Reckon this'll hold up in a hydraulic system running around 5,000 psi?
Answer by: Customer Support on May 18, 2025, 2:49 PM
With a maximum dynamic pressure capability of 5,500 psi, this hex nipple is designed to handle that pressure safely.
Question by: Gary F on Feb 7, 2026, 7:03 PM
got a 3/4-14 NPTF female port on both ends, will this hex nipple tie em together?
Answer by: Customer Support on Feb 9, 2026, 9:02 AM
For joining two NPTF female ports, it gives you male NPTF threads on both sides in 3/4-14, so it’s a straight-through hex nipple meant to connect those two ends.
