Flexible LPG Hose with High- and Low-Pressure Options
LUZHEN supplies 8mm LPG gas hoses for connecting LPG cylinders, regulators and compatible gas appliances. Hose construction, pressure rating, length, marking and end connections can be configured according to the intended installation and destination-market requirements.
Available configurations include:
5. Customized colour, printing and packaging
Important:
High-pressure and low-pressure LPG hoses are not interchangeable. The correct configuration must be selected according to the hose position, system pressure and applicable product standard.
LPG Pipe vs. LPG Hose
Although the terms LPG pipe and LPG hose are sometimes used interchangeably in online searches, they normally describe different products.
An LPG pipe generally refers to rigid or semi-rigid fixed pipework made from an approved metal or another material permitted by the applicable installation code. It is normally used as part of a permanent gas distribution system.
An LPG hose is a flexible connection used between compatible parts of an LPG system, such as:
1. LPG cylinder and regulator
2. Regulator and appliance
3. Cylinder and appliance where the approved system permits
4. Fixed pipework and movable gas equipment
This product is a flexible hose for LPG gas, not a rigid copper, steel or polyethylene pipe.
High-Pressure and Low-Pressure LPG Hose
1. 8mm Low Pressure LPG Hose
An 8mm low pressure LPG hose is generally installed downstream of a pressure regulator, where the LPG vapour has already been reduced to the appliance supply pressure.
Typical applications include:
- Domestic gas cookers
- Outdoor cooking equipment
- Commercial kitchen appliances
- Other approved low-pressure LPG appliances
The hose pressure rating and connections must match the regulator outlet and appliance requirements.
2. High Pressure LPG Hose
A high pressure LPG hose is used only in systems designed for pressure upstream of the regulator or for another specifically approved higher-pressure application.
Typical uses can include:
- Cylinder-to-regulator connections
- Cylinder manifold connections
- Specified commercial LPG installations
A hose should not be described as a high pressure LPG hose based only on wall thickness or reinforcement appearance. Its pressure rating must be supported by the applicable specification and test results.
Hose Construction
Depending on the confirmed specification, an LPG gas hose can include:
1. LPG-Compatible Inner Tube
The inner tube is selected for compatibility with commercial propane, butane and their mixtures under the specified operating conditions.
2. Textile Reinforcement
A reinforcement layer helps the hose withstand internal pressure while retaining the flexibility required for installation.
3. Protective Outer Cover
The outer cover provides protection against normal abrasion and environmental exposure. Required weathering, ozone and temperature resistance must be confirmed according to the product specification.
4. Optional End Fittings
The hose can be supplied in cut lengths or as a complete assembly with specified fittings, nuts, hose tails or clamps.
Hose and fitting compatibility must be confirmed before assembly.

Quality and Inspection
Depending on the applicable standard and purchase requirements, quality control can include:
- Dimensional and visual inspection
- Internal and external diameter verification
- Wall-thickness inspection
- Marking and batch-code verification
- Proof-pressure testing
- Burst-pressure testing
- Layer-adhesion testing
- Ageing and ozone-resistance testing
- Leakage testing for complete hose assemblies
- Fitting and crimping inspection
Inspection frequency and acceptance criteria should be agreed before production. Certification claims must apply to the specific hose model supplied.
For European vapour-phase propane and butane applications, relevant references may include EN 16436-1 for hoses and tubing and EN 16436-2 for completed hose assemblies. Other national standards may apply in different markets.
Product Features

- Flexible construction for convenient routing and installation
- 8mm nominal-bore option for common cylinder and appliance connections
- Separate high-pressure and low-pressure configurations
- Custom length, colour and product marking
- Optional fittings for complete hose assemblies
- Inspection documentation available according to order requirements
Selection and Safety
Before ordering, confirm:
1. Whether the hose is installed before or after the regulator
2. Required working pressure and temperature range
3. Nominal internal diameter
4. Hose length
5. Required end fittings
6. Applicable product standard
7. Destination country
8. Required certification and marking
Use only a hose approved for the intended LPG application. Keep it away from flames, hot surfaces and sharp edges. Do not twist, crush or excessively bend the hose.
The hose and fittings should be inspected regularly. Replace the product immediately if cracking, hardening, swelling, abrasion, fitting damage or leakage is found. Any replacement interval should follow the hose marking, manufacturer's instructions and local regulations rather than a universal fixed number of years.
Installation and leak testing should be completed by competent personnel.
