Question by: Howard H on Feb 18, 2026, 5:46 PM

Reckon this would be the right seal for a hydraulic cylinder with a 3/4 inch rod?

Answer by: Customer Support on Feb 20, 2026, 6:57 AM

This seal is sized at 3/4 x 1-1/8 x 5/16 inches, so it should fit a hydraulic cylinder with a 3/4 inch rod, assuming those are the correct dimensions for your application.
