Syringe Rubber Gasket
Syringe rubber gaskets are precision-molded sealing components used in disposable and reusable syringes to ensure smooth plunger movement, leak-free sealing, and accurate drug delivery. They play a critical role in maintaining dosage accuracy, sterility, and user safety in medical and pharmaceutical applications.
Manufactured under controlled conditions, these gaskets are designed to deliver consistent friction performance, chemical stability, and long-term elasticity when in contact with pharmaceutical formulations, water-based solutions, and injectable drugs.
Key Functions of Syringe Rubber Gaskets
- Provide reliable sealing between plunger and syringe barrel
- Ensure smooth and controlled plunger movement
- Prevent leakage and backflow during injection
- Maintain consistent dosing accuracy
- Support safe and hygienic drug delivery
Engineering Note: A syringe gasket must balance low friction and sufficient sealing force. Poor material selection may lead to leakage, unstable glide force, or inaccurate dosing.
Material Options & Performance Characteristics
| Material | Typical Temperature Range | Application Suitability | Key Benefits |
|---|---|---|---|
| Medical Grade Silicone (VMQ) | -50°C to +200°C | Disposable & prefilled syringes | Excellent biocompatibility, stable elasticity, low extractables |
| Butyl Rubber (IIR) | -40°C to +120°C | Pharmaceutical syringes | Low gas permeability, good chemical resistance |
| Chlorobutyl / Bromobutyl | -40°C to +120°C | Drug-contact sealing components | Improved purity, reduced interaction with drugs |
Material Guidance: Medical-grade silicone and butyl-based elastomers are the most commonly used materials for syringe gaskets due to their stability, cleanliness, and compatibility with injectable drugs.
