O-Ring

O-Ring for John Deere Remotes

The A-R74210 O-Ring is a precision sealing ring designed for John Deere hydraulic remote couplers and related hydraulic connections found on tractors such as the John Deere 5410 and similar models. Manufactured from durable H4C elastomer material with a 75 durometer hardness, this O-ring provides dependable sealing performance under hydraulic pressure while resisting wear and fluid exposure. With a 0.796" inside diameter and 0.139" cross-section width, it fits standard 211 series sealing applications, helping prevent leaks and maintain proper hydraulic system performance. It’s a small part that does an important job—keeping hydraulic oil inside the system where it belongs.
