Marine Caisson Gate Seals / EPDM Watertight Door Seal
AlphaSeals® ASRSEPB70138X65 is a heavy-duty solid EPDM rubber seal designed for marine, water-control, and civil engineering applications. It is suitable for projects requiring strong compression performance, weather resistance, and long-term sealing reliability, such as marine doors, watertight doors, caisson gates, dry docks, flood gates, sluice gates, dam gates, and coastal infrastructure.
The seal features a large D-Profile / Bulb Profile cross-section with a stable base for installation on steel structures, clamping plates, or retaining bars. The bulb section works as the main sealing contact area against the door frame or sealing surface. When the door or gate is closed under compression, the rubber profile helps reduce gaps and improve water sealing performance.
Manufactured in Thailand by PTI Global Products Company Limited, this product is suitable for international buyers looking for a reliable supply source, custom rubber extrusion capability, technical support, and project-based production.
Key Features
1. Solid EPDM Rubber for Outdoor and Marine Use
Made from high-quality solid EPDM rubber compound, designed for resistance to weather, sunlight, ozone, humidity, rain, salt-air exposure, and outdoor operating conditions.
2. 70 ±5 Shore A Hardness for Heavy-Duty Compression
The 70 Shore A hardness provides a strong balance between rigidity and flexibility, making the seal suitable for large watertight doors and gate systems requiring stable compression sealing.
3. Large D-Profile / Bulb Profile Design
The bulb section helps absorb compression and compensate for sealing gaps, while the large base provides stable installation with clamping plates, steel retainers, or gate structures.
4. Suitable for Long-Term Engineering Projects
Designed to reduce the risk of cracking, hardening, early deterioration, and compression deformation under demanding outdoor and marine conditions.
5. Made in Thailand with Custom Production Support
Produced in Thailand with flexible communication, project support, custom profile development, and stable supply for maintenance, repair, and engineering projects.
