Rubber Vacuum Cap
Rubber Vacuum Cap Manufacturer
Rubber vacuum caps are small, flexible, cylindrical or round caps with a smooth surface, designed to fit tightly over vacuum ports to prevent air ingress and maintain system vacuum; some feature tapered walls or pull-tabs for secure, easy removal.
Common Rubber Vacuum Cap Materials
Material choice is critical for long-term sealing under vacuum, especially when exposed to oil vapors, ozone, temperature cycling, or chemical environments. We offer the following elastomers, each engineered for specific challenges:
• NBR
• EPDM
• Silicone
• CR
• FKM
