Description

There’s nothing worse than finding an oil spot under your tractor or discovering engine coolant where it shouldn’t be. A worn cylinder block plug o-ring might seem like a small thing, but when it fails, it can let vital fluids leak out and contaminants leak in. This replacement o-ring restores that critical seal and keeps your engine running like it should.

What You’re Getting

Precision-molded o-ring designed for exact fit in cylinder block plug applications
Oil and coolant-resistant material that handles temperature extremes and pressure cycles
Direct replacement for worn or damaged original seals
Factory-spec dimensions ensure proper compression and sealing

Built for Real Farm Work

This o-ring fits New Holland T4, T5, T6, and T7 series tractors that see diverse agricultural work from specialty crops to heavy row-crop operations. Whether you’re running a compact utility model for vineyard work or a high-horsepower machine for intensive farming, these tractors depend on proper engine sealing to maintain performance when the work gets tough.

Made to Last

Engine block plugs face constant exposure to hot oil, coolant, and vibration. This o-ring is made from materials that resist swelling, cracking, and hardening even after thousands of hours of operation. The flexible seal maintains its grip through temperature swings and pressure changes that would cause inferior seals to fail.

Good to Know

When replacing the o-ring, clean the plug and block surfaces thoroughly to remove any old sealant or debris. A light coating of engine oil on the new o-ring helps it slide into place without damage. Don’t overtighten the plug – the o-ring does the sealing work, and too much torque can distort the seal or crack the block.
