Used car values increase 13.5% in three months

used carUsed car trade values are continuing an “unparalleled shift upwards”, according to Cap HPI.

CAP hpi’s daily Live trade values reported an overall increase of 4.8% at the three-year point during the month of June, equivalent to over £625 per car. This rise follows the 2% increase during April and 6.7% increase in May, signifying that on average, values have increased by a staggering £1,700 or 13.5% in the last three months. This rises to £2,500 for one-year old cars over the same period.

Younger cars, up to one-year old, have seen rises of £2,500 in the same period.

“Consumer demand has remained very strong in June, despite half-term, great weather, and Euro 2020 to distract people.

“With stock-turn high, this has led to retailers requiring a constant supply of cars to replenish their forecourts,” said Derren Martin, head of valuations at Cap HPI.

“Well-documented new car supply issues resulting from several component shortages, have led to fewer fleet returns and part exchanges. This has caused demand to outweigh supply for the third month running,” he added.

BMW starts testing hydrogen-fuelled X5s

BMW has begun testing prototypes of the ‘i Hydrogen NEXT’. This will effectively be a hydrogen-fuelled X5. The X5s will be tested in Europe under “real-life conditions” as BMW gears up to eventually put a FCEV on sale, perhaps as early as 2025.

The i Hydrogen NEXT uses fuel cells developed together with Toyota and can carry six kilos of hydrogen in twin CFRP tanks. The fuel cell and “performance buffer battery” produce a combined 369bhp.

Frank Weber, member of the Board of Management of BMW AG responsible for Development, says: “Hydrogen fuel cell technology can be an attractive option for sustainable drive trains – especially in larger vehicle classes. That is why road testing of near-standard vehicles with a hydrogen fuel cell drive train is an important milestone in our research and development efforts.”

Can you bend silicone hoses?

Silicone hoses are far superior to the rubber alternatives, but what if you need a hose to bend into non standard shapes?

You may ask yourself whether you can bend silicone hoses yourself. There are many videos online telling you to heat the silicone with a heat gun. This is not something we would ever recommend. As well as being dangerous, you have the potential to ruin the pipe. If you go to fast or don’t heat the pipe evenly you get kinks which will damage the hose.

So what’s the answer?

We have specially developed two options to solve this problem which mean no more DIY silicone hose bending. 

bending a silicone hose

If you are looking for a really tight bend radius then take a look at UltraFlex. We discussed the benefits of these pipes In our recent blog. These pipes offer fantastic flexibility with incredibly tight bend radius using a wire spiral inside a specially convoluted section to create an extremely flexible hose connection. Find out more.

Or for smaller pipes we also have our Superflex Silicone Hoses. These are manufactured with a steel wire spiral embedded inside the reinforcement plies, allowing for flexibility not possible with most standard straight hoses. It will also take higher pressures compared to standard silicone hoses. Find out more

How to measure silicone hose diameter

Our silicone hoses are sold by internal diameter (ID) not external diameter. We measure this internal diameter with measuring calipers from internal edge to internal edge.

measuring silicone hoses

In order to select the correct hose, measure the outer diameter (OD) of the pipe you want to connect it to. This will be the same as the Internal Diameter of the silicone hose. For example if the outer diameter of the pipe is 76mm then you need to choose a silicone hose with a 76mm internal diameter (ID).

How often should hoses be replaced?

engine bay with hosesMost automakers and belt manufacturers recommend having your hoses replaced once every 4 years. Of course, this will vary with mileage – a car that’s heavily driven may need to have the hoses replaced much sooner.

How can you tell if your hoses need replacing?

There are several key things to look for to see if your hoses are coming to the end of their lifespan.

Look for:

  • Kinks
  • Stiff or brittle texture
  • Surface cracks
  • Bulges or bubbles

Inspect the hoses and note any kinks or obvious signs of wear. Squeeze the radiator hoses (when cool ONLY) and see how they feel. If hoses are soft and pliable, there is no need to replace them. However, if hoses feel stiff, crackly, or brittle, they will need to be replaced.

