Description
4" Aluminum Female Vapor Recovery Coupler x 3" Hose Shank w/Probe
4" Aluminum Female Vapor Recovery Coupler x 3" Hose Shank w/Probe provides a dedicated connection for compatible vapor recovery hose assemblies used in petroleum transfer systems.
Constructed from 356T6 aluminum, the Dixon 4030-CVR-AL combines a 4" vapor recovery coupler with a 3" hose shank and integral probe. The assembly uses a nitrile rubber gasket with bronze cam arms and stainless steel arm pins.
Product Highlights
Aluminum vapor recovery coupler designed to connect compatible 4" equipment to a 3" vapor recovery hose.
The 4030-CVR-AL includes an integral probe, nitrile gasket, and bronze cam arms for vapor service.
Technical Specifications
Vapor Recovery Connection Configuration
The 4" coupler engages compatible vapor recovery equipment and uses bronze cam arms to secure the mating connection.
The opposite end provides a 3" hose shank for compatible vapor recovery hose while the integral probe supports the intended vapor recovery connection.
Vapor Recovery Coupler Design
The Dixon 4030-CVR-AL combines a 4" female vapor recovery coupler with a 3" hose shank in one dedicated assembly. This configuration provides a direct connection between compatible vapor recovery equipment and a properly selected 3" vapor recovery hose.
Confirm both connection sizes before installation because the coupler and hose shank serve different portions of the recovery system. The 4" coupler should match the vapor recovery adapter, while the 3" shank should match the hose and attachment method.
The coupler body is manufactured from 356T6 aluminum for compatible petroleum vapor recovery applications. The lightweight metal body is combined with bronze cam arms, stainless steel arm pins, and plated carbon steel finger rings.
Inspect the coupler body, cam arms, pins, finger rings, and hose shank before installation. Components showing deformation, excessive wear, corrosion, or other visible damage should be serviced or replaced before the assembly is used.
The 4030-CVR-AL uses a nitrile rubber gasket to provide the sealing interface at the female coupler connection. An integral probe is included as part of the vapor recovery configuration and distinguishes the assembly from standard cam and groove couplings.
Inspect the gasket for cuts, flattening, contamination, or deterioration before making the connection. Verify the probe is intact and unobstructed, and confirm gasket compatibility with the vapor recovery system and fuel environment.
Dixon specifies the 4030-CVR-AL for vapor recovery service and for use with compatible vapor recovery hose. The fitting is not intended for liquid transfer service, so it should not be substituted for a conventional liquid-handling cam and groove coupling.
Verify the application, mating vapor equipment, hose size, gasket condition, and installation method before placing the assembly into service. Keeping the fitting within its intended vapor recovery function helps maintain the correct system configuration.
Installation & Selection Considerations
Confirm the 4" coupler size.
Verify the 3" hose shank.
Inspect the nitrile gasket.
Check the integral probe.
Use for vapor recovery only.
Our product specialists can help review coupler size, hose shank size, probe configuration, gasket material, and vapor recovery system compatibility before you order.
