Standard Plastic End Caps | General industrial, low-cost applications | Material: Durable plastic (ASTM D3389, 500 abrasion cycles no failure) Temp Range: -20°C to 80°C (▲ vs basic plastics) | Cost-effective, lightweight, easy installation. | Limited chemical/oil resistance; ▲ symbol indicates improved durability over basic plastics. |
Standard NR Rubber End Caps | Moderate environments (e.g., HVAC pipes) | Material: Natural Rubber (ASTM D2000 Class 1) Temp Range: -20°C to 100°C | Flexible, moderate chemical resistance. | Poor ozone/oil resistance; requires frequent replacement in harsh conditions. |
Silicone End Caps (Product’s Option) | High-temp/chemical environments (e.g., automotive, labs) | Material: Silicone (ASTM D2240, 40-70 Shore A hardness) Temp Range: -60°C to 230°C (▲▲▲) Certifications: RoHS, CE | Extreme temp/chemical resistance (▲▲▲), flame retardant, UV stable. | Higher cost; less rigid than plastic for heavy-duty impact. |
Custom Non-Standard End Caps (Product’s Advanced Tier) | Specialized machinery, bespoke designs | Custom dimensions (▲) and materials (e.g., EPDM/NBR) Molding service: ISO 9001-certified | Perfect fit for unique applications; tailored material blends (e.g., oil-resistant NBR). | Higher cost, longer lead time; requires detailed specifications from clients. |
EPDM Rubber End Caps | Outdoor/water-exposed systems (e.g., irrigation) | Material: EPDM (ASTM D2000 Class 3) Ozone Resistance: ASTM D1149 (50 ppm, 72hrs) | Excellent ozone/weathering resistance; UV stable. | Poor oil resistance; heavier than plastic. |
NBR Rubber End Caps | Oil/fuel environments (e.g., automotive fuel lines) | Material: NBR (ASTM D2000 Class 2) Oil Resistance: ASTM D471 (70% swell in oil, 72hrs) | Resists oils/fuels; durable in mechanical stress. | Brittle at low temps (-20°C); less flexible than silicone. |
