Clean transfers. Reliable seals. Proven performance.

Terriva Dust Cap Seals create dust-tight connections between containers, helping you achieve clean, safe, and efficient powder transfer. Designed to integrate seamlessly with Terriva Neck Rings and Chutes, they prevent dust escape during filling, discharge, and handling — maintaining a controlled, contamination-free environment.

Manufactured from FDA-compliant silicone rubber, Dust Cap Seals are available in mid-blue or translucent finishes, both meeting CFR (FDA) standard 177.2600 for regulated industries. When correctly mounted on Terriva rings, each seal withstands up to 0.25 Barg over-pressure, ensuring a secure seal even as product is first discharged.

Each seal is precision die-cut to remove rough edges and prevent rubber particles that could contaminate your process. Our factory die-cutting service guarantees consistent, clean apertures for optimal performance.
