FAQ's

Quality is paramount to us.
The latest & best Silicones are used to make Viper Performance Silicone hoses, we follow closely new developments in the industry and test new compounds.
We use purpose made High quality Polyester fabric or Nomex (aramid) reinforcements which will give the hose flexibility and high burst resistance. Our fabric reinforcements are embedded into the Silicone and applied by hand. All viper hoses are individually hand built, this allows our hose builders to check the hose and eliminate any air traps during build and make the perfect hose. Viper Performance make the toughest silicone hoses on the market. Many other brands and imported hoses use Low cost, low quality general purpose silicones hoses are usually made with very cheap silicone grades containing large quantities of fillers. (Fillers dilute and cheapen the silicone content and are very common in low cost budget hoses to bring the cost of materials down, they are a cheap alternative but do NOT give the hose any good mechanical tensile strengths or any life expectancy) Hoses packed out with with fillers will be far less reliable in the long run which is common practice with hoses made in the Far East or Asia to cut cost, this product is littered all over auction sites. Half of the material is half a hose, half the performance, Half the life expectancy! A good quality Silicone Hose will be much better than a rubber hose, a cheap quality silicone hose is unlikely to offer any improvement over an EPDM natural rubber hose, other than having a coloured hose! Don’t be fooled by claims of sellers on some online & Auction sites selling Blue hoses as Silicone here are a couple of videos: not scientific tests, but you get the idea…

Most of our silicone hoses have been pressure tested when designed. This is done to withstand maximum pressures allowed by the material. Our hoses are built to SAE J20 R1 Class A. specification Race teams including F1 teams to Rail, and Marine trust Viper! We also offer burst pressure testing service if required.

If pressure is high you will need roll beaded ends on the pipes your hoses connect to. The correct type of clip and hose size is also important.

Most hose manufacturers use the same method, but do check with others. Viper Performance measures the elbows lengths from the centerline of the bend radius to the cut face. There are some exceptions though so please check the video here to see exactly how we measure the legs on all of our elbows.

Yes we can! We have made several limited edition silicone hoses in the past. We can offer silicone hose manufacturing to match specific RAL codes. There is a lot of work and costs involved with this, we must also purchase pigments, mix and create a workable material. This is uneconomical for small orders. You need to budget from a minimum £650 onwards for making one off colours, plus the cost of making the hoses. To mix to RAL codes will likely cost in excess of £850
