Vapour Recovery System | J0550

EMCO Wheaton’s J0550 vapor coupler is designed to accommodate high flow rates and low pressure drop.

When used as part of the wider tank truck vapor recovery system, this product can speed up loading and unloading times, while also minimising product losses.

Low Pressure Drop
Maximizes vapour flow for faster loading and unloading 

Reduced Product Loss
Supports efficient vapour recovery during transfer operations 

Universal Compatibility
Compatible with API RP1004 vapour recovery adapters 

Built for Long Service Life
Durable aluminium body with hard-wearing brass cams

This product has the lowest pressure drop in its class and will allow higher flow rates when incorporated into an effective vapor return set up. It’s specifically designed for use on the vapor return arm or hose found at a loading rack.

Coupling to the tank truck’s vapor adapter will open both valves allowing product to flow freely. The high flow characteristics achieved from this design are essential for vapor return when multi-compartment bottom loading is taking place.

Other features include a self-sealing valve and drain plug fitted at the base of the unit for quick release of any accumulated product. The unit also mates to all available vapor adapters made in accordance with API RP1004. An aluminium body makes this unt exceptionally durable to different environments. Hard-wearing brass cams are also fitted as standard to ensure a long service life.

The J0550 Vapour Coupler is designed for vapour recovery operations during petroleum tanker loading and unloading.

  • Petroleum road tankers
  • Bottom-loading systems
  • Loading rack vapour recovery systems
  • Multi-compartment tanker loading
  • Emission control systems
  • Vapour return operations
  • Fuel terminals and loading facilities
