Trusted Nylon 66 Sleeve Manufacturer – Anping County Boli Hardware Wiremesh Products Factory, established in 1998 with an annual export value of US$5–10 million, proudly presents our high-quality Nylon 66 Sleeve specifically designed for concrete sleepers. With a 15mm inner diameter and 2mm wall thickness, this sleeve offers exceptional impact strength and durability, ensuring reliable protection for railway and infrastructure applications. Our product is engineered to meet the rigorous demands of global markets, including North America, Europe, Asia, and beyond.
Product Overview
Our Nylon 66 Sleeve is a precision-molded component that provides a durable, non-corrosive barrier between concrete sleepers and fastening systems. It is ideal for use in rail tracks, precast concrete elements, and heavy-duty construction where high impact resistance and long-term stability are required. The sleeve's 15mm inner diameter fits standard bolts or rods, while the 2mm wall thickness delivers optimal strength without adding unnecessary bulk.
Key Features & Benefits
- High Impact Strength: Nylon 66 material offers superior toughness and resistance to mechanical shock, ensuring the sleeve withstands heavy loads and vibrations.
- Corrosion Resistant: Unlike metal sleeves, Nylon 66 does not rust or corrode, extending the life of concrete sleepers in harsh environments.
- Precision Dimensions: Inner diameter of 15mm and wall thickness of 2mm are manufactured to tight tolerances for consistent performance.
- Lightweight & Easy to Install: Reduces labor costs and handling time compared to heavier alternatives.
- Temperature Resistance: Nylon 66 maintains mechanical properties across a wide temperature range, suitable for both hot and cold climates.
- Customizable Options: Available in various lengths, colors, and packaging to meet specific project requirements.

Why Choose Our Nylon 66 Sleeve?
Our sleeves are manufactured using advanced injection molding processes to ensure consistent quality and dimensional accuracy. The high impact strength of Nylon 66 makes it a preferred choice for concrete sleeper applications where repeated dynamic loads occur. Compared to standard polyethylene or PVC sleeves, Nylon 66 provides superior mechanical properties and longer service life.
Applications:
- Railway concrete sleepers (tie plates, fastening systems)
- Precast concrete panels and slabs
- Heavy machinery anchoring
- Infrastructure projects requiring durable insulation or protection
Frequently Asked Questions (FAQ)
1. What is the difference between Nylon 66 and regular Nylon 6?
Nylon 66 has higher mechanical strength, better heat resistance, and lower moisture absorption compared to Nylon 6, making it more suitable for heavy-duty applications like concrete sleepers.
2. Can the sleeve be customized for different diameters?
Yes, we offer custom molding services. Please provide your specific inner diameter, wall thickness, and length requirements, and we can produce accordingly.
3. Is the sleeve resistant to UV and weathering?
Nylon 66 has good UV resistance when stabilized. For outdoor applications, we recommend using black or UV-stabilized grades. Contact us for more details.
4. How do I install the sleeve on a concrete sleeper?
The sleeve is typically placed over the bolt or rod before inserting into the sleeper's hole. Its precise fit ensures easy installation without special tools.
5. What is the minimum order quantity (MOQ)?
MOQ depends on the size and customization. For standard sizes, MOQ is usually 5000 pieces. For custom designs, it may vary. Please inquire.
6. Do you provide samples?
Yes, we offer free samples for evaluation. The buyer pays for shipping, and sample time is typically 5–7 days.
7. What is the typical lead time for bulk orders?
Lead time is 15–20 working days after confirmation of order and payment. For urgent orders, expedited production may be arranged.
8. Are your products compliant with international standards?
Our manufacturing process follows strict quality control procedures. While we do not hold specific certifications, our products meet common industry requirements for impact strength and dimensional accuracy. Please contact us for detailed test reports.
