Description
PRM Vapor Recovery Coaxial Hose for Fuel Dispensers
The PRM Vapor Recovery Coaxial Hose is a reinforced rubber hose assembly for gasoline fuel dispensers and Stage II vapor recovery systems. It combines the fuel delivery path and vapor return path in one compact coaxial assembly, helping fuel station operators build a cleaner, more organized and more reliable dispensing connection.
PRM supplies vapor recovery equipment for petrol stations, including nozzles, vacuum pumps, breakaways, separators and hoses. This hose series is available in standard 4.5 m and 6 m lengths, with custom lengths from 3.5 m to 10 m available for compatible projects.
Product Introduction
The Vapor Recovery Coaxial Hose is designed to connect a fuel dispenser with a compatible vapor recovery nozzle and related fittings. Its coaxial construction provides separate flow paths for gasoline delivery and recovered vapor return, allowing both functions to operate through one hose assembly.
The hose uses a strengthened black nitrile butadiene rubber structure and stainless steel threaded adaptors. It is engineered for regular petrol station use, with compact assembly, practical installation and connection options for vapor recovery dispensing systems.

Key Features
Coaxial fuel and vapor paths
The PRM Vapor Recovery Coaxial Hose integrates gasoline delivery and vapor return in one hose assembly, helping reduce external hose complexity at the dispenser.
Reinforced black NBR rubber construction
The internal reinforced rubber structure is designed for fuel station service conditions and frequent nozzle handling.
Secure threaded connection
Stainless steel threaded adaptors support connection with compatible vapor recovery nozzles, breakaways and dispenser fittings.
Low electrical resistance
Resistance between the two threaded ends is controlled at or below 5 Ω. System grounding and electrical continuity must still be completed according to the installed dispenser design.
Joint strength and leak resistance
The hose joint is tested for leakage at 0.5 MPa and is designed to withstand a 2000 N tensile force for 30 seconds without separation.
Flexible length options
Choose 4.5 m or 6 m standard hose lengths, or request a custom length from 3.5 m to 10 m for project-specific fuel dispenser layouts.
Applications
The PRM Vapor Recovery Coaxial Hose is suitable for:
Product Details
Reinforced hose body
The black rubber hose body is built with a strengthened internal layer to support stable handling and service life in dispenser applications.
Stainless steel adaptor
The threaded adaptor provides a durable connection point for compatible M34×1.5 assemblies.
Fuel and vapor recovery connection
The coaxial structure is designed to carry fuel and return recovered vapor through isolated passages within the same hose assembly.
Hose-end connection area
The connection should be matched with the correct nozzle, breakaway valve, swivel and dispenser fitting to ensure proper operation of the vapor recovery system.
Installation and Maintenance
Before installation, verify the thread type, hose length, nozzle connection, breakaway valve and dispenser interface. Installation should be performed by qualified service personnel with the fuel dispensing system isolated.
Inspect the hose regularly for cuts, cracks, abrasion, deformation, loose fittings or visible fuel leakage. Keep hose ends and threaded adaptors clean. Replace the hose immediately if damage, vapor leakage or connection looseness is found. Do not drag the hose across sharp surfaces or allow it to remain twisted during normal use.
Quality, Packaging and Supply
PRM lists factory testing for its vapor recovery hose assemblies. Standard packing is one hose per brown box; export wooden packaging can be discussed for bulk shipment or destination-specific requirements.
For an accurate quotation, provide the required length, quantity, thread specification, matching nozzle or breakaway model, target market and any packaging or OEM marking requirements.
FAQ
What are the standard hose lengths?
Standard lengths are 4.5 m and 6 m. Custom lengths from 3.5 m to 10 m are available.
Can the hose be used with any fuel nozzle?
No. Confirm the thread, adaptor structure and vapor recovery configuration before purchase. The listed threaded specification is M34×1.5.
What is the purpose of the coaxial design?
It allows fuel delivery and vapor return to operate through separate passages in one hose assembly.
Can PRM supply the complete hose assembly?
Yes. The hose can be matched with a compatible vapor recovery nozzle, breakaway valve, swivel or adaptor based on project requirements.
Is this hose suitable for all fuel types?
It is intended for gasoline vapor recovery applications. Confirm compatibility before using it with alcohol blends, alternative fuels or other liquids.
