Quick Coupling / Quick Coupling Part D

     

Primary Application

  • Manifold & Valve Connections: Ideal for installation directly onto the male threads of storage tank valves, pipeline manifolds, and process equipment.

  • Bulk Transfer Logistics: Widely utilized on road tank trucks, rail cars, and bulk liquid chemical loading arms.

  • Refineries & Chemical Plants: Excellent for high-vibration applications or lines carrying volatile petroleum products, solvents, and industrial chemicals.

Structure & Specifications

  • Coupler Type: Part D (Female Coupler with Female Thread)

  • Body Material Options: Available in three heavy-duty materials to match system chemistry:

    • Stainless Steel: Maximum structural integrity and corrosion resistance for aggressive chemicals, acids, caustics, and sanitary media.

    • Aluminum: Lightweight, durable, and highly economical; ideal for fuels, lubricants, and water lines.

    • Polypropylene: Corrosion-free and cost-effective; optimized for agricultural fertilizers, liquid chemicals, and mild acids.

  • Locking Arms: Patented Twin-Kam™ arms (Features a unique dual-cam profile that provides a secondary detent lock to prevent the arms from unlatching if bumped or vibration occurs).

  • Pull Mechanism: Spring-Ring™ finger rings (Designed to stay low-profile and open automatically for quick, hassle-free access with heavy safety gloves).

  • Thread Options: Available in standard BSP or NPT internal threads for universal compatibility with regional piping configurations.

  • Standard Gasket: Buna-N (Premium fuel and oil-resistant elastomeric compound; alternative materials can be specified for aggressive chemicals).

  • Size Range: 1″ to 4″

  • Brand: OPW (United States)

Key Features & Benefits

  • Twin-Kam™ Arm Security: Unlike standard camlocks that can open under pressure spikes or physical impacts, the Twin-Kam™ design incorporates a patented detent that locks the arm tightly in place unless manually released.

  • Spring-Ring™ System: Specially engineered finger rings resist distortion and stay positioned for easy access, eliminating the frustration of rings getting trapped flat against the body under the cam arms.

  • Universal Interchangeability: Fully compliant with standard military and international specifications (A-A-59326 / MIL-C-27487), ensuring dependable compatibility with all standard matching male adaptors.

  • Precision Sealing: Heavy-duty internal compression ensures a leak-free interface against the Buna-N gasket, mitigating volatile organic compound (VOC) emissions and environmental spills.
