Reliable Sealing for Harsh Environments
Bulb trim seals are edge-mounted or vertical mounted profiles that provide compression-style sealing for doors, hatches, and panels. The bulb compresses when the door closes, forming a tight seal against external elements while reducing rattle, vibration, and wear.
We offer a wide selection of edge or vertical bulb trim seals and can accommodate custom requests to meet unique dimensional, environmental, or industry-specific requirements.
Common Applications:
- RV and trailer doors
- Construction and off-road vehicle cabs
- Agricultural machinery enclosures
- Marine hatches and access points
- Electrical cabinets and HVAC units
Material Options and Installation Flexibility
Our bulb trim seals are available in rubber-like materials including EPDM, PVC, silicone, and dual durometer compounds, giving you options tailored to your sealing needs—whether you need resistance to weather, UV, temperature extremes, or chemicals.
Available Installation Methods:
- Push-in
- Clip-on
- Slide-in
- Adhesive bonding using high-strength acrylic foam tape
We also integrate metal carriers into co-extruded profiles to enhance grip and form stability—especially useful in curved or vibration-prone installations.
