The Massey Ferguson 3004939X1 O-ring provides a critical sealing function within the trailer brake valve, maintaining stable hydraulic pressure to support safe and consistent brake operation. It prevents fluid leakage that can compromise braking responsiveness, especially during heavy towing work.
Manufactured to DIDC 70 PL specification, this seal uses high-grade elastomer materials designed for durability, precise compression, and resistance to heat and hydraulic fluid exposure.
Produced by AGCO as a genuine OEM component, the O-ring is built to strict engineering tolerances, ensuring consistency, reliability, and exact fitment within the brake valve assembly.
Ideal for operators maintaining Massey Ferguson tractors across the 3600, 5400, 5600, 6400, 6600, 7600, and 8100 Series who need dependable sealing performance to support safe trailer braking in agricultural environments.
