Custom Rubber Round Cap
Rubber Round Cap Manufacturer
Rubber Round Caps are engineered specifically for cylindrical pipe and tube ends, where uniform 360° sealing and retention are critical. The round geometry distributes insertion force evenly around the pipe OD, reducing localized stress and preventing tearing—something square or flat caps cannot achieve on circular ends.
Flexiparts produces fully custom rubber caps with no stock items, tailored to your needs for outer diameter (5–200mm), inner diameter tolerance (±0.2mm), wall thickness (1.5–8mm), durometer hardness (40–90 Shore A), and color coding.

- NR
- EPDM
- NBR
- Silicone
- CR
- PU
