Material & Advantages

1. Imported HNBR hydrogenated nitrile rubber formula, excellent resistance to compressed air moisture, gear oil erosion and high-temperature aging

2. Precision one-step molding profiled lip structure, perfect fit piston outer circle, strong lip self-tightening force under air pressure to avoid gap leakage

3. Anti-extrusion compound formula, not easy to deform or crack under long-term high air pressure reciprocating friction

4. Standard OEM size 22×36×14.5, fully matched with piston 0501 328 038, no trimming or modification required during overhaul

5. Low friction surface treatment, reduce piston reciprocating resistance, speed up high-low gear switching response

6. Adapt to long-distance full-load highway logistics, mountain heavy climbing and high-frequency half-speed switching heavy transport working conditions

Application Scenarios

• Replace worn, hardened, air-leaking original cylinder oil seal marked 0750 112 047 for ZF 16-speed Ecosplit4 gearbox

• Fix transmission faults including delayed high-low range shift, unable to switch half-speed, abnormal large air consumption of air compressor, gear engagement lag

• Complete auxiliary box splitter cylinder disassembly overhaul and regular maintenance for fleets equipped with ZF 16-speed manual gearbox

• Assemble matched splitter piston 0501 328 038 and cylinder housing following official ZF pneumatic circuit assembly standards; recommended to replace together with the piston during full overhaul

Supply & After-sale

• MOQ: 1 piece

• Warranty: 3–6 months (exclude contaminated compressed air, improper piston installation, sharp scratch damage and natural rubber aging)

• Packaging: Independent sealed plastic bag + shockproof foam carton packaging to avoid lip scratch and extrusion deformation

• Remarks: Confirm gearbox model ZF 16S Ecosplit4 series; this seal only matches piston 0501 328 038, not interchangeable with other size sealing rings
