. Metal tubing won't need that.
