Professional O-Ring and Oil Seal Manufacturer, Sealing Solution Supplier Since 2008.
High - Quality SPNO Seal with Bronze PTFE (BT12) Wear Ring and O - Ring
Reliable Sealing Component for Challenging Operating Conditions
Introducing the high-performance SPNO Seal, a reliable sealing solution designed for demanding scenarios. It combines a premium elastic O-ring (ensuring tight initial sealing and adapting to minor gap changes) with a BT12 Bronze PTFE wear ring—boasting low friction, strong wear resistance, and enhanced thermal conductivity via bronze filling.
This seal effectively prevents fluid leakage (liquids/gases) and blocks external impurities, guaranteeing stable equipment operation. Its durable structure extends service life, reducing maintenance frequency and costs. Perfect for hydraulic cylinders, pneumatic components, and industrial machinery, it delivers consistent performance even in harsh conditions, making it a smart choice for boosting operational efficiency.

1. Product Advantages
The SPNO Seal from Forever Seals stands out with dual-core strengths: a premium elastic O-ring ensures tight initial sealing and adapts to minor gap fluctuations, while the BT12 Bronze PTFE wear ring offers ultra-low friction, excellent wear resistance, and enhanced thermal conductivity (thanks to bronze filling). It boasts long service life, reducing equipment maintenance frequency and operational costs. Compared to ordinary seals, it maintains stable performance in harsh environments (e.g., high pressure, temperature variations), delivering reliable sealing even under extreme conditions.
2. Working Principle
This seal operates through a synergistic design: the O-ring, with its inherent elasticity, deforms to fill sealing gaps, creating an initial barrier against fluid (liquid/gas) leakage. The BT12 Bronze PTFE wear ring acts as a protective layer—its low-friction surface minimizes abrasion between the seal and mating parts, preventing O-ring wear and extending the entire assembly’s lifespan. Together, they block external dust and impurities, ensuring internal equipment components stay clean and function smoothly.
3. Product Details
Materials: O-ring (high-quality elastic rubber, resistant to oil and aging); BT12 Bronze PTFE wear ring (food-grade PTFE + bronze powder, non-toxic and corrosion-resistant).
Structure: Precise dimensional control (compliant with industrial standards) ensures easy installation in standard sealing grooves.
Color: O-ring (black, customizable); wear ring (natural PTFE color with bronze flecks, visible material quality).
4. Application Range
Ideal for industries and components requiring high sealing reliability:
Hydraulic systems: Hydraulic cylinders, valves, and pumps.
Pneumatic equipment: Pneumatic cylinders and air compressors.
Industrial machinery: Construction machinery (excavators, cranes), automotive transmissions, and medical equipment (low-corrosion scenarios).
5. FAQ
Q: Can the SPNO Seal withstand high temperatures?
A: Yes. The BT12 Bronze PTFE wear ring resists temperatures up to 260°C, and the O-ring (optional high-temperature rubber) can adapt to -20°C to 180°C, suitable for most industrial temperature ranges.
Q: Is it compatible with different fluids?
A: Absolutely. It works with hydraulic oil, mineral oil, water-based fluids, and inert gases; contact Forever Seals for custom solutions for special corrosive media.
