CT1 Seal O-Ring for Seal Plate

The CT1 Seal O-Ring for Seal Plate is a precision rubber component engineered for use in quick-change systems, specifically designed for Bulldog-pattern platforms. This o-ring serves as a critical sealing element that maintains pressure integrity and prevents fluid or gas leakage at the interface between the seal plate and other system components. Operators and gunsmiths rely on this component to ensure consistent performance and reliability in tactical and professional shooting applications where seal integrity is non-negotiable.

Manufactured by Diversified Machine under MPN RRC-1003, the CT1 Seal O-Ring is constructed from durable elastomer material selected for chemical resistance and durability under operational stress. The o-ring's compact profile—measuring 4.3 x 0.6 x 5.05 inches—allows it to fit precisely within Bulldog quick-change seal plate assemblies without adding bulk or weight. The rubber composition is engineered to maintain elasticity across temperature ranges and withstand repeated compression cycles inherent to modular firearm systems, ensuring the seal remains effective across extended use periods.

This o-ring is essential for armorers, gunsmiths, and operators maintaining or assembling Bulldog quick-change equipped firearms. Installation is straightforward—the o-ring seats into the seal plate groove, creating a pressure-tight interface that prevents leakage during operation. Whether you're servicing an existing platform or building a new system, having spare CT1 Seal O-Rings on hand ensures you can perform maintenance without downtime. Each o-ring is sold individually, allowing you to stock replacements as needed for your operational requirements.
