Product Questions & Answers (3)

Question by: Brent K on Feb 25, 2026, 11:31 AM
Hey, will this wiper ring hold up if it gets real cold? I'm talking sub-zero temps.
Answer by: Customer Support on Feb 27, 2026, 7:57 AM
This Hercules ST Style Urethane Wiper Ring is rated to handle temperatures as low as -65°F, so it should perform just fine in those conditions.
Question by: Floyd R on Mar 26, 2026, 12:26 PM
Got a cylinder with a 4.50 inch rod that needs a new wiper, this the right size for that?
Answer by: Customer Support on Mar 28, 2026, 6:16 AM
For a 4.50 inch rod diameter, yes, this is the correct wiper ring. The outer diameter comes in at 5.25 inches with a 3/8 inch base thickness, so make sure your housing groove matches those dimensions before you drop it in. As long as the bore and groove geometry line up, it should seat right and do its job keeping contamination out of the cylinder assembly.
Question by: Wes F on Jul 2, 2025, 8:31 AM

Answer by: Customer Support on Jul 3, 2025, 3:02 PM
Fit comes down to the rod diameter and the wiper OD. This ST style urethane wiper ring is sized for a 4.50 inch rod diameter with a 5.25 inch wiper outer diameter, and it has a 3/8 inch base thickness.
