A tiny part with a big job, the FTC3975 interlock retainer Oring helps seal critical components in your Land Rovers transfer box or interlock assembly, preventing lubricant leaks and keeping contaminants out. Over time, Orings can harden, flatten or perish due to heat and age, leading to oil weeping, accelerated wear on seals and joints, or noisy operation. Installing a fresh, quality Oring restores sealing integrity and supports smooth, reliable drivetrain performance.
Made to meet original specifications, this Oring delivers a close, flexible seal where its needed most. Though small, it plays an essential role in maintaining proper fluid retention and protecting internal components from moisture and dirt. Whether youre performing a gearbox rebuild, servicing the transfer box, or addressing a leak, replacing this seal is a simple, costeffective step that enhances longterm durability and helps preserve the health of your Land Rovers mechanical systems.
