Cylinder Connection and Replacement Selection
The QFT1 is a brass natural gas cylinder valve with a listed working pressure of 20MPa and nominal diameter of 5mm. It is offered for compatible CNG cylinder installations and replacement applications.
Replacement selection depends on the cylinder interface and valve specification. Match the connection threads, sealing arrangement, pressure rating and installation dimensions. Vehicle make or model alone does not establish compatibility.

Which Connections Must Be Checked?
The cylinder and outlet connections require separate checks. Use the valve drawing and cylinder documentation to identify the correct thread forms, sealing surfaces and mating components.
Cylinder interface: Confirm the PZ27.8 connection specification and compatibility with the cylinder neck.
Outlet ports: Verify the arrangement and function of the ports marked 2-M12×1 female.
Sealing: Identify the specified sealing method and approved mating parts.
Installation space: Check valve dimensions, operating access and surrounding clearance.
System requirements: Confirm the required valve functions and any separate protection devices.
A matching thread designation does not establish complete system compatibility. The pressure rating, sealing details and permitted application must also match. Browse our autogas valves and spare parts when identifying related components.

Frequently Asked Questions
Is QFT1 a universal replacement cylinder valve?
No. Replacement requires a specification match. Provide the existing valve identification, cylinder connection details and installation drawings or photographs before selecting the replacement.
Can this valve be used for LPG?
This page describes a natural gas cylinder valve. LPG use requires separate documentation for the exact valve version. Do not infer LPG compatibility from the brass body or thread size.
What does the 20MPa value mean?
20MPa is the working-pressure value supplied for this product. Confirm it against the markings and technical documentation for the delivered valve. Do not treat it as a proof-test or burst-pressure value.
Does the valve include pressure-relief or automatic shutoff functions?
Those functions must be confirmed from the selected valve specification. This page does not establish that a relief device, thermal device or electrical shutoff is included.
What are the MOQ and warranty period?
The minimum order quantity is 10 pieces, with a 1-year warranty period. Confirm warranty coverage, exclusions and the claim procedure in the quotation.
Installation and Inspection
Installation requires a qualified technician following the cylinder and valve instructions. Confirm thread compatibility, sealing components and the specified tightening procedure before assembly.
The completed installation requires the applicable functional and leak checks. Follow the system procedure and documented acceptance criteria. Do not modify the valve body or substitute unapproved sealing components.
Routine inspection should cover the valve, connections and operating condition. Check for damage, corrosion and leakage according to the equipment maintenance requirements. Read our gas conversion system maintenance guide for related information.
