800161599 t-shaped seal ring XCMG XE2000 excavator spare parts

XCMG XE2000 excavator T-shaped seal ring 800161599 | Original factory fit, two-way sealing, oil resistant and anti-aging

In heavy-duty operations such as mining and infrastructure construction, the seals on the hydraulic cylinder pistons and valve group sealing grooves of the XCMG XE2000 are prone to leakage due to insufficient one-way sealing and poor oil resistance. This leads to a drop in hydraulic system pressure, oil loss, and even cylinder wear and valve group jamming, increasing maintenance costs by tens of thousands of yuan. XCMG’s original T-shaped seal ring 800161599 is specifically designed for the XE2000 fluid system, offering three major advantages: precise fit, two-way leak prevention, and long-lasting oil resistance. It solves the pain points of traditional seal ring failures, safeguarding the sealing safety of the hydraulic system.

Three core advantages to build a solid sealing defense line

1. Original factory precise fit, with no sealing deviation.

It fully complies with the XE2000 hydraulic cylinder and valve assembly sealing groove design standard, with a T-section width tolerance of ±0.03mm, a height error of ≤0.02mm, and a 99.9% fit with the sealing groove;
It is compatible with common sealing positions in XE2000 hydraulic systems (such as boom cylinder piston and rotary motor valve group), and can be directly installed without cutting or grinding, avoiding the “sealing gap” caused by the size deviation of ordinary T-rings, and is compatible with the system’s maximum working pressure of 35MPa.

2. Two-way sealing prevents leakage, adaptable to dynamic operating conditions.

Adopting a “T-shaped structure + bidirectional sealing lip” design, the sealing contact area is increased by 60% compared to traditional O-rings, which can simultaneously block bidirectional leakage of hydraulic oil and maintain “zero leakage” even under dynamic working conditions of piston reciprocating motion (frequency ≤1.2 times/second);
Made of oil-resistant nitrile butadiene rubber (NBR + reinforcing agent), with a compression rebound rate of ≥92%, it can tightly fill the tiny gaps in the sealing groove, resist the sealing failure caused by system pressure fluctuations, and reduce hydraulic failures caused by leakage by 80%.

3. Oil-resistant and anti-aging, with a lifespan 1.5 times longer than ordinary rings.

According to third-party testing, after being immersed in 46# anti-wear hydraulic oil for 168 hours, the volume change rate was ≤5%, the hardness change was ≤10 Shore A, and there was no swelling or cracking. Its oil resistance performance far exceeds that of ordinary rubber rings.
The surface is treated with an anti-aging coating, and the temperature range is -40℃ to 120℃. It will not crack or soften in high-temperature mining environments (hydraulic oil temperature ≤65℃) or low-temperature winter operations.
With a service life of over 8,000 hours (compared to only 5,300 hours for ordinary T-rings), it reduces the frequency of replacement by more than 3 times, thereby reducing downtime maintenance costs.

Applicable to multiple scenarios, with traceable quality

Mining Excavation: Resistant to dynamic wear, ensuring leak-free sealing of boom cylinder and stick cylinder;
Heavy-duty infrastructure: oil-resistant and pressure-resistant, preventing sluggish operation caused by valve leakage;
Routine maintenance: Simple structure, easy to disassemble and assemble, replacement can be done without special tools;
Original factory triple testing (sealing test, oil resistance test, dimensional accuracy calibration), supports QR code traceability, and eliminates the risk of “easy leakage and easy aging” of aftermarket sealing rings.

Why choose 800161599?

Compared to aftermarket products: bidirectional sealing, leakage rate reduced to 0, lifespan increased by 50%;
Compared to ordinary T-rings: oil-resistant and anti-aging, more stable for dynamic working conditions;
Compared to universal sealing rings: no modification required, precisely matched to the XE2000 sealing station.
For XE2000 hydraulic cylinder leakage and valve group seal failure, select the original 800161599 T-shaped seal ring to protect the fluid system safety and reduce operational losses.