While squeezing the hoses, inspect the surface for small cracks. These can easily become big problems, as they’re the primary point for a “blown” hose.

You can also check where the hoses connect to the inlet or outlet pipe. Look for bulges or bubbles around the hose clamps, as this is a sign of impending failure.

Hoses can last a long time, but replacing them before they fail is always the better option. Once you have identified that the hoses need replacing then consider whether you want to opt for a straight rubber replacement which will likely need changing again in 4 years or click here to see what difference do silicone hoses make.

Do Silicone hoses stretch?

can hoses stretch

It has previously been suggested that if you buy a hose, which is the wrong size, you could put the hose in boiling water to stretch it. This will not work. You cannot stretch our silicone hoses. Our polyester reinforced silicone will NOT stretch between temperatures of -40C and 180C so water from a kettle will have no effect. If fact the whole point of silicone as a raw material is that it does not shrink, expand or crack at these temperatures.

Hoses are sold by internal diameter not external diameter. You need to choose the hose with the internal diameter matching the outdoor diameter of the pipe you are wishing to connect to.

It is imperative that you ensure you do not buy a hose which is too small. Even a few millimetres could result in shearing of the inner liner which can mean pieces of silicone make their way into your system.

It is also worth noting that buying a how which is too big will result over clamping which will damage the hose and create bulging for water or air to escape.

Troubleshooting issues with your silicone hoses

Upgraded silicone hoses

Silicone hoses are supple, chemical-resistant, anti-conductors, and can withstand a wide range of temperature extremes and therefore really do a great job at replacing rubber hoses. Whilst they are durable and long-lasting, there are a few things which can fail and these are mostly down to user error or lack of maintenance so we thought we would run through some issues you could come across.

Clogged hoses

You do not want your silicone hoses to clog, solidify, or get damaged in their operation. It is therefore imperative that you select the correct diameter the wrong one can render your operation ineffective. Temperatures, velocity, and pressure all change throughout production, so it’s important to factor these variables and be certain that you are you using the right diameter of silicone hose for your application.


Although vibration is a normal part of production too much vibration can compromise the lifespan. Heavy vibration can shake loose silicone hoses from their clamps or cause them to become tangled and warped over time. If you think you are getting too much vibration then ensure that you’re inspecting it regularly for worn or loose bearings, rotating components and misalignments.

Hoses Degrading

Not all hoses are created equal. While silicone hoses have longevity they still succumb to wear and tear over their lifespan. It’s important that you choose a silicone hose that’s compatible with your industry’s requirements. There are industries that require a fluorocarbon-lined silicone hose to handle specific liquids such as oil and fuel or the food and beverage industry that needs food-grade silicone. If your hose is degrading consider whether it has been selected properly for the job it needs to do.

The 2030 diesel and petrol car ban – what does it mean for you?

diesel carThe sales of new petrol and diesel cars and vans will end in 2030 the Prime Minister Boris Johnson has said. It’s part of what he’s calling a “green industrial revolution” and he’s pledged to invest more than £2.8bn in electric vehicles. But what do these changes mean for motorists?

Does it mean I’ll have to scrap my petrol or diesel car by 2030? 

Put simply no. The ban is only on the sale of new petrol and diesel cars. The average life of a car before it’s scrapped in 13.9 years, so we’re going see petrol and diesel cars bought just before the 2030 deadline will be on the road until well into the mid-2040s. What it does mean is that numbers will dwindle as car makers won’t be investing in the technology over the next decade. Petrol and diesel fuel will still be available at filling stations, but again expect pumps to gradually be replaced with chargers.

What about my classic car, will I still be able to drive it?

Unfortunately the jury is still out on this one. Some classic car experts predict that the bottom may fall out of the mainstream classic market, with classics becoming gallery pieces. While others predict a boom as petrol heads who can no longer get their fix with a new car switch to classics. But what is likely is an increase in taxes on classic cars and potentially bans from urban areas.
