Quick Coupling / Quick Coupling Dust Plug

System Isolation & Protection: Installed on open female couplers attached to pipeline manifolds, tank trucks, rail cars, and bulk chemical transfer lines when the connection is broken.

Contamination Prevention: Essential for protecting the purity of high-grade fluids by blocking dust, insects, rain, and grit from entering open process piping.

Environmental & Workplace Safety: Prevents product dripping, fuming, and residual fluid leakage from open hose endpoints and connection terminals.

Restriction: Dust plugs are designed exclusively for containment and environmental isolation; they must not be used to seal fluid lines under pressure or in place of a structural blind flange.

Coupler Type: Part DP (Male Dust Plug)

Body Material Options: Available in three premium materials to match the physical and chemical requirements of your system:

• Stainless Steel: Maximum durability and ultimate corrosion resistance; highly recommended for aggressive chemicals, acids, and sanitary pharmaceutical/food lines.

• Aluminum: Lightweight, rugged, and highly economical; perfect for petroleum, fuel delivery, and general industrial lines.

• Polypropylene: Lightweight and entirely corrosion-free; optimized for agricultural chemical systems and liquid fertilizers.

Thread Standard: N/A (Features a solid, non-threaded structural design).

Gasket Required: N/A (As a male plug profile, the seal is achieved when it compresses against the elastomeric gasket housed inside the mating female coupler).

Size Range: 1″ to 4″

Brand: OPW (United States)

Global Interchangeability: Engineered to conform with standard global military and international specifications (A-A-59326 / MIL-C-27487), ensuring a precise, reliable fit into any standard female camlock coupler.

Lanyard Attachment Loop: Features an integrated heavy-duty loop profile on the body, allowing operators to attach a safety chain or wire cable to tether the plug directly to the hose or manifold, preventing it from being misplaced.

Rugged One-Piece Cast: Precision-cast structure withstands rough handling, dropping, and heavy outdoor environments without losing its dimensional integrity.
