1004D3 API Bottom Loading Coupler

The latest in API Bottom Loading Couplers, a proven performer at major oil terminals around the world.

5-Cam Design: Easy alignment, tight adaptor connections and side-force resistance during loading
Dual Interlocks: Ensure that opening cannot occur unless properly connected to an API Adaptor
Superior Sealing: Simple, reliable smart-seal design with dual high-performance O-rings
High-Performance Seals: Special Fluorocarbon Seal Compound for compatibility across most products, including gasoline, diesel, biodiesel and ethanol*
Maintenance: Pins and small threads eliminated to provide quick, easy access to critical components; nose seal replaced without requiring removal of coupler from rack; no special tools required; complete rebuild in minutes
Operation: Stainless-steel “ergo” handle design for easy, smooth operation
