What Is an LPG Hose?
An LPG hose is a flexible connection designed to carry commercial propane, commercial butane or their mixtures between compatible parts of an LPG system.
Typical applications include connections from:
An LPG cylinder to a pressure regulator
An LPG cylinder to a compatible appliance
A regulator to a gas appliance
A regulator to fixed installation pipework
The hose must be specifically designed for LPG service. General-purpose rubber tubing, water hoses and air hoses must not be substituted for an approved LPG hose.
This product category does not automatically cover hoses used for liquid LPG transfer, bulk loading, automotive fuel systems or welding. These applications require separately specified products and standards.
Typical Hose Construction
Depending on the product design, an LPG hose can consist of:
1. LPG-Resistant Inner Tube
The inner layer is selected for compatibility with propane, butane and their mixtures under the specified operating conditions.
2. Reinforcement Layer
Textile yarn or another suitable reinforcement helps the hose withstand internal pressure while maintaining flexibility.
3. Protective Outer Cover
The outer layer protects the reinforcement from normal abrasion and environmental exposure. Requirements for weathering, ozone resistance and temperature performance depend on the applicable product specification.
4. End Connections
A complete hose assembly may incorporate threaded fittings, swivel nuts, hose tails, clamps or other specified connections.
The hose, fittings and assembly method must be mutually compatible.
Key Specifications to Confirm
Before ordering, customers should provide the following information:
Parameter |
Information Required |
| Gas service | Propane, butane or LPG mixture |
| Application | Cylinder to regulator, regulator to appliance or another specified connection |
| Hose material | Rubber or thermoplastic |
| Internal diameter | Required nominal bore |
| Hose length | Cut length or finished assembly length |
| Working conditions | Required pressure and temperature range |
| End connections | Thread, fitting type and material |
| Applicable standard | Market or customer specification |
| Marking | Brand, size, standard, batch or date code |
| Packaging | Coil, individual bag, carton or customized packing |
Pressure rating, temperature range and service life must be taken from the specification of the exact hose model. They should not be assumed from appearance, colour or diameter.
Standards and Market Requirements
For European-market vapour-phase propane and butane applications, relevant references can include:
- EN 16436-1 — Requirements for rubber and plastics LPG hoses and tubing
- EN 16436-2 — Requirements for LPG hose assemblies
Other national standards may apply in Africa, the Middle East, South America and other destination markets.
The applicable standard and edition should be confirmed before quotation. Mentioning a standard on a website does not mean that every hose model is certified to that standard. Certification and test documentation must correspond to the specific product supplied.
Quality Control
Inspection requirements can be agreed according to the applicable standard and purchase specification.
Typical controls may include:
Raw-material and component verification
Internal and external diameter inspection
Wall-thickness and length measurement
Surface and marking inspection
Pressure or proof testing
Leakage testing for completed assemblies
Burst-pressure testing
Adhesion between hose layers
Flexibility and bending performance
Ageing, ozone or low-temperature testing where required
Fitting and crimping inspection
Batch identification and traceability
The required tests, inspection frequency and acceptance criteria should be confirmed before production.

Safe Selection and Use
For safe operation:
- Use only a hose specified for the intended LPG service.
- Confirm compatibility between the cylinder valve, regulator, hose and appliance.
- Keep the hose away from flames, hot surfaces and sharp edges.
- Avoid twisting, crushing, excessive bending or unauthorized extension.
- Inspect the hose and fittings regularly for cracking, hardening, abrasion, swelling, corrosion or leakage.
- Replace damaged or expired hoses according to the product instructions and applicable local requirements.
- Installation, leak testing and replacement should be performed by competent personnel.
If an LPG leak is suspected, close the gas supply when it is safe to do so, avoid flames and electrical switches, ventilate the area and contact a qualified LPG service provider.
