Application of Urethane Dig Tube End
- Excavator Dipper Arms: The primary application, where it acts as a sacrificial liner to prevent the steel arm from gouging and bending during digging.
- Backhoe Booms: Used on telescopic and standard backhoes to protect the extending boom from debris and scratches.
- Material Handling Equipment: Ideal for protecting the arms of machinery used in scrap yards or demolition sites from sharp metal and concrete.
- Dredging Operations: Applied to the suction pipes and ladder frames of dredgers to withstand continuous abrasion from sand, silt, and small rocks.
- Hydraulic Shear Carriers: Protects the boom from falling debris when processing concrete and rebar, ensuring the machine's structural integrity.

Advantages of Urethane Dig Tube End
- Superior wear resistance for extended service life
- High impact strength prevents cracking under heavy loads
- Excellent chemical resistance to oils, solvents, and minerals
- Custom cast to match exact tube dimensions and mounting needs
- Lightweight yet durable for reliable heavy-duty performance
- Reduces noise and vibration during excavation operations
Why Choose Our Urethane Dig Tube End?
- Cost advantage: optimized compounds that reduce total life-cycle cost versus cheaper ones.
- Performance edge: published abrasion mm³, tensile, tear, and compression set for informed choices.
- Sample policy: 2–3 urethane formula samples available for field validation; shipping cost applies.
- Low MOQ: flexible small-batch production for pilot runs and OEM qualification projects.
- After-sales service: technical troubleshooting and warranty terms.
- Transparent pricing: sample, small-batch, and production quotes to fit budgets.
- Supplier reliability: China-based manufacturing with export documentation and QC traceability.
Case Studies: How Urethane Dig Tube End Solved Client Challenges
- Quarry in Australia: A client was replacing steel liners on their excavator every 4 weeks due to sharp, angular bluestone. After switching to our 60D hardness urethane dig tube end, replacement intervals extended to over 6 months, saving them thousands in labor and parts.
- Demolition Company in Germany: A contractor was experiencing frequent cracking in their excavator boom from the vibration of a hydraulic hammer. Our custom-fit, thick-walled urethane sleeve absorbed the shock and prevented further structural damage to the boom.
- Contractor in Canada: Working in heavy clay, a construction firm struggled with material sticking inside the dipper tube, reducing productivity. Our urethane end's non-stick properties eliminated the clay buildup, increasing their daily output by nearly 20%.
Selection Guide of Urethane Dig Tube End
When selecting a suitable urethane dig tube end, consider the following factors:
1. Tube Diameter
The most common sizes in hydrovac excavation are 6-inch and 8-inch dig tubes, which determine the inner diameter of the urethane tip.
2. Material Hardness
70-80 Shore A: flexible, suitable for soft soil excavation
85-90 Shore A: balanced wear resistance and flexibility
90-95 Shore A: heavy abrasion environments such as sand and gravel
Thicker wear layers improve durability but increase weight. Choose based on operating conditions.
4. Reinforcement Structure
Heavy-duty excavation operations may require steel insert reinforcement to improve structural stability.
5. OEM Compatibility
Ensure the urethane dig tube end matches existing vacuum truck connectors, flanges, or bush hog fittings.
How does the price compare to OEM steel parts?
Our urethane ends are generally very competitive with, or even lower than, OEM steel parts in initial price. However, because they last significantly longer, the total cost of ownership is much lower.
Can you provide parts for older, discontinued machines?
Yes, absolutely. Since we are a manufacturer, we don't rely on stocking OEM parts. We can reverse-engineer a custom Urethane Dig Tube End from your measurements or a worn sample, ensuring a perfect fit for any machine, regardless of age.
How about your after-sales service?
We offer technical support, quality feedback handling, and fast reorder service.
Are you a manufacturer?
Yes. We are manufacturer. Welcome to visit our factory.
Can you introduce your customized process ?
Yes. The process includes Share needs → design & quote → prototype (opt) → production → delivery.
How do you control your product quality?
We have 10 inspectors to carry out raw material inspection, process control ,first article inspection and final inspection.
How do you monitor the production process to avoid delayed delivery?
We use the ERP system to execute orders, and can check the order status and expected delivery time at any time.
What is warranty of products?
All of products with 3-6 months guarantee (except very frequently wearing parts).
How do you deal with after sales service?
We will response in 24 hours with solutions such as replacement or reworking.
How do you deal wtih customers' molds?
We have dedicated personnel to sort out and maintain molds regularly.
What about the lifespan of molds?
20,000 times for compressions molds and 30,000 time for casting molds
How long can you keep customers' molds for free?
Due to the large quantity of molds, we can keep the molds for free for 2 to 3 years even if no order.
If the molds are damaged or reach the lifespan , who will be responsible for it ?
Customers only need to pay mold cost once. We will cover the cost if molds are damaged or reach the lifespan.
