This aluminum gas filter is listed for compatible autogas sequential injection systems. Connection options are described as 12 mm and 14 mm. Confirm the actual fitting dimensions, fuel phase and pressure rating before ordering.
The filter protects components downstream of its installed position. Follow the system diagram and flow-direction marking. Do not assume the same filter is suitable for high-pressure CNG or liquid-phase LPG service.
Technical Specifications

| Listed Maximum Working Pressure | 4.5 bar; confirm pressure reference and rated conditions |
| Listed Temperature Range | −40°C to +120°C; confirm component scope and operating conditions |
| Filtration Specification | Request particle-size rating, efficiency and test method |
| Flow Capacity | Request rated flow and pressure-drop data under stated conditions |
| Listed Minimum Order | 1 piece; confirm sample and delivery terms |
What Do 12 mm and 14 mm Refer To?
Connection dimensions must be identified on the drawing. Confirm whether the listed size describes the fitting outside diameter, recommended hose inside diameter or another dimension.
Inlet and outlet dimensions
Recommended hose specification
Connection profile and sealing arrangement
Specified clamp or retention method
Installation clearance and support requirements
Matching diameter does not establish hose suitability. Confirm fuel compatibility, pressure and temperature ratings for the hose and complete connection.
Where Should the Filter Be Installed?
The approved system layout determines filter position. Confirm the selected fuel phase, pressure conditions and intended downstream components. Follow the filter's flow-direction marking where provided.
Required position relative to the regulator and injectors
Expected pressure and temperature at that location
Permitted mounting orientation
Access for inspection and replacement
Compatible hoses, fittings and supports
A filter installed after the regulator does not filter the gas before it reaches that regulator. Describe the protected components according to the actual flow path. See our conversion kit component guide for system context.
How Should Filtration Performance Be Compared?
“High efficiency” requires a measured specification. Request the particle size, retention efficiency and test method. A micron value alone does not describe performance across all operating conditions.
Filtration rating: Particle size in μm and the stated rating definition.
Efficiency: Retention result at the specified particle size.
Flow: Test medium, flow rate, pressure and temperature.
Pressure drop: Clean-filter conditions and service limits where specified.
Service capacity: Contaminant-loading data where available.
Filter performance does not establish removal of every contaminant. Do not assume liquid, oil or moisture separation unless that function is specified and supported by test data.
Which Quality Records Should Buyers Request?
Routine inspection and filtration qualification are different checks. Request which tests apply to every unit, a production batch or the product design.
Leak testing: Test medium, pressure, duration and acceptance limit.
Pressure testing: Method and limits, distinguished from working-pressure ratings.
Filtration testing: Test method, conditions and results.
Connection checks: Dimensions and specified retention performance.
Traceability: Product reference, batch and inspection date.
Compliance statements must identify the covered filter. Review our certification information and request applicable product documents.
Frequently Asked Questions
Can this filter be used for both CNG and LPG?
Fuel and phase suitability must be confirmed for the supplied variant. Check the filter element, seals, housing ratings and intended installation position.
Can it be installed directly in the CNG cylinder-pressure line?
The listed 4.5 bar rating does not establish suitability for cylinder-pressure service. Use only within the documented pressure range and approved system position.
How often should the filter be replaced?
Follow the manufacturer's service interval and replacement criteria. Fuel quality and operating conditions may affect service requirements. See our gas system maintenance guide for background information.
Can the filter be cleaned and reused?
Reuse depends on the filter design and service instructions. Confirm whether the unit is disposable or has a replaceable element. Do not assume cleaning is approved.
Does uneven idle prove the filter is blocked?
Uneven idle has several possible causes. Qualified technicians should check gas supply, pressure, wiring, sensors, injectors and calibration before replacing parts.
Can I order a sample or combine it with other parts?
Sample and combined-order terms can be confirmed in the quotation. Specify the required connection version, quantity, other components and destination.
