High quality flexible hoses and metal components designed to deliver safety, durability and long-term reliability.

Quick Coupling / Vapor Recovery Coupler

     

 

Primary Application

  • Vapor Recovery Systems: Installed on vapor return lines to collect displaced gas during the high-flow bottom loading and unloading of bulk storage tanks and transport vehicles.

  • Bulk Product Logistics: Extensively used at petroleum terminals, chemical distribution centers, and refined fuel loading racks.

  • Fleet Refueling & Transport: Mounted onto the vapor recovery hoses of road tank trucks, rail tank cars, and transport trailers.

Structure & Specifications

  • Coupler Configuration: Female Camlock Coupler with an Internal Spring-Actuated Poppet Valve

  • Body Material: Aluminum (High-strength, spark-resistant, and exceptionally lightweight for easy operator handling)

  • Poppet Valve Profile: Buna-N Poppet (Features a resilient Buna-N elastomeric sealing surface to ensure a leak-tight, zero-emission shut-off)

  • Standard Gasket: Buna-N (Provides premium resistance to petroleum vapors, fuels, and typical hydrocarbons)

  • Size: 4″ x 4″ (4″ Female Camlock Connection x 4″ Line/Hose Connection)

  • Brand: OPW (United States)

Key Features & Benefits

  • Automatic Emission Control: The spring-loaded poppet provides a mechanical safety seal, ensuring that toxic or flammable vapors are locked inside the line the exact moment the connection is broken.

  • Closed-Loop Environmental Compliance: Helps facility operators meet strict environmental regulations and air-quality standards by eliminating product fuming and VOC venting during bulk liquid transfers.

  • Ergonomic & Durable Aluminum Build: The precision-cast aluminum structure easily handles the wear and tear of terminal environments while keeping the hose assembly light enough to reduce operator fatigue.

  • Standard Kamlok Locking Mechanism: Dual heavy-duty cam arms hold the mating adaptor tightly against the internal gasket, creating a positive seal that resists line pulsing and physical movement.

  • Mil-Spec Dimensional Interchangeability: Built to conform with standard global military and international specifications (A-A-59326 / MIL-C-27487), ensuring a reliable, secure fit with any standard 4″ matching male vapor adaptor.
