Quick Coupling / Quick Coupling Dust Cap

Adaptor Protection & Sealing: Placed over open male adaptors on tank truck loading valves, storage tank inlets, rail cars, and stationary pipeline manifolds when fluid lines are disconnected.

Purity Maintenance: Vital for preserving product integrity by keeping dirt, grit, moisture, and insects out of open process systems.

Environmental & Operator Safety: Prevents product dripping, vapor emission, and residual fluid leakage from open terminal connections.

Restriction: Dust caps are engineered exclusively for environmental isolation and containment; they are not intended to hold back line pressure or replace a structural blind flange.

Coupler Type: Part DC (Female Dust Cap)

Body Material Options: Available in three premium materials to suit your operational and chemical criteria:

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

• Aluminum: Lightweight, rugged, and highly economical; ideal for petroleum, fuel distribution, and general industrial utilities.

• Polypropylene: Lightweight, cost-effective, and completely corrosion-free; optimized for agricultural chemical systems and liquid fertilizers.

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

Standard Gasket: Buna-N (Offers excellent oil, fuel, and weather resistance. Alternative elastomeric compounds are available to suit specific chemical requirements).

Size Range: 1″ to 4″
