Filling Interface and Outlet Connection Selection
This filling-port assembly uses a hot-forged, CNC-machined brass body and includes a non-return valve. The listed outlet thread is M14×1. Match the exact product version to the intended fuel and filling equipment before ordering.
The filling interface and outlet thread are separate connections. M14×1 identifies the listed outlet thread; it does not define the mating refueling nozzle or establish a quick-connect standard.
Product Specifications

What Must Match Your Installation?
Compatibility depends on the fuel, connections and operating conditions. Vehicle category alone is insufficient for selecting a filling port.
Fuel: Specify the intended gas and its service conditions.
Filling interface: Provide the mating connector reference or dimensional drawing.
Outlet: Confirm the M14×1 mating fitting and sealing method.
Mounting: Check dimensions, orientation, support and access clearance.
Operating limits: Match the documented pressure and temperature ratings.
Non-Return Valve Function
The non-return valve is designed to restrict reverse flow under specified conditions. Confirm the permitted flow direction, opening characteristics and reverse-leakage limits for the selected assembly.
Non-return, manual shutoff and pressure-relief functions are different. Select any required additional functions using the complete system specification.

Frequently Asked Questions
Can this filling port be used for both CNG and LPG?
Dual-fuel compatibility has not been established for this listing. Confirm the exact model, intended fuel, operating limits and mating interface before selection.
Does M14×1 mean it fits any filling nozzle?
No. The outlet thread does not define the filling interface. Check both connections independently using the product drawing.
What pressure can the assembly handle?
The pressure rating must come from the selected model documentation. Request the working-pressure limit and permitted service conditions. Distinguish working pressure from proof-test and burst-test values.
What inspection information is useful before ordering?
Records should identify the exact product model or batch. Request relevant dimensional, pressure, leakage and valve-operation results with their test conditions and acceptance criteria.
Installation and System Matching
Installation requires qualified personnel following the component instructions. Verify the mating fittings, seals, mounting and tightening requirements, then complete the applicable functional and leak checks.
The filling port must match the connected storage equipment, valves and pipework. Read our conversion kit component guide for related information.
