Product Description

Product Overview

The Bost Industrial Hydraulic NBR Seal is a durable, oil-resistant sealing solution designed for hydraulic cylinders, pumps and valves. Made from high-quality NBR (nitrile butadiene rubber), this seal delivers reliable performance in demanding industrial environments and helps prevent leaks, reduce downtime and extend equipment life.

Key Features & Benefits

Reliable Oil and Wear Resistance

NBR material offers strong resistance to hydraulic oils, fuels and common lubricants, making it ideal for both static and dynamic sealing. It provides excellent abrasion resistance, minimizing wear over long service cycles.

Durability and Fatigue Life

Designed for continuous operation, Bost NBR seals resist compression set and fatigue, ensuring consistent sealing performance under repeated pressure and movement.

Versatility and Compatibility

Available in rod seals, piston seals, O-rings and custom profiles, Bost NBR seals fit a wide range of hydraulic equipment. They perform well across common temperature ranges encountered in industrial systems and are compatible with many mineral oils and synthetic fluids.

Frequently Asked Questions

What are the core advantages of Bost engineering plastics compared to ordinary plastics?

Bost engineering plastics feature ultra-high mechanical strength, high-temperature resistance (-50°C to 300°C), chemical corrosion resistance, and wear resistance. Compared to ordinary plastics, their service life is extended by 3 to 8 times, making them suitable for replacing metals in harsh environments.

What is the delivery lead time? Do you offer global logistics?

Standard products: 5–15 working days; custom modifications: 2–4 weeks. We support global air/sea freight and provide export customs clearance documents (including REACH/UL certifications).

What is the minimum order quantity (MOQ)? Do you support small-batch trial production?

The MOQ for standard products is ≥100kg. We support small-batch trial production (as low as 20kg) and provide mold testing reports and performance data feedback.

How do I select the appropriate engineering plastic grade for my product?

Selection should be based on parameters such as load conditions (e.g., pressure/friction), temperature range, medium contact (e.g., oil/acid), and regulatory requirements (e.g., FDA/RoHS). Our engineers can provide free material selection consulting and sample testing.
