This CNG manual filling valve acts as the essential refuel access port for vehicle CNG autogas conversion kits. It enjoys huge market demand among auto repair garages, gas-conversion installers and spare-parts importers all over Latin America. Widely fitted on taxi fleets, second-hand passenger cars and light-duty commercial vehicles doing petrol-to-gas modification in Brazil, Mexico, Argentina, Colombia, Peru and Chile. Local mechanics prefer this high-pressure gas valve for brand-new conversion kit assembly and worn-out valve replacement work for aging vehicle fleets.
Constructed from high-strength brass material, this manual filling valve serves as the dedicated filling inlet for compressed natural gas. Built-in check-valve structure effectively prevents gas back-flow after refueling. Equipped with manual switch handle and protective dust cap, it delivers reliable sealing performance under high-pressure working conditions. It can match mainstream CNG cylinder pipelines and conversion system fittings, supporting safe and convenient CNG refueling operations for retrofitted bi-fuel vehicles. Bulk-order custom requirements for thread types and packaging can be supported.

Application Scope
This CNG manual filling valve is the core refueling port component for petrol-to-CNG bi-fuel vehicle conversion systems. It applies to retrofitted passenger cars, taxis, light-duty commercial vehicles and large-size fleet vehicles. Ideal spare-part supply for auto repair workshops, autogas installers and spare-part importers covering Latin America (Brazil, Mexico, Argentina, Colombia, Peru, Chile), Southeast Asia, Middle East and Africa markets. It can be assembled into full autogas conversion kits or sold separately as aftermarket replacement spare parts.
FAQ
Q1: What is the main function of this CNG manual filling valve on autogas conversion kits?
A1: It works as the dedicated refueling inlet for CNG gas cylinders. The built-in check-valve prevents gas back-flow after refueling, and the manual handle can cut off gas flow for maintenance work.
Q2: Is this filling valve suitable for taxi fleet retrofit projects in South-American countries?
A2: Yes. This brass filling valve is widely adopted for taxi and second-hand car CNG retrofits. The corrosion-resistant brass body performs well under hot and humid tropical road conditions.
Q3: Can you support custom thread specifications or custom packaging for bulk orders?
A3: Custom requirements for thread types and export packaging are available for large-volume orders. Please clarify your detailed technical requirements while sending purchase inquiries.
Q4: Can I install this CNG filling valve by myself without professional technicians?
A4: Installation must be completed by experienced autogas conversion technicians. High-pressure CNG system requires strict leak-test after mounting to eliminate potential safety hazards.
Q5: When do I need to replace the CNG manual filling valve on converted vehicles?
A5: You need replacement when there appears gas leakage, hard manual-handle rotation or valve-core aging. Regular inspection of the dust cap and sealing condition is recommended for fleet vehicles.
Manufacturing & Quality Assurance
Every batch of CNG filling valves undergoes strict raw-material inspection, CNC dimensional checking and high-pressure air-tightness leakage testing. Supported by standardized metal-processing workflows, stable-quality autogas high-pressure spare parts can be supplied for global importers, wholesalers and vehicle-retrofit project customers.
