Description

You’ve seen those mysterious coolant puddles under your tractor and traced them back to where the radiator connects to the reservoir tank. That small o-ring might not look like much, but when it’s worn out or cracked, it’ll let coolant leak out while air gets in—neither of which your cooling system needs. This replacement o-ring seals things up tight and gets your cooling system back to doing its job right.

What You’re Getting

Precise fit designed specifically for John Deere cooling system connections
Heat-resistant rubber that handles temperature cycling from cold starts to hot field work
Chemical-resistant construction that won’t break down in coolant over time
Direct replacement that seals properly without special tools or modifications

Built for Real Farm Work

This o-ring fits John Deere 6J, 6030, and 7030 series tractors—machines built for serious farming from row-crop work to heavy tillage. Whether you’re running a 6130 through corn harvest or pulling a deep ripper with a 7230, your cooling system needs every connection sealed tight to handle the heat these engines generate under load.

Made to Last

Coolant system seals live in a tough environment with hot fluid, pressure cycles, and chemical exposure from coolant additives. This o-ring uses materials specifically chosen to resist coolant breakdown while maintaining a flexible seal that won’t get brittle or crack over time.

Good to Know

Installation is straightforward—just make sure the connection surfaces are clean before installing the new seal. A quick wipe with a rag removes any old coolant residue or debris that could interfere with sealing. Check your coolant level after installation and top off if needed.
