NGV2 CNG Filling Connector for Vehicle Gas Systems
This listing covers a CNG filling connector identified as NGV2 in the product information. Confirm the exact component type, interface drawing and mating equipment before ordering. Do not assume the product name establishes compliance with a particular connection standard.
The filling interface and pipe connection must be checked separately. Identify whether the supplied component is a vehicle-mounted receptacle, a dispenser-side nozzle or another connector arrangement. These parts serve different roles.
Technical Specifications
The following values are listed in the product information. Confirm their definitions and rated conditions against the technical sheet for the supplied component.
| Listed Product Reference | NGV2; confirm the exact interface designation |
|---|---|
| Fuel Application | CNG — compressed natural gas |
| Listed Rated Pressure | 20 MPa; confirm rating basis, permitted conditions and mating-equipment requirements |
| Listed Nominal Diameter | DN 4; confirm the dimensional definition in the drawing |
| Pipe Connection | Listed as a ferrule-type connection; request tube size, fitting details and sealing specification |
| Filling Interface | Request the specific standard or dimensional specification and compatible mating connector |
| Listed Net Weight | 270 g; confirm included fittings and accessories |
| Valve Functions | Confirm check-valve, shutoff and relief functions separately |
Will It Match Your Refueling Equipment?
Compatibility requires an identified mating interface. A general “GB/T quick coupling” description is insufficient. Request the exact standard number and edition where applicable, or a complete dimensional specification.
Component role: Vehicle receptacle, dispenser nozzle or other connector.
Mating interface: Approved connector reference and dimensional drawing.
Pressure: Ratings and operating conditions for both connected components.
Pipe fitting: Tube dimensions, ferrule arrangement and required mating parts.
Mounting: Support, access, orientation and installation clearance.
Similar names do not establish interchangeability. Do not connect components solely because they are described as NGV1 or NGV2. Verify the actual interface and documented compatibility.
Which Valve Functions Are Included?
Check valves, shutoff valves and relief devices have different functions. Request a function diagram for the supplied connector. A statement that no relief device is included does not establish whether a check valve is present.
Permitted flow direction
Any integrated non-return function
Any manual or automatic shutoff function
Any pressure or temperature-triggered relief device
Required protection provided elsewhere in the installation
The connector must be assessed as part of the complete fuel system. Review our conversion kit component guide when checking installation scope.
Which Inspection Records Should Buyers Request?
Leak and connection-performance claims require documented test conditions. Request records covering the exact connector and mating arrangement.
Dimensions: Interface, fitting and sealing-surface checks.
Leak testing: Test medium, pressure, duration and acceptance limit.
Pressure testing: Test method and limits, distinguished from the operating rating.
Connection cycling: Number of cycles, mating component and acceptance criteria where claimed.
Traceability: Product reference, batch and inspection date.
Approval documents must identify the covered component and scope. Review our certification information and request applicable product records.
Frequently Asked Questions
Can this connector also be used for LPG?
This listing specifies CNG. LPG suitability is not established. Request components documented for the intended fuel and filling interface.
Does a 20 MPa rating guarantee compatibility?
Pressure rating is only one compatibility requirement. Confirm the interface, mating equipment, temperature conditions, pipe fittings and installation requirements.
Can the listed pipe fitting connect directly to a cylinder?
The pipe fitting does not identify a cylinder-neck connection. Use the technical drawing to confirm the connector's location and mating parts within the filling circuit.
Where should it be installed?
Installation depends on the component's actual role and approved arrangement. Follow the supplied mounting instructions. Do not assume an engine-bay location from product weight or size alone.
Is customization available?
Customization requirements need technical review. Provide drawings, interface requirements, intended fuel and quantity. Confirm validation, documentation and lead time before ordering.
Who should install and inspect it?
Qualified CNG personnel should perform installation and commissioning. Follow component instructions and applicable local requirements. Request approved inspection and service procedures.
Request a CNG Filling Connector Quotation
Send the required component role and mating-interface details. Include drawings or photographs, pressure requirements, pipe connection specifications, destination country and quantity.
Confirm the complete supply scope before payment. Request the exact product reference, included fittings, valve functions, test documents, price, warranty and delivery lead time.
