Seal Cap Selection Guide

Choose TC (Threaded Cap) When:

• Standard storage protection is required
• Working with stable materials
• Cost-effectiveness is a priority
• Storage periods are moderate (up to 6 months)
• Industry-standard solution is preferred

Choose TS (Tri-Seal) When:

• Maximum protection is critical
• Long-term storage is anticipated (6+ months)
• Working with sensitive or expensive materials
• Materials are prone to rapid curing
• Harsh storage environments exist
• Zero contamination tolerance is required

Choose SC (Seal Cap) When:

• Economical solution is desired
• Standard protection is adequate
• Frequent cap removal and replacement occurs
• Short to medium-term storage (3-6 months)
• High-volume operations require cost efficiency

Choose Black Spike Tip Cap When:

• Protecting syringe dispensing tips
• Sealing luer-lock connections
• Working with fine-gauge needles
• Differentiating tip caps from cartridge caps
• Precision dispensing equipment is used

Best Practices

Installation

1. Clean Threads – Ensure cartridge threads are clean and free of material
2. Hand-Tighten – Install seal cap firmly but avoid over-tightening
3. Visual Check – Verify red cap is properly seated
4. Label Cartridge – Mark date sealed for inventory management
5. Store Properly – Keep cartridges in recommended temperature range

Storage Recommendations

• Store sealed cartridges in cool, dry environment
• Avoid direct sunlight exposure
• Maintain temperature between 60-80°F when possible
• Keep away from heat sources
• Use FIFO rotation system
• Inspect seals periodically for integrity

Removal

• Remove seal cap just before use
• Inspect material condition before dispensing
• Check for any signs of contamination or curing
• Dispose of used caps properly
• Replace with new cap if cartridge will be stored again
