Guide to EPDM Caps
What are EPDM Caps?
EPDM (Ethylene Propylene Diene Monomer) rubber caps are flexible end closures made from synthetic rubber known for its excellent resistance to UV rays, ozone, heat, and water.
EPDM caps are commonly chosen for their durability and performance as UV resistant rubber end caps, perfect for outdoor and marine applications.They are ideal for sealing, covering, masking, and protecting components in harsh or external environments; offering a snug, reusable fit across a wide temperature range.
Key Features & Benefits of EPDM Caps
Weather and UV-resistant
Built to endure rain, sun, and extreme conditions without fading, cracking, or degrading. Long-lasting protection for outdoor use.
Temperature tolerant (-40°C to +120°C)
Designed to perform reliably in extreme heat and cold, maintaining strength and stability across a wide temperature range.
Flexible fit for irregular or precision fittings
Engineered to bend without breaking, offering excellent adaptability and resilience under stress or movement.
Excellent for sealing and masking
Provides a secure seal and clean edges, ideal for protecting surfaces during painting, coating, or environmental exposure.
Available in Dome and Flat-end styles
Stocked in both Dome and Flat-end styles to suit different functional and aesthetic preferences.
Suitable for indoor and outdoor use
Durable and versatile—built to perform reliably in both indoor and outdoor environments.
Whether you're applying them to exposed bolts or delicate tubing, these high temperature EPDM caps offer reliable protection with minimal effort.
Popular Applications for EPDM Rubber Caps
These caps are commonly used across a wide range of industries, including:
- Automotive: covering bolts, pipe ends, and fuel line connectors
- HVAC systems: sealing copper tube ends to prevent moisture and dust ingress
