Fully compliant with original 668810/6688100 OEM size standards. No cutting, drilling or modification required, supporting direct replacement for old or damaged connecting sleeves to save maintenance time and cost.
Precision machined inner wall ensures tight fitting with hydraulic pipes and fittings. It avoids hydraulic oil leakage and system pressure loss, maintaining stable working efficiency of corn mowing machine hydraulic system.
Adopts high-strength alloy steel material with excellent compression and impact resistance. Professional surface anti-rust coating adapts to harsh farm environments such as dust, humidity and crop residue abrasion.
Integral forging structure effectively prevents deformation and looseness caused by long-term vibration of mowing equipment. Ensures continuous and stable hydraulic power supply during high-intensity harvesting operations.
This 668810 / 6688100 hydraulic connecting sleeve is widely applicable to various brands of corn mowing machines, forage mowers and crop harvesting equipment with matching hydraulic connecting structure. It is mainly used for hydraulic pipeline connection and fixing of mowing machine working arms, hydraulic execution components and auxiliary hydraulic systems.
Ideal for agricultural equipment maintenance shops, machinery repair teams and farm machinery spare parts wholesale.
This sleeve is fully compliant with the OEM standards under parts numbers 668810 and 6688100, designed as a direct plug-and-play replacement.
It is made of high-strength alloy steel via a precision integral forging process, ensuring high pressure resistance and long-term durability under heavy farm usage.
Yes, the precision-machined inner wall is engineered to secure tight fittings with hydraulic lines, effectively avoiding oil leaks and system pressure drops.
Thanks to its professional surface anti-corrosion coating, it is highly resistant to dust, moisture, and crop residue abrasion, making it perfect for harsh agricultural conditions.
It is widely used in corn mowing machines, forage mowers, crop harvesters, and other agricultural hydraulic machinery featuring compatible hydraulic systems.
