How long do flexible LPG hoses Last?
The British Standards recommend that flexible LPG hoses are replaced every 5 years. This is in part due to the aggressive nature of LPG, it slowly takes the plasticiser out of the hose material. Additionally other enviromental factors can cause the material to perish. It is important to use flexible hose that is designed for use with LPG. In the UK this is made to and will be marked with BS 3212:1991 (Type 2 (Orange) for HIgh pressure OR Type 1 (Black)for Low pressure) and the date of manufacture (mm/yy). In practise unless there is a record of when the hose was fitted it is best to replace any hose that has a manufacturing date more than five years old.
Many new yachts built in Europe have hoses made to other standards and are often have a tag marked 'Replace before' and a date. Again if this date is passed it is best practice to change the hose.
Flexible hoses that are attached to gimbaled appliances can be prone to chafe. It is worth checking these regularly.
